Hi guys, can you please state the type of Rx8 you are driving (4AT, 6AT, 5MT or 6MT) and give a rough estimate for your FC... And also some tips on Rotary Engine Oil. Mineral or Synthetic... and also how often do you change it...

Cheers...
Newbie Rx8 Driver.

Dave C.I.M, diam diam.. If you want to Pang Sai, go ahead.. remember to flush.

Svper, mines 06 make, 4AT. Used to be using Shell 20W50, now on Idemitsu racing Mineral Oil. Change every 4000-4500km. FC is 7.5km/l. No mods, running on 18 wheels.

Hey dave, you know this is a Asia thread. They do their own thing, talk their own talk. Leave 'em be.

BTW i bought another vehicle for a daily driver so that I could get better gas mileage. The vehicle?

2002 Chevy Silverado. Seriously.

Carbonrx8,

Thats precisely what i am doing too... I have a honda Civic as well..

Thx INXS... but thats amazing... Got a friend on 4AT too... uses shell V-power. Does like only 5km/l... even if it's his mum who is driving it... stock 4AT... no mods...

Cheers...

Wow 5km/l is abit too extreme right. I am getting average abt 8km/l +-. Me '04 6MT. The worse i heard is 6.5km/l.

The mum cant be heavy foot and rev when she drive right? hahaha
maybe the family all racer...... kidding.

Holy shitz dude. 5km/l?? On a stock car??

Thats ridiculous and a SURE sign that something is very wrong with the car bro. Go get it checked out - seriously.

What size wheels you running? Is your tire pressure at the recommended levels? Are you using fuel additives like Octane boosters? If you are? Stop. They aint good for the car bruv and certainly aint good for your wallet. When was your car last serviced?

I'm on a end '05 6MT and I do 375km on a full tank. This is purely urban driving with next to no expressway driving which would probably increase my FC. That works out to be about 7.2km/l on an average of a 52L full tank (I think the tank is 55L but I dont like leaving it that close) for me. Unfortunately the only expressway I could use to work is the CTE and we all know how much of an 'express'way that really is.

Last thing I'm using Caltex. Find it does actually clean your engine somewhat and I feel that the engine is smoother and more responsive than when I was using any other premium fuel (and no I dont work for Caltex just in case ur wondering lol).

Fuel additives has nothing to do with fuel consumption.

And using the rx8 on the expressway may actually give u better mileage than urban driving.... for other cars not sure. FOr rx8, very sure.

6MT '04... full tank 580km :Freak_ani


i also find that traffic jams (CTE-3 beeps) eat my fuel......n clutch...

My point exactly. Thats why I said for him to stop using them.

Yup you are right on that which is why I stressed that I'm doing mainly Urban driving. Stop start traffic = burn more fuel than cruising at consistant highway speeds.

And since ur online now Ivan, you joining us 2nite or what bro?

Y do u need to press me for this answer, even knowing i online or not? Anyway thanks for inviting me to answer ur question.

The way the forum is now, if i dun come, everything will start all over again.... and indirectly.

anyway will be there to pay for outstanding drinks.

Pardon me, my english is "O" level standard only.. hope it doesnt come across as rude.

rainne xiao mei mei, how u do 580km?!?! dunch bruff us, u go jaybee increase ur fuel tank size siboh?

Keen to settle this once and for all.

Its a lot easier to sit down and talk than to do it via forums. Forums have this nasty habit of conveying messages that you dont want.

Case in point when you had to apologise for your english (which seems fine to me) just in case it offended me.

I am of course not offended in the least - but it reinforces my point that forums really aint the best way to communicate or solve issues.

Once again I dont need you there to pay for drinks. I hardly even know you, why should you pay for me? I would however appreciate a smile and a handshake.

The rest would then be up to just how sincere the two of you really are in settling things and I guess thats the whole point of this meet. Just find it a shame that things have turned out the way they have thats all.

Anyway I'm done trying to push for a resolution. Not like I'm getting paid to do this shit anyway. Would have been nice if everyone got along well and we had regular 50 car Sepang trips. But if it does not happen then tough shit - thats life right?

buying drinks is for generally all rx8 members, be it new or old. My usual practise anyway... I dun collect money then buy for u all. this type of thing i no geh gao one...

Wah!! Then stingy farker like me will benefit by getting 2 free drinks tonight. :p: Kidding......

By the way, I think you guys are hijacking the thread. :p: :cwm27:


6AT on 235/19 wheels, no other mod. 370 @ 52L for first tank. Will update on if there is a diff in subsequent tanks.

6MT '04... full tank 580km :Freak_ani

580km per tank? How on earth did u manage that? My best is only 520km per
tank...mostly night driving on the expressway, without mods except for rims,
redline it twice, rest of the time drives like an auntie, had to pump 54l of
petrol back in after that...so it works out to be ard 9.5km/l... :ylsuper:

As for the engine oil, only use mineral n synthetic oil made for rotary...ordinary
synthetic will damage ur engine...mineral oil confirm must change every 5000km...
synthetic rotary oil can stretch up to 10000km i heard but best still change during
5000km...

Rei.. dun think synthetic rotary oil can stretch til 10,000km. Most probably the majority of the engine oil would have been burned off by 5,000km anyway. I think you should still change at 5,000km regardless of mineral or synthetic engine oil.

don't tell u

Hahaha...another myth busted...anyway, thats wat my authorised workshop told
me...they told me to change the oil after 10000km if i'm using synthetic...at least
now I know how much they really noe abt the rotary...thanks for the info,
bro... :biggthump

Hmm...but that only means 1 thing...monster garage....here I come...its a state
emergency...I need new oil...
heehee... :mdrmed:

normal driving, i change gears at 3k+ rpm and ya, also bluffing a little

not sure if u find SPC petrol seems to last longer, cos i was trying to empty the tank but seems can't finish (my car dislikes spc). but vpower seems to evaporate

My 4AT RX8 manufactured in 05 but i just got it brand new last Nov.
I got 7.2km/L. I'm on a 225R17 45R. No mod but with grounding and Voltage stabilizer...
I'm using 20W50 mineral and hope to switch to 10w30 Royal purple sythetic. Using Shell 98..

Aiyah, the 580km per tank method must be down to the taxi/rocker combo. ie when going down hill, kick it into free gear plus the driver has to rock himself back & forth in his seat to add forward momentum. If got passenger, must also get them to rock back & forth in their seats to add to forward momentum. Old Irish trick.

My max has been 525km per tank before wiping the seat off my forehead and roll into a petrol station. All stock except for the F1 super-strakes mod.

6MT '04... full tank 580km :Freak_ani

dude... u really gotta let us know ur secret to this mileage...

those who wants to know, pls pay me S$1

THANKS :smileysho

I heard that first run -n (which i am going to do diligently, correct me if i am wrong) 1k change (have to be mineral), 5k change (also mineral) than after that you can choose to drag 10k on synthetic or every 5k on mineral... Is this theoretically true? what difference will it make if i go from synthetic to mineral and vice versa?

Cheers...
Newbie Rx8 Driver.

Sorry. I just over reacted. I just could not stand the thought of another fuel thread. Sorry. My bad. Oh, I hit 21mpg with my last tank. At work, don't know the conversion. I never got that much before and it was combined city/highway.

hearsay that day someone already booked the oil at monster.....hmmmmm....i wonder who...haha

Hearsay book 2 can somemore...rumour has it, its a blue 8...with greddy oil pan...
I wonder who... :rolleyes:

We are all talking about 61Litres fuel tank capacity right?

We are all talking about 61Litres fuel tank capacity right?

Mazda spec the gas tank as 61L, but you fill up before it's really empty. so 50+ Litres is common.

Mine is 6MT 05, Almost all stock. average 400Km only when red indicator lit.

yea.. i think most of us would get close to 400 or just a little over 400.
so, for those who are hitting the 500s constantly... well done..
stil very curious how to get a hint of that... anyone?

wah 500km mileage....well done..

i try to drive grandma style oni can hit 390-420km. worst family car overtake me sian...so dun care liao

Hi - Mine 2weeks old 6AT

Just passed 1500km

1st 1000k oil changed - Shell Mineral 20/50

Gas used: SPC 95 ( got 14% discount )

Air-cond level : 1st level with temp between 22-23C

Mod : MM 18" wheel, Goodyear Respec2 (225/45)

driving style : maintained @ 2500rpm for gear changed, crusing 6spd between 85-110km/h rpm @ 1800 -2000. ( 50% expressway & 50% short distance driving )

so far only using MT twice and RPM hit 7000k....bcos Buang tong kena chio by a Celica & a new civic... but shiok lah !

Average Mileage is 7.5km/litre or 50-53 litres for 400km.
( By the way my 03 CRV best is only 8km/L with 17" Wheel )

Now, i'm testing it see what different mileage achievable with filling up full-tank and filling up only half-tank driving. ( In the past experienced with my slivia & CRV got better Km with half tank about 20km more...strange ? )

cheers !

if any 8 fc around 400km. good liao lor...

my lancer fc is 400km for a 50l tank. means 8km/l. wah lau....

My question after all this reporting is: how much is the difference between AT and MT 8's in terms of fuel consumption? Also between 4AT vrs 6AT; 5MT vrs 6MT.

93 unleaded??????????? be prepared.....

The guy is from africa..different rating for gas I think

93 unleaded??????????? be prepared.....


93 unleaded is same as the guys using in USA. 93 is a PON rating. equivalent to 98 RON.

see this http://en.wikipedia.org/wiki/Octane_rating

Holy... Its Chemistry already... haha... BTW... what petrol is best for run in period... and after run in? I am planing to go V power during the first 1k and than the next 5k... after that 98 continuously... comments?

Cheers...
Newbie Rx8 Driver.

Africa indeed and right now, it's summer, In the highveld (high altitude region of South Africa) 95 RON is hard to come by, in the coastal areas it is everywhere.

Also, I haven't seen any difference in mileage between when using different grades, only the idle vibration of the gear lever decreases when using 95 RON.

Perhaps the reason I get 520km on a tank is because I drive until the fuel guage needle is below the last marking. That means, it is REALLY empty, most of the time.

I've tried using the 98 from SPC and it is adequate but somehow feels 'rough' after a while.

I think it comes down to personal choice, but for me I prefer Caltex Platinum.

U're a brave man my friend....

eh how come your fc better than mine :( I only got about 335 @ 52l. Now 2nd tank doesn't seems to be any better. Mine only 18" wheels ...
1st tank of fuel. refuel 50 liters @ RM95 for 380KM. maximum rev up to 8,500rpm (four times) and change gear at around 3,500 to 5,000 rpm (normal drive), very good respond for all gears. Mid range power not as powerful as the first 3 gears, however, good enough. 7.6km/L for mixed drive on this 1st tank. with more consistent drive should be around 8.5Km/L.
Engine oil level is still between full and low. ;)
-6MT Mazdaspeed limited version, wheel 235/18

I used to pump v power all the way til my mileage was ard 13000km...seriously
bro, I can tell u there is absolutely no difference between 98 n v power...or at
least, if there is, it is not significant enough for me to tell...although I must say
that the difference are clearer in a piston engine...

So, I think it wld be much better for u to save the money n go for 98
instead... :cool:

U're a brave man my friend....

You mean his balls are HUGE :D:

hi there i've just bought the 07 rx8 6speed AT, so for engine oil, wat is the suitable oil for rotary, either mineral or synthetic? and any idea on where can i get fog lights (original) cause mine is PI, so can't get from the mazda dealers, plus for fuel comsumption wise the 6AT consumes better than the 4 speed and the engine is not very hot...cause rotary very hot mah! the engine start up is also quieter leh! :rock:, should i put in a voltage stabiliser, auto start with car alarm, and a open port air intake for my RX8, or shld i just leave it as it is?? :rock: :ylsuper:

My fc after 2 tanks of 54L is 410km = 7.6km/l mixed drive - traffic and highway 40/60. I have the same question. what is the right engine oil to use? i heard normal mineral oil is fine and some said synthetic is fine... I am thinking I will just go for the semi synthetic oil, Shell Helix Plus 15w/50 is ok? anyone have any feedback on using this? :)

I would suggest going to Google to find the answer to this new question. Maybe they may have an answer to this unique topic.

My 6AT FC going down the drain..... Sad.......

1st tank - 370km/52L with Shell
2nd tank - 350km/53L with SPC
3rd tank - 330km/53L with SPC
4th tank - 220km at quarter tank mark!!!

wah so bad ah?

How do you drive.

I get approx 420km from full to light on quite consistently. approx 52L. 6MT JDM. approx 8km/l.

I get max 260km/50l - 90% short drives of not more than 5 click, always in heavy city traffic/congestion.

Drive on auto mode. Gear change at 2500rpm. Occassional 6000rpm when trying to overtake.

Wah, that's really bad fc... I suggest to send to service centre for a quick check-up. Although auto normally "drink" more but not like this. Hopefully you will find a "cure" to it. :)

I am running on 235/35/19. Could it be SPC petrol. Feels like the car is running on flat tyres. Did a check on tyre pressure, everything seems in place at 240psi.

Dun worry silver z
i getting 6km/l normal driving..seldom whack.

i'm 5km/l, always whack, and heavy traffic conditions

5km/L!!! wah i ot the worse was 6km/L.
U must really wack it hard. u must have reach 100km/h before any next traffic lights.

Last night I was done with my 4th tank at 320km/53L. Now on shell 98. Lets see how it goes.

Wow! And I am not refering to Windows Vista. Silver Z: 320km on 53l? What model do you have? AT or MT?

6at

I noticed I get better FC for caltex platium, u guys might wan to give tat a try. But of coz I am paying a higher price for it :hahano:

I using caltex gold with techron. hehehehe

I using caltex gold with techron. hehehehe
same same. used to use esso98. caltex seems smoother.

just finished the 3rd tank, filled up 53L for 410KM used, it is quite consistent that I get 7.7km/l and I am using shell super from the first tank.

Then.. tt concludes. SilverZ's 6AT is a replica.

Then.. tt concludes. SilverZ's 6AT is a replica.

Ok ok!!! I confess!! Its a Geely Double-8. :lol2:

basket I avg 350km full tank!

6 SPD M ... 3 years old

1st tank - 370km/52L with Shell 98
2nd tank - 350km/53L with SPC 98
3rd tank - 330km/53L with SPC 98
4th tank - 320km/53L with SPC 98
5th tank - 360km/53L with Shell 98

Finally completed my first tank. 7.5km/L. using Esso 8000. on 18", 235F 255R.

75% highway, 25% city

4th tank done with 410km with 53L refuel ;-) so far so good... stay at 7.7km/l

I clocked 8.32km/l, 40%highway and 60% city. Rev a few times.
Mine a 4AT. On average, it is around 7.5km/l. Maybe due to VS, grounding and a lighter rims.

I clocked about 8.2km/l on 50/50 highway/city for my 6-sp Manual JDM full stock. Do not drive hard only occasional revving.

I was clocking an average of 8km/L on my 5MT, fully stock. 60% city, 40% highway.

Used Caltex Gold(98) ever since I owned it.

Strange strange: switched from Vpower to Platinum techron , full tank mileage from 280 now increased to 350..... hmmmm

Thats odd? My fc is ard the same wif Vpower n 98... :confused:

6AT done 430km...55L

7.8km/l guess its alright FC

Still running in engine... hope it gets even better =)

4AT done 458km on 56L using SPC, 70% urban, 30% highway. Surprised as well, as using 19" wheels with 265 for the rears.

8.17km to the litre.

spoil ur torque converter then u know..

wha i did not know rx8 can save fuel... lolz i must go home and try it...

Mine's a 4AT and readings are very similar to yours. It's a ltd series sports edition bought in Aug 06.

Anybody noes what that means other than the extra trimmings. Is there a sports 'engine' for this model?. Shud hv tried some other bros 4AT last weekend meet to compare.

Sorry, I'm a sotong when it comes to technical stuff.

6AT Just done 500km...54.9L

Caltex 98

9.1km/l pretty pleased with the FC

my goodness, you sure it's an 8 you were driving? :Eyecrazy:

How did u do that?? My 6At is doing an average of 7.5 km/L/

I'm definitely driving an 8 bro =)

As to how i'm getting such FC,

Think it has something to do with me not using the AC during my morning drives to work

I'm normally up early so tt i dun hit any bad traffic, hv a pretty light right foot too (That helps)

Mostly in AT mode

who got the best mileage?

4AT on 16" stock rim
60% city driving
6.7km/L

anyone here who got the ECU re-map and seen any improvement in FC?

lol....after remap dunno why my foot heavier - worse FC.

anyone here who got the ECU re-map and seen any improvement in FC?Akan datang...

anyone here who got the ECU re-map and seen any improvement in FC?

gotta remapped ecu, no diff in FC, still abt 7.5km/l

just feel the fan kick in earlier and stays on for a shorter period when u turn off the engine.

incidentally, just recently switched from shell 98 to shell 95... SAME FC eh! no diff! hehe.

Just 2 week old 6AT with stock 16" rims doing about 7.2. Hopefully gets better after my oil change and run in in 2-3 weeks time..... but guess 2 things gonna happen after run-in that's gonna add to the FC

1) gonna be more and more tempted to be...."heavy footed".... haha
2) very tempted to get 18" rims that's probably gonna to poorer FC

Well.... keepya posted then

hi guys, would just like to find out some things.

1.) do you know the fuel consumption of the RX7 Gen3?
2.) can the RX8 renesis engine be used on the RX7?

hope to hear from ya!

1. I only managed bout 300kms per full tank in my previous Rx7 Fd3s with minor mods.....which quickly turned to bout 230kms with a few more serious mods.......

2. Why would u wanna put a Renesis engine in an Rx7 anywayz........ I don't see y it wouldn't fit BUT...... Most street comp Rx8's are running FD engines...... Even the DRIFT Rx8's are mostly running FD RE engines.........

i found that the fuel make a big different. we tested out the AF with a mass flow sensor, found that malaysia Air/petrol actually make the AF ratio Rich for the car.

im getting pretty good fc's since i changed my engine oil . i used to only get about 400km/53l but ever since i went for servcing and im using the re rotary oil im getting an average of 420/53L.

Mine is 4AT... 2 yr old...
Shell 98... usually pump 50 litres...
Driving style is usually 2.5k to 3k rpm at about 90-110kmph, mostly in auto-mode
70% urban (lots of start-stop), 30% highway
70% aircon on, 30% off (set to 24 degrees, fan speed 1 or 2)
Using Idemitsu synthetic engine oil
Warm-up of 2-3 mins before driving off.
Tires: 18" rims, Bodykit: Veilside 1 kit with Mazdaspeed spoiler

Mileage - 350-360km per full tank, or 3.6-3.8km/l

3.6 to 3.8 km/L??

Or rather you mean 7.2km/L.

6MT will have better consumption.

Good days i get 430-440km per full tank
Not so good days i get 370-380km per full tank.

Up to your driving habits larh.

Also depends on your mods and ecu recalibratioin.

Tatoo@

Just did a full tank on my recently bought 1 year old car, 4AT, stock condition, no mods. 475km on about 60 litres, Shell 98. Ave drive to work = 27 km 1 way on CTE-PIE.

I really wonder how u guys get such good FC... I'm doing ard 5.5km/litre on my stock 4AT. 90% city driving though and but i have quite heavy foot and likes to rev the car every now and then :)

probably the reving then.. I also rev... but no more than 4000 rpm because meet up with traffic next moment ha ha......

this car needs to redline every now and then......routine maintenance! and you can forget about good FC for driving rx8.

this car needs to redline every now and then......routine maintenance! and you can forget about good FC for driving rx8.

Roughly redline for how long? how many seconds/min? Any particular gear selection or can select neutral gear and just rev?

redlining this car is more fuel efficient then letting it idle. :P

so far for me (km/l):
8.7, 9.2, 8.5, 8.2, 7.8, 8.1...

Rev to 6-7k twice per trip (until I hit 3000km, when I will rev to limit). I'm using a combination of break-in methods from the FAQ.

CoupeM is right... revving high vs low, not very much difference in FC. I find the biggest non-driver factor is start-stop traffic.

Simple physics. Kinetic energy lost via braking is wasted energy, and has to be recouped via converting more chemical energy back to kinetic energy. 1st law of thermodynamics. The more you have to brake unnecessarily, the more fuel you will have to burn later.

Roughly redline for how long? how many seconds/min? Any particular gear selection or can select neutral gear and just rev?

I think better rev while in gear, otherwise the lack of airflow might not be good for the heat situation. No need to sustain redline, just hit it can liao...naturally, like in normal driving. Stay on a low gear longer in order to hit it, otherwise matah will come and say hello to borrow your licence..

I was in neutral the whole time while driving down a 23 mile mountain stretch... and guess what, I went from a quarter tank to OMG! THE LOW GAS LIGHT IS ON! How the hell did it consume so much gas when I was in neutral the whole time?!

how does a car move on neutral??

actually our fuel consumption veri good oredi.

if you drive the bugatti veyron, when u turn the 2nd key and hit 407km/hr,

the 100 litre fuel in the tank get sucked in 12 minutes!

how does a car move on neutral??

I was driving down a huge mountain in California, the mountain is called Mt. Baldy and it's all downhill so I stayed in Neutral the whole time.

Using 55L of Shell Formula 95 (95 UL), clock 480KM

After my 5th tank, Esso 5000, still around 6-6.5km/l. my god
:banghead:

cause leaving it in nuetral is as gd as letting the engine idle. this engine drinks more during idling. must make it work for its meal.

Renesis SE3P,

Never leave car in neutral going downhill for any stretch of time. You may get brake overheat and even failure and go off the road !

Oh, I see, I thought I was going crazy when my mpg went down quick when in neutral....

Yikes, I drive a lot and America is full of mountainous terrain especially when you're traveling from one State to another, every time I hit a downhill section, I always leave it in neutral. I'm going to start leaving it in gear now, I also need to change my brakes too.... thanks for the tip.

I generally do 75%-80% highway driving during off-peak hours, and so usually average 8 - 8.5km/l. Best was 8.991 = 9km/l.

At the 1/4 mark it's usually anything from 380km to 400km.

And oh, I'm light-footed as well!

what's your car model? 4AT? 6AT? Type S?

Anyone currently using fuel saving devices on their 8? How's the FC after that? Great if can share your experience.

Seriously considering one after my 6km/l FC. Not much difference whether I drive light footed or slightly heavy on my 6AT...

what's your car model? 4AT? 6AT? Type S?

4AT / 18" Toyo T1R / 33 PSI all round

Hi all bros, i am pretty new in this forum, getting my 8 in Sept. I understand that keeping smaller rims enables better FC but Just wondering if keeping a 16/17 inch rim will actually big diff in the FC .

My experience with my current 18" tells me there's little or no difference using them; lighter rims lower profile tyres COULD possibly mean less weight and mass, or otherwise just a negligible increase.

I mean, I've yet to hit anything less than 7.5km/l (but I do mostly highway driving!)

04 6MT USA 15-19 miles per gallon. normally about 280 miles on a full tank. tank is about 15 gallons.

I'm doing around 5.5km/l n heavy footed. Tried to rev less but also not much diff hence I gave up. Might as well just whack lah... haha!

Anyway, i'm 90% city driving so i think 5.5 is still acceptable to me...

Thanks for the reply! will be checking out some fuel savings device once i get my 8. Will update bros here if there's anything worth looking at.

there isnt any fuel saving device. if there is, power stations would use it to save fuel already. a 10% saving to them is in millions

just did my second tank, 445km with 54.3 litres Shell 98. 1 year old 4AT stock. But something strange. I did 250km up to the halfway mark shown on the fuel meter, so that means I only did 195km on the remaining half. Driving profile didnt change much other than slightly poorer FC on a SAT with city driving while doing errands. Perhaps that means what is shown on the fuel meter is not exactly proportional?

I suppose its like that...I always get more mileage on my 1st quater tank... :)

All along i thought Fuel tank is from big to small.
The top part is usually larger then the bottom and thus you can drive more distance.
I believe the fuel tank look something similar to a cone.


Anyway i am getting between 6-7km/l.
never rev much. but give up on asking abt petrol anymore.

Has anyone used the Octane Booster before? any particular brand? NOS? Snap?

About the disproportionate mileage/litre of petrol on the fuel gauge...
The needle drops much faster in the first quater than last quarter for me...
when u drive on a full tank with 60 litre of petrol which is equivalent of 60 kg, the fuel efficiency is poorer than when there is less petrol in the fuel tank after the second half. Hence the fuel efficiency is slightly better in the second half, thus the needle drops slower in second half than the first half...
my 2 cents worth...:Eyecrazy:

my 2 cents worth...:Eyecrazy:

Actually i noticed that mine is quite proportionate. 70km for 1st quarter mark, 80km for both 2nd and 3rd quarter mark, warning light usually appears ard 260km or 30km into the final quarter and i'll usually drive on for 30km or so before refuelling.

If what you said is true, maybe someone can try topping up to only half tank everytime or even just $20 of fuel daily and share with us if your fuel efficiency improve? :lol2:

Mine really plunge really fast on the last QTR. But its strange that fuel efficiency is higher when u are heavier? It should be the other way round? My first QTR I can do 120-150km, second QTR 100km. third 110km, last one 85km. hmmm?

Another observation, i was stationary on a slope (about 30 deg upwards) and tank was 1/8. within the 1 min I saw the needle go from 1/8 to zero. Cool.. But when got moving again on level ground it bounced back to 1/8. nevertheless still quite a big fluctuation.

Has anyone tried the ion accelerator called Calski before on their 8?

The calski is damn gd man....i put like 20pcs and my fc went from 7.2km/l to 7.25km/l

Mine was 350/53L when stock. Then with Trust exhaust, it was 290/53L. Then now with some cheapo $200 air duct(exhaust still Trust), I am now getting 370/53L.

What's an air duct?

Hi SushiFan,

It works like pieces of magnet attached to the car fuel line.. intention is to change the molecular structures of the fuel so that they can break down more efficiently - creating better power and incidentally (though not all cars experience it) reduce fuel consumption. Came across it in Wheels magazine, went check it out with some friends who drive celica and REX and they also recommend ... but i not sure if the calski can do anything to an 8..

thats about 8km/litre, guess most brothers here manage an average of about 7-7.5km/litre from what's being posted so far.. so u are above average :)

The calski thing is it a legal mod? I guess with such devices they must give significant improvement to the FC else its waste of $$. E.g. If device cost $200 and improves 7.2 to 7.25. It means every litre you travel 0.05km more which is 0.7% improvement. So it should save 0.7% of your fuel about 0.7% x $100 (ave) for a full tank of Shell 98 = 70 cents. $200 divide by 70 cents = about 286 times you need to refuel to break even investment = 286 x 450km (distance per full tank) = 128700km. wow...that's in 6 years (@ 20000km per year) if you ever keep your 8 that long?

Hi SushiFan,

i like the way that u work out your maths haa...

Anyway my friend pass me this website to look for more information http://www.warom.net/calski.html , u can go read.. what's written is increase torque/horses at no addtional fuel consumption ..

I going try it out after i get my 8, now carless so cant comment much..

Any other brothers who has tried this may want to comment?

cheers

Ok thanx! but do you know if this is a legal mod that can pass the 3rd year inspection?

its 100% legal..

dun waste ur time on these kind of fuel saving gadgets... they are useless, period. Most of the time, they are psychological. U r better off spending ur money on other stuffs.

Having said that, want to play car, dun worry abt petrol. Wan to worry abt petrol, rx8 not the car for u.

I have noticed that my fuel consumption has improved by 5 to 10% since I changed my spark plugs. recently. I noticed a fuel efficiency drop a few months ago but attributed it to needing a re-flash or something. I should have done this earlier than when I did at 41k.
Stop your worrying and just change the plugs earlier.

How can a magnetic field affect molecules that don't react to magnetism? Fuel molecules are hydrocarbon chains, carbon and hydrogen atoms only. An electric current must be passing through molecules of that sort before any magnetic effects can be produced or induced, like in graphite or carbon nanotubes.

My guess is, unless there are microscopic ferro-magnetic particles (eg iron) flowing with the fuel, the magnetic field that Calski produces doesn't affect the fuel flow at all.

Hi Bro Rumboo!

Hope u been having great fun with your 8 :)

Anyway this is wat i have extracted from the calski web site with regards to your question:

How It Works?
Calski ION Accelerator work instantly when installed. As the fuel passes the magneto hydrodynamic effect field; that penetrate through rubber, polyethylene, aluminium, copper and stainless steel hose. Oxidation takes place rapidly and releases free radicals called carbonium ions (CH3+).

Clustered fuel molecules which normally burning too slow or would not burn in the power stroke; are separated and permitting to mix homogeneously with the required 12.5 to 14.5 oxygen, stoichiometric ratio. This is how to increase the percentage of fuel burned in the power stroke, maximizing fuel combustion is accomplished, and without changing the chemistry of the fuel.


I may have mis-interpreted what's was being explained to me with regards to the molecule alteration- Pardon me for my lack of chemistry knowledge! Anyway i hope the above makes sense. I will give it a try for sure once i get my 8 due to recommendation from pple i know.

cheers!

Dont do this kind of useless mods la...might as well donate the money to me. Serious.

i'm driving a '04 4AT...and the machine is guzzling 52-55L for 380-395km...

so approx 7+/-km/L

We should have a competition to see who can acheive the best mileage. Each participant pay $10. Winner takes all.

how about a competition to see who got worst mileage?

I only can get about 300km.

i see you all getting like 400km-450km....thats like fwah.....

seriously....i really wonder how so many of them can get 450km sia....not joking...i am kinda jealous.

my car only about 360hp...wun make a lot of difference to fuel what. give and take 50km....i shd be expecting 350km before the orange light comes on.

Well, my 5th tank today. 438km @ 56L. Not too bad. But I guess my better FC is attribute to more expressways driving.

seriously....i really wonder how so many of them can get 450km sia....not joking...i am kinda jealous.So many of them? Keke.. I oso one of "them" leh.. wanna make u jealous so I gotta drive like a granny. Btw, hapibday..

Thanks craz! It's been great fun, especially driving through the old Lim Chu Kang twisties that I have to take now that I'm doing my ICT..

Regarding the Calski explanation, it sounds quite dodgy to me. Lots of scientific sounding terms thrown together, but not making much sense. Eg, "hydrodynamic effect field", I've googled this:

http://en.wikipedia.org/wiki/Magnetohydrodynamic_drive
and
http://en.wikipedia.org/wiki/Magnetohydrodynamics

It basically means that the fluid must become electrically conducting before it can be affected by the magnetic field, like I mentioned earlier. Seawater can, becos it is essentially an electrolyte (ionic solution) with all the Na+ and Cl- ions in it. Even then, an electric current must be passed through it. Petrol, however, does not contain free ions to allow the flow of electrons/electricity. Not sure how petrol can be affected by the field to even produce the free radicals as claimed.

The ideal stoichiometric ratio quoted is correct, but I'm sure the device can't detect exactly how much fuel/air is in the combustion chamber, as that is constantly varying according to demand. Especially not if it is upstream from the intake manifold, along the fuel line. How can it then affect the stoichiometric ratio on its own?

I'm still not convinced, but thanks for taking the trouble to post the Calski explanation, though!

Rotary newbie here. 2wks old 6AT on stock 16"rims.

1) Been reading this thread but found no favourable answer to which oil [mineral (rotary or normal) or synthetic (full or semi)] is the best for the renesis rotary.

2) Any difference (on FC) or damage done if using RON95. Currently using Caltex Gold or Ron 98.

2) Search but no results. How to break in?

Thank you in advance. Cheers :)

Hi go drive!

I'm also newbie here.
Just got my ride 3 days ago!
A white 6AT RX8.

I also have the same question as u.

So where will be going for your servicing?
where do u stay?

wooooo, best tank of fuel on my 6th tank. 479.1 km on 55.35L of Shell 98. 1 year old 4AT. But this anomaly prob due to over 90% expressway driving. Had 1 day where travelled non-stop on expressway, about 150km clocked doing consecutive milkrun type of profile.

Take a look at this thread, should answer most of your questions:

http://www.rx8club.com/showthread.php?t=63747

Btw, there's no favourable answer regarding which oil is BEST because there's a lack of hard evidence and a properly constructed experiment. There are, however, oils which you should NOT use because they're suspected to be behind some engine failures. Can't remember which ones, though. =P

1) synthetic oil such as idemitsu, royal purple, trust, RE, HKS. Specifically for rotary.

2) better use RON 98 as it gives you better mileage and protection.

3) Break in or Run in? don't rev more than 3000 RPM and till 1000km. After that you can enjoy the car.

i cant remember which workshop i'll be doing the servicing as the workshop is arranged by my PI.

Labour & Parts are free for 3 X (e.g 1k, 5k & 10k km).

Anyone bought from PI got a better deal on maintenance wise?

i'm staying in sengkang
my PI workshop is Gary 's Engineering at paya ubi industrial park.
Anyone went there before or serviced there before? I wanna find out whether that place is good a not, if not i think i'll bring her to other place for servicing.

My warranty is 1 yr and free servicing labour for 5 years.

How's your fuel consumption coming along?
I haven't finish the first tank yet. but mine is at the 1/4 mark and about 320km liao. Hopefully i can hit 400km before the light comes out.



hi bro..i'm is a pearl white too. residing in cck. urself?

i cant remember which workshop i'll be doing the servicing as the workshop is arranged by my PI.

Labour & Parts are free for 3 X (e.g 1k, 5k & 10k km).

Anyone bought from PI got a better deal on maintenance wise?

bro rumboo & muscleman, thank you for the tips.

320km at 1/4 tank? no chance to hit 400km before light is out.

320km at 1/4 tank? no chance to hit 400km before light is out.

I think no chance too. The last 1/4 finishes very quickly.
Much quicker than the other quarters.

yeah, the last QTR is very fast, I estimate it about 60-70km only.

I must be doing something wrong...

Got my 6MT second last week and only achieved 260km on 55litres of V-Power. That's like less than 5km/l which is way below the average. Granted, it's not totally emptied out yet but the fuel tank indicator light is up already this morning.

Will check out how my second tank does and update here again.

V power traditionally has poor FC. But driving style is also a factor. Still 260km is a little the ermmmmm low... or is this the characteristic of a new car?

Thanks sushifan for the info. I myself also felt very ermmm... :Eyecrazy:

Didn't know that V Power suffered from that.. :banghead:

Anyways, pumped Shell 98 today instead - will see how that goes.

Might wanna try Esso's 5000 next - liked the fact that they have DBS ATMs at most major kiosks.

Hi all,

Just sent my car for the 1k service.

Sent to MBMWheelpower at Sin Ming.
Was informed by them that they used Mobil Semi-syn 15W-50.

Any advice on this Semi Syn using on the renesis?

Thanks in advance.

Hi Go drive,

The renesis should not use syn or semi-syn at all. It can use mineral and certain brands of synthetic such as idemitsu, trust, RE...

You should just ask for mineral for the 1k, 5k & 10K. After the free servicing is done, go else where for servicing such as MG or GR. Then go for the above mentioned syn.

hmmmm synthetic oil not good for the engine in the long run. should get it changed at ur next servicing

hmmmm synthetic oil not good for the engine in the long run.............The renesis should not use syn or semi-syn at all

Where do you get this information? Is it fact or fantasy?

Have read about it on several websites when you do a google search on rx8 + synthetic oil. Fact or fantasy I guess up to the reader to decide?

bro, fantasy la.....

there are synthetic oil meant for the renesis..... if rotary experts are using them, i dun see wat kind of damages they will cause the engine..

260km? U must be driving the hell out of ur 8...I notice u said u got ur 8 last
week...did u run in ur engine? I'm driving a 6mt too...I pump v power too when I juz got it...I got 420km on my 1st tank n 520km on my 2nd tank...so I dun really
think v power has ver bad fc...

My PI workshop is MBM...they noe nuts abt rotary...put in the same engine oil as
ur car n insisted its alright...ended up I have to go straight down to mg n drain
out their oil n replace it wif mineral oil...

Any form of synthetic or semi synthetic oil except meant for rotary will eventually
hurt the engine in the long run...my advice to u is to drain it out n replace the oil
as soon as posible...

wow! 520km!!! I can only get 430km with my 6MT and am driving very softly :(

I am running in and max that I have got was only 420km. 6MT as well.

Not so much driving the hell out of it as opposed to not being used to it. countless times i can't even get the clutch biting point correctly. Think i wasted lots of fuel from that alone.

My 8's a second hand and has 5500km on it so i assume no longer need to run it in?

Now i'm really starting to worry that something's really wrong with my fc. I'm like doing only half of your 520km. Anyways, pumped 56l of 98 two days ago and now at the 3 quarter mark having done only 50+km. I suspect I'm going to achieve roughly the same fc again... :banghead:

I am running in and max that I have got was only 420km. 6MT as well.

hi winn, noticed you said that your max was only 420km. What petrol do you pump and what was the lowest mileage you got from full tank?

btw, out of curiosity, how often on average do you guys change/top up the engine oil? every 5000km or less?

hi winn, noticed you said that your max was only 420km. What petrol do you pump and what was the lowest mileage you got from full tank?

Hello,

I am only on my third tank even though I have got the car for 1 month. haha..

1st tank was 381km and pumped back 54L but i figured out that because it wasn't really a full tank to start with.

2nd tank was 418km and pumed back 52L.

now on the 3rd tank. mileage looked pretty low. i have used up more than hald a tank and mileage is only 200+ odd km..

Winn :banghead:

yeah you prob hit 350-380. second half of the tank is typically less than 200km.

btw, out of curiosity, how often on average do you guys change/top up the engine oil? every 5000km or less?

I do it 5000km as recommended by the garage that I send my car to..

wow! 520km!!! I can only get 430km with my 6MT and am driving very softly :(

Actually, thats not the best I've ever done lah...best I ever got was 583km wif ard
3 litres of petrol left in the tank... :)

But its very fustrating when u c sunnys, civics, lancers n even toyota liteace zoom
past u lah...
hahaha... :mdrmed:

I dun suppose that there is anything wrong wif ur car lah...a lot of members here
got different results when it comes to fc...

If u do want better fc, I did a search on the forum n found that if u drive ur car
below the 3500rpm mark (thats abt 111km/h in 6th gear), u would get better fc
because the secondary port of the engine is not open n thus saving fuel or
something like that lah...

Anyway, hope this will help u...enjoy ur ride... :)

R u doing a lot of city driving? On my previous ride, i get approx 10.5km/litre when i used to stay in jurong west hence 90% of the time i'm on expressway be it to work or to town. The moment i moved to town area, despite the same ride n driving style, my fc dropped to 8.5km/litre as i'm almost 95% city driving.

My 8 is giving me approx 6km/litre which i'd think it's reasonable as i should be doing perhaps 8km/litre which is about the norm that fellow drivers r getting.

Gee, i am only doing 320 - 350 km per tank. Think it has something to do with my 18' wheel and the PSI.

Current front on 34 PSi and Rear on 30 PSi.

Anyone got any advice?

I do it 5000km as recommended by the garage that I send my car to..

Haha.. ok. Realise that I was too kiasu liao :p:. Bought spare from MM and keeping it in the boot cos I went to Shell and noticed that they didn't sell minerals - only have syn or semi-syn.

Thanks Rei for the info. Really enjoy driving the 8 so far.

In general I try to drive change gears around the 3k mark but sometimes not enough discipline... :lol2:

Anyway, just got informed by a friend that I really need to change my bad driving habits :Eyecrazy: cos I usually engage half clutch all the way when going up those circular steep car parks.

Btw, noticed something strange just now - when I released the clutch, there's a loud sound coming from underneath the hood and i tried it a few times and the sound kept re-occuring. It sounded like "thack" whenever i release the clutch pedal. I tried it again later when the car was much cooler and the sound disappeared.

Yeah, doing mostly city driving cos I travel by nicoll highway to get to city area.. Based on my calculations, my first tank was doing like 5km/litre :scratchhe

Conserve momentum when driving. Plan a few steps ahead, look for holes to slot into in traffic, anticipate traffic light changes, gradient, etc. Excessive unnecessary braking wastes momentum and fuel. So does excessive unnecessary acceleration, like when you lose too much speed at an uphill section due to poor planning.

Don't forget to use 6th gear early, as I find that usually, after the initial quick acceleration, you have to ease off the pedal to match speeds with traffic ahead of you. Some guys remain in lower gear for too long just to maintain speed. This car has enough hp at 6th above 50km/h on flat ground to accelerate and keep up with most other vehicles. Eg, when filtering onto a road, I normally do 1st-2nd-3rd-6th, as after 3rd I'm already at 80km/h or so, revving to 5k at most. 1st-2nd-4th-6th is a pattern I use a lot too.

A lot of guys I drive behind always brake when getting to a gentle bend in the road, then accelerate away at the exit after slowing down too much. The worst thing is, I am also forced to brake. Seriously, at 70km/h, your chances of sliding off a gradually bending dry road in Singapore is very remote, even with a liteace. Steer gradually and smoothly, load up the suspension smoothly, and passenger comfort is not compromised.

A soft 'Thunk' sound is normal for the clutch, but for me I can only hear it when the engine is off (when it is quiet enough). It's louder if you release the clutch suddenly.

Practise increasing the speed of your gear change..it's a good way to compensate for accelerating more slowly due to less revving. Just make sure you shift accurately, or you'll wear out your syncromesh.

FC right now hovering at abt 8.2 km/l, cos of 75% city driving recently, itchy right foot, and being a noob at double-clutching.

Seems like guys are more heavy footed.:lol2:
I know a few guys who hardly hit 300litres in their rx8

As for me, its 450litres minimum, with my stock 4AT
sometimes I drives without aircon, not too sure whether its true, but I've heard people saying that it does help on minimising the petrol consumption

mLynn.... you mean 450km, right? ;-) As for myself, the fc is around 420km for 54L petrol...

sometimes I drives without aircon, not too sure whether its true, but I've heard people saying that it does help on minimising the petrol consumption

I watched an episode of Mythbusters where they proved that driving around with the aircon off and the windows down is better for FC than with the aircon on and the windows up.

...or was it the other way around?:evil_laug

yup i do that every morning when i go to work. i think it def helps.

I've tracked the last 30,000 miles on my car and I average 17.6 mpg. This is a mix of city / highway with PLENTY of agressive street driving.

Just to share my personal experience

got my 8 about 3 months ago. now about 5k+ into my mileage.

previously, my fuel consumption was like 6km/l thereabout. Terrible. :banghead: the worse was 5.840km/l on Shell 98, which means less than 300km on a full tank. Mostly city driving with aircon.

had a sudden change in fuel consumption recently. the past few tanks mostly highway driving on Shell 95 and I even got my highest fc at 9.766 km/l on my last tank . not sure if the mileage had anything to do with this..

that's some hope for those who just bought their 8 and started with bad fc:)

Hi guys,

Recently purchased the ScangaugeII with the purpose of monitoring FC, my findings as follows:

In the 1st 10-15 mins of ur trip, the FC is BAD, can go as high as 35L/100km (ranging from 25-35L/100km). Pls note that I have remote start and my car is sufficiently warmed out when I reach my car. :SHOCKED:
This may explain y our FC is so bad when u do a lot of city driving.

After which the reading will gradually drop to abt 14-17L/100km, which is my norm. Also to note that I have tons of ICE behind and I dun drive like Miss Daisy. :naughty:

Lastly, if u go on night cruises, I can get 9-11L/100km with windows/sunroof open as well as my ICE blasting away.

Another thing I found out is that when u start to rev after the FC has stablised, it will remain abt that level. Eg. abt half an hour back when reading is abt 11L/100km, i started to "play" with a Forester for a couple of mins, redlining all the way, FC only dropped to 12-12.5L/100km. But when u play when the reading is abt 25L/100km, the petrol station is waiting :rollingla

FYI: I drive a MM 6MT. Frankly, I think the Scangauge is the best investment I've made for my car thus far :ylsuper: Before u think I have any commercial interest in this, I do not. Frankly, the person whom I bought the gadget from needs a little more work in his approach, more like a "ai lai mai sua" attitude plus his technical knowledge is even worse den mine :uhh:

The readings make sense. I suspect that my fc got better due to the longer distance travelled. And by the way, one strange thing is that the aircon does not seem to affect my fc much, which doesn't make sense..

Scangauge sounds like a good investment. May get one soon:)

how much did u pay for this device?

300 plus... doesnt make financial sense if u ask me but i am pretty anal abt my FC, those who know me will know tat :hahano:

Frankly, the person whom I bought the gadget from needs a little more work in his approach, more like a "ai lai mai sua" attitude plus his technical knowledge is even worse den mine :uhh:I'm guessing you didn't get it from me. Better to be specific so others don't get the wrong idea.

I'm guessing you didn't get it from me. Better to be specific so others don't get the wrong idea.

Eh, u selling too? Aiya, should have gotten it from u instead...

Yups, I got mine from another fellow, sqflyer is amazing when it comes to technical stuff..

Well, don't have to get from me just because of technical stuff. I still share what I know if I got the answers.

update on my FC improvement, JDM 6MT.

1) stock w/ 15W40 SL mineral: 405km per 55litre
2) RP Supercat: 425km per 55litre
3) remove the plastic infront of stock air duct: 445km per 55litre
4) 10W30 SM mineral: 470km per 55litre (got these oil cheaply, will svc more often)
5) waiting to remap, will see how much the FC improve again.

These thing that I've done not only improve the FC but power and response as well.


>>still looking for MS wing......

Ur mileage tells me u never whack ur car...later carbon built up...

this is amazing......my 8 is 10th mth old now and I've never even come close to 380 on full tank b4......

I only average abt 300-320 at most....:Eyecrazy:

But will have to confess tat I maximised my Renesis very often la......isn't tats e way to go???

Pros, pls advise........

cheers

What's going on here? I just changed my sparks and air filter and I am getting over 520km per full tank. Sure you dun have a leak? I dont notice a huge diff between redlining it everyday or not. Smooth driving mate! Failing this.. try the Fred Flintstone driving method. Worked for him in the past.:lol2:

Try to drive without using very much brakes and it might help improve your driving style, safety! and also fuel consumption.

i drive smoothly normally. but redline it atleast once a week. Is this enough?
