After taking it easy during the breaking period, I finally returned to my usual driving style!

Result: 282.2Km for 52.46L:eek: That's a great 18.59L/100:eek:

My chipped TT averaged 13L/100 with the same driving style!

Yesterday the gas price rose to 89.4 (regular) here in Quebec City; I haven't seen the price for the premium but it must be something around 0.96$!

I'm wondering what amount of fuel my car will use during the winter at -20C?

Well.... anyway I love my 8:D and it's a real party to drive:p

Wow... ummm that's pretty bad, I have 220Km on my tank right now and I'm at EXACTLY half a tank.

I am a LITTLE worried about the winter though, with more idleing and stuff.

TT, just curious, what is your driving style? I drive pretty hard too and if the Renesis returns THAT kind of fuel economy with high rpm driving.. :( Let's hope that gets better with time.

Well, usually I shift around 7k then select a gear that maintains the rpm between 4k and 5k... so if in need of acceleration, I'm not to far from the "power zone".

Once in a while, I go all the way to the readline :D but not that often. When merging on the highway, I can go up to 160km - 170km ( 4th gear) then ease back to 119 (6th gear)... you know... the tickets;)

When leaving the office, I get on a highway from a traffic light; if I'm on the first row, I'll accelerate up to 180 (being alone on the road) for about 2km (no policeman on that part of the road) then just before the overpass, ease back to 115 (6th) because there is very often a policeman on the other side ;)

I guess some people might say I'm driving to fast... shifting to high but... hey, I've what is suppose to be a high-rev engine with his power at the top of the band.

Since my last fill-up, just for fun, I drove like my grand-mother.... shifting 1-3-5, shifting at 3000k, trying to maintain the rev between 2 and 2.5k... so far, 85km and not yet 1/4 tank... guess I'll get close to 95km for the first 1/4 tank... but driving like that, might as well buy myself and Echo:p

By trying to get all the power (is it 250, 247, 238... maybe less :confused: ) this car need to be driven at high rev...

I think that 18L/100 is a lot for "not that must" power.

I love the car and the driving experience, but still...

p.s. Sorry for my "english writing"... being french canadian... well you know..

Hehe.. no problem.. Hmm.. you DO drive pretty hard but like you said it, this is a Rotary engine and it SHOULD be revved high for maximum enjoyment. :D Let's hope as the engine breaks in that goes down a little.. but 18L/100km is VERY high, ouch.

Well, I probably have a similar driving style, but slightly less agressive.

So far, my worst tank got my about 17.5L/100km.

Best case... at half a tank I'll have 150km on the car...

PS. I've got 3200km on her...

In 1400km of admittedly quite aggressive driving I have had 18/100 so far.

Well leaving it to rev 4-5K all the time you'll get horrible mileage.

You should be cruising at 2.5-3k on the highway. You won't get much better mileage with that type of driving that's for sure!

I'm getting 13L/100Km with granny driving.

Hehe.. I didn't even bother doing the math for the tank when I was at the 2-day Solo 2 Eastern Regionals in PEI the first weekend of August. I swear the gas needle was a real-time dial moving in time with the Tach...

Well, it shouldn't be HORRIBLE mileage using half of the Rev range.
My Civic SiR that I traded for the RX-8 got taken to it's 8000rpm redline every time I drove it, and I can't recall ever shifting it much below 5000rpm.. and it was still giving me mid-20s MPG.
It dynoed 140hp at the wheels too... pretty good for an engine rated at 160hp at the flywheel. Good thing it didn't have one of these Mazda 30% loss drivetrains... :(

Is that "normal" for a rotary engine? Can you get "adequate" acceleration shifting at 2-3K rpm? Adequate is a relative term of course.. but I have a feeling that 4-5K shifts would be appropriate for my style of driving and imo you shouldn't be getting "horrible" fuel economy while only using half of the available rpm range.. :(

My mileage has started to improve a bit. The last two were 13.4 and 12.5 L/100 km.

The main change I've made is that once I get stuck behind someone, instead of sitting in 4th at 4-5000 rpm, I just go to 6th.
Since you're stuck driving at their speed, you may as well save the gas.
Of course, as soon as a passing lane appears, I'm down in 3rd, but it still helps, from the looks of it.

BTW, we had a cold snap out here this weekend (you could see your breath kind of cold) and I noticed this morning that I had 245 km on the trip odometer and half a tank of gas left. Looks like the colder air might help with mileage. If so I'm looking forward to October.

I guess it depends on what you think is horrible. I'm getting about 13L / 100Km shifting at 3500rpm.

there is plenty of acceleration at this rate. Today I did this with 1-3-6 shifts and was ahead of traffic.

Well to me anything above 15L/100km is horrible. I'm just not used to getting this bad fuel economy.. I can beat on my Prelude like there is no tomorrow and still get 13L/100km. That's with 170 wheel hp. By the looks of it I'd get 18L/100km fuel economy with the same driving style which is unnaceptable.

You shouldn't be forced not to be driving in 4th gear at 4-5K in order to get somewhat reasonable fuel economy imo. 4-5K rpm is still only half of the rev range.. :(

You shouldn't be forced not to be driving in 4th gear at 4-5K in order to get somewhat reasonable fuel economy imo. 4-5K rpm is still only half of the rev range

exactly!!

I can't go under 17,5L for 100 km (with or without A/C) and my worst numbers are 19,8 for 100 km!!!

I'm starting to be very upset about this

3K rpm on the highway? That's downright dangerous - waaay too slow!

On my road trip to California, I averaged 11.8L/100km for the 6400 km. When cruising, it was at 75+ MPH (ie 4K+ rpm), when not cruising it was a lot of full throttle high rpm work on 2 lane roads (passing) or in the hilly twisties shifting at 6 or 7K rpm. NOT granny driving, by any means. The absolute worst I got was 15.6L/100km on a tank that combined hilly 2 lanes with rush hour freeway stop/go driving.

3500 rpm = 110Km/h Or close to it.

Those are ok numbers then.. Probably as good as it will get for this engine as it is right now. 15L is still very bad.. ugh.. I wonder if some cars are better on fuel than others for whatever reason? Maybe the current ECU map has something to do with the rather low fuel economy and hp loss. :confused:

For those that know, what kind of fuel economy do the TT RX-7's get?

Just filled up!

390Km 45.56L and I filled it to the brim (as I did last time).

That's 11.7L/100km!

That's not bad. That was mostly city driving. Although for me city is all 80Km/h roads but lots of damn stop lights.

There was also a few times when I hit redline, and 1 trip of about 40km that I kept hammering it.

I think it is getting better.

Very nice! :)

I have been putting some fairly good runs on my 8 by now, mostly at higher speeds, so I sat down and put all my numbers into a spreadsheet last night.

Here are my results (kilometers and liters) after 5 fills:

Wing, very interesting numbers! After my desastrous 18.6L/100, I filled up and decided just for the fun of it to drive like a granny...

Tonight I'm gone a fill up at Ultramar (thursday special - premium is 5 cents more than regular) and see the results but so far, allmost made 200km with half a tank.

For the last 200km I never revved the motor more than 4k, usually shifting 1-3-5-6 before 3-3k... never exceeded 110km on hway and cruising in the city at about 2.5k.

Most of the mileage was done as follow:
6 days at the office (5km city, 6 traffic lights, one hill to climb - 10km hway) = 12 x 15km = 180km

The other 20km was city driving... A/C was on most of the time

I'll get the exact numbers tonight but so far that about 13L/100km... and it's no fun to drive like that;)

I don't know if some 8 has a consumption problem while others don't (Gord?)

Anyway, I'll post my numbers tonight after my fill-up!

TT2RX8 at 1/2 tank I had less than 200Km at 3/4 tank I had 350Km, so it seems the bottom part goes slower!

Oups... don't tell me I need to drive like that for another week :eek: I can't stand it anymore... and who knows, these are maybe my last few weeks with the 8 (buyback..?!?) might as well enjoy it :D

Well, I'll fill up tonight and get my exact fuel consumption.

See ya tonight!

Well... I must admit, I'm very dissapointed!

Just filled up the car and even with my "granny" driving style I used 13.45L/100km (17.5 mpg us - 21 mpg cnd/uk).

If I look at Canzoomer, during breaking period he was able to achieve 11.3L/100 (city driving).

So far here are my results:

273.2km - 37.22l@84.9 = 15.69L/100km (Crosscountry, hway)
311.2km - 49.78l@84.4 = 16.00L/100km (Mix - breaking)
454.3km - 48.88@84.4 = 10.76L/100km (Hway - cruise @ 119k/h)
389.1km - 49.04@79.9 = 12.60L/100km (80%Hway no cruise)
280.3km - 40.20@83.4 = 14.34L/100km (Crosscountry cruising)
394.6km - 49.70@89.4 = 12.60L/100km (80%Hway)
282.2km - 52.46@88.4 = 18.59L/100km (Mix - having fun - redline)
213.8km - 28.75@89.4 = 13.45L/100km (Office + city).. see previous post


Total kilometers to date:2562.2km
Total liters filled: 356.03
Average consumption: 13.89 liters/100km
Cost per kilometer: $0.1186 per km
Worst tankful km/100l: 18.59 (Redline... stay between 4.5-6.5k)
Best tankful: 10.76 (Hway on cruise at 119kph)
High speed highway: ... not long enough
Average miles per US Gallon: 16.99
Best MPG: 21.93 (us) - 26.21 (uk-cnd)
Worst MPG: 12.70 (us) - 15.17 (uk-cnd)
(Thank's Canzoomer for the layout ;) )

If you compare with Canzoomer's stats, we average about the same (13.49, 13.89). I guess during the winter the mileage will get worst and for me, without driving hard all the time, there is no right economy to drive like my grandma;)

Gord... to bad you live so far away, because I would have like to meet you and cruise a "full tank" side by side and see how you can go "so far" with a tank!

One thing i would like to figure out is just how big the gas tank REALLY is.

Twice now i have run it down until the light came on, and one of those times i drove about 39km on the light.
In both cases I managed to pump about 52 liters in.
Considering my manual says it is a 60 liter tank, that is a BIG reserve.

OTOH, the last 1/4 tankful on the guauge seems to drop off REAL FAST.

I managed to put 54 L in after i ran about 40-50 km past the light on. I hope it's a 60L tank 'cause i plan on taking it deeper in the empty zone next time.

That makes sense, right 100Km on the light. Makes sense :)

i'd say it makes sense... :-)

11 posts up .... 12 now I suppose is my 11.7L/100Km explaination.

I now have another 40Km on the tank and it moved 1 dash. I'm headed to east of Montreal tomorrow for a wedding that should take the entire tank to get there. So I'll post those results Sunday.

Why? :confused: That's close enough imo plus whatever gas you have left down there is more concentrated with dirt particles.

I don't want to make an habit of it but i like to know where the limits are if i ever need to strtch it a bit.

Based on 54L and 40-60km after the light I would extrapolate that to 100km max.

i'm figuring 100 MAX so 80 could be achievable on HW driving.

Just filled of 'cause it was 78.9 at the Shell close to my place and the Petrocan was 85.9.

Put in 38.8 L for 339Kms

11.45 l per 100k

20.6 mpg US

24.64 mpg Imperial

about 70% HW and the 1st 150 K were at quite high RPM.

I can live with kind of comsumption.

I have a GS 6M

Ok here's my latest stats.

I filled up Thursday and then drove 50Km city driving. Then I went to Cornwall and filled up (2 people in car).

17.676L for 171.2Km = 10.26 L / 100Km!!!

Ok then I went to Montreal with 4 adults in the car, this was exclusively highway, BUT I got stuck in a traffic jam off champlain bridge for 30 minutes (WTF was with that, not sure because when it cleared there was NOTHING that should have stopped us).

I made it to philipsburg (hour out of montreal) then drove around with the wedding party, then another short jaunt (city) then back to cornwall and on to Ottawa.

My empty light came on BEFORE Vars! I live in Kanata :eek: I'm going to run out!

Made it home and made it to the station this morning.

Filled up with 57.59L! phew that was a close one.

Total Km driven = 527 on the nose. That's 10.9L / 100Km!

I'm thinking that isn't so great, but then there was 4 adults in the car and I did get stuck in that traffic jam! And I idled for awhile in the wedding parade.

So not bad!

That's 21.5 Miles per gallon. I don't think it gets much better than that.

Oh I hit redline once with all 4 people, the car definetely doesn't feel as fast with 4 people in it. And it didn't really kick.

Oh and this was 89 octane, I've been running with it, with NO problems. And the sputering on start-up is GONE!

Those numbers are starting to look "normal".. :) I wonder if the fuel economy will improve as the engines get more km's on them. It looks like it so far.

Oh forgot to mention I made 67Km on the empty, the needle goes WAY past the E :) Don't try to go more than that, this was ALL highway and it was CLOSE!

I think those numbers you posted plus my numbers show you can do quite a bit with car if you don't rive it hard. Drive it at 7k all the time and it's VERY VERY thirsty. If i can average 12 per 100k i'll be happy and live with it. Of course it's 30% less than with my 1.8 T Passat and it's 150 hp but i love my 8 so...

That's the only "drawback" to this engine right now imo.. If you drive it like it's meant to be driven, zoom zoom :D you get hit with terrible fuel economy. :( Could someone with rotary knowledge quickly explain to the noob here why exactly the rotary is so thirsty at higher revs?

fimichel, I had 4 people in the car, so yes, seems very good. 2 people or 1 would be much better.

It is a good idea to run it right dry once in a while, especially if you live where it freezes!

Gas is lighter than water.
If you leave some in the bottom all the time, you will accumulate some condensed water over a while.
Then when you DO run into that part, and it is freezing, bad things will happen.

Of course you can use the odd tank of gas/alcohol mix ( "gasahol", usually 10% mix) and it will absorb the water harmlessly.

Easily.
I went on a fairly lenghty highway run to Fort MacMurray and back this weekend. About 860km
On the way back I drove until the light came on, then immedediately filled up.
It took 44 liters.
As I am averaging aroud 14.5l/100km at fast highway speeds, that works out to about 110km of highway driving.

See my previous posts, I wouldn't count on making it 100Km, I was cruising on the highway at 103Km/h and only made it 67Km with 2.5 liters left. That's cutting damn close!

Now at 2700km, so this is my update:

Man you guys have cops in Edmonton or what? Average 160-210Km/h?? YIKES!

Seems like your gas is more expensive than, here that's odd.

I am burning premium AKA "Super", which jumped pretty badly in the last week.
I was paying in the $0.82 liter range a week or two ago, but this weekend I saw as high as 89.9 and as low as 82.5

Bear in mind that in Fort MacMurray, the prices are usually a bit higher than Edmonton, so that explains part of it.

As for the speeds, the highway to Fort Mac is decent, and was very empty this weekend. Except at each end you never see a police car. There is a stretch of around 200km with no side roads, towns, or anything..

In the case of the previous weekend we were on highways like 40 in southern Aberta in the mountains, and it too was empty and unpatrolled as the parks and roads were closed due to forest fire bans.

I also did a bunch of mileage on highway 2, which is typically 140+ all the time. The police do not touch you for anything under 145 at most times.

Just a follow up....

Still get awfull results:(

296.8 km, 52.011L = 17.52L/100, 13.47mpg Us or 16.09mpg imp.

Mix driving. city/hway (50/50)... no A/C! Driven the same way I used to drive my Audi TT (averaged 12L/100)

Oh well...

Are you people using 91 or 94 octane, and does it make a difference ??

And where do you gas up? I go to Ultramar and i cant get under 15 L/100 km . Maybe different gas company would make a difference.


MAdjoker

Madjoker, my last 3 tanks have been McEwen 89 octane, at 11.5L/100Km!

Of course we'll see how this tank goes as I have been redlining every which second! LOL

I have had my car a week and have 1600 km on the odometer. My results after 5 fill-ups are as follows:

1) 355km, 45.6L, 12.8L/100km, 18.2 mpg (U.S.), 21.9 mpg (IMP)
2) 193km, 25.6L, 13.3L/100km, 17.6 mpg (U.S.), 21.2 mpg (IMP)
3) 316km, 40.6L. 12.8L/100km, 18.2 mpg (U.S.), 21.9 mpg (IMP)
4) 365km, 50.3L, 13.8L/100km, 17.0 mpg (U.S.), 20.5 mpg (IMP)
5) 358km, 48.6L, 13.6L/100km, 17.3 mpg (U.S.), 20.8 mpg (IMP)

All of the figures represent combined mileage, and I would estimate the breakdown (in terms of kms) to be about 50/50 town versus highway.

I almost NEVER make any shift below 5000 RPM (lets face it, the engine is very relaxed at that RPM), but conversely I rarely take it much above 6000 RPM in daily driving. The last couple of mileage results have probably suffered due to the fact that as the car passed the 1000 km mark I made a few 0-60 runs, and a few more full throttle accelerations.

I honestly believe that one can get decent (around the 12L/100km range combined) if one keeps the shifts below that 6250 RPM and one doesn't go too deep into the throttle every time one accelerates.

My last fill-up (last night) was a real winner though: the gas station was out of "regular" gas, so they were selling premium at the "regular" price, 76.9 cents/L.. WOOHOO! :D

Well, I seem to be doing a little better than most, (or driving much slower!) I have just passed 4000k, and am now getting 23 mpg, plus or minus a little, (22.6/23.2, mostly highway) for the last eight fillups, all premium.

My light seems to come on exactly at the '50 litres fill' point.
I fill just till the pump clicks off every time then drive till the light shows, and find a gas station. It makes it real easy to calculate if the refill is always about 50 litres!

You may be the only one who has even come close to breaking the 10 L/100km (4000km with 8*50L). Just would like to remind everybody that the TC published numbers are 9.2 hwy and 12.8 city. The next best number was from Wing with 11.5 for highway.:eek: :confused: :(

This has become my biggest concern for this car. It's not the money, it's the principle. Most are getting above the 12.8 L estimated for city when driving on the highway.

WOW 23MPG? That's US gallon right? If so that's good!

My best number is 10.6L/100Km all highway, which is still aways from the 9.2 you should get.

Since noone seems to have compared this with the 7, here goes...

My 1st gen (12A, normaly aspirated, carb) did about 24-28 mpg (imperial).
Turbo II (13B) does 18-20, except for short runs (runs rich when cold) when it's noticably worse.
FDs seem to do about 18 on a good day, unless they've been played with, when they can be as bad as 12mpg (but considerably more than the 280 bhp!)

With my turbo II, driving style doesn't seem to make much difference, and neither does speed. I think the rotary is more efficient at higher RPM, although I've not seen any proof of this.

Maybe the ECU is running a richer map as part of a run-in procedure? or maybe Mazda have decided to set the map rich at the high end for reliability - but these numbers don't look as good as I'd expect...

Sean

Yesterday I phoned my dealer to schedule a "fuel consumption test"; someone phoned me today to tell me that Mazda Canada refuse to do any kind of testing during the "break in period"... which is 10 000 km

Since I only have 3000 km I won't reach that number before the "buyback limit"!!! They told me that my consumption should "greatly" improve after that.

I said "Great, can you put it in writing specifying that if I doesn't improve, they will buy back the car... " Oups... sorry they can't do that, finally they gave me the phone number of MCS (Mazda Customer service)... same answer..

So is the famous "run rich, reduce power after 6250rpm" number = 10 000 km

WOW that's INTERESTING.

Same answer? VERY VERY Interesting!

Unfortunately I won't be at 10K till next year!

Well guys, i'm at 6050 km as of today and i will probably reach the 10000 mark just before the snow arrives. unfortunately i won't be driving this baby in the snow so it could take until april before i know for sure.

Oh... forgot to mention on my previous post that the lady at MCS explained to me how to reproduce the test they use to determine fuel consumption and that way see if my car is ok or close to it!

City driving: drive your car at a constant speed of 33km/h
Hway driving: drive your car at a constant speed of 77km/h

Yeah... that's my kind of driving.;)

Yup, drive at 33, you'll get stopped for blocking traffic!

That's not how they do the test, they AVERAGE 33km/h with like a 10 Km trip with 5 stop signs or something like that.

The highway is about right though 77Km/h.

The issue is though, that they test EVERY car like this, yet I can blow away EPA on other cars, but not the RX8

Ok here's my latest, I didn't drain the tank because gas was only 65.6 today! So I filled up, incase it goes up!

Anyway 320.9Km with 41.158L (accurate enough for ya? ;) )

12.8L / 100Km (18.38US MPG / 22 MPIG)

This was ALL city driving, and at least twice a day I redlined the car in first and second. Yesterday I even bounced of the rev limiter a few times. That was cool, because the car doesn't just loose power like some it just bounces off of it.

Wow... if my fuel consumption was like yours, I would for sure keep my 8! but at 18L/100 mixed driving... I don't think I'll keep my car.

Might come back to the 8... next spring maybe, when some drivers have reach the 10000km mark and confirm that the consumption is a lot better.

You're lucky to get that kind of milleage, but since Mazda doesn't want to test my car, I have no other choice I guess... :(

I know we've said that many times but Wing and myself are getting very similar mileage on our respective red, GS, 6M car !!

Guess we are easy on the throttle or we got the best cars... :-)

my last tamk was 14,6 but i drove it kinda hard just to see how bad it would get...

Hell, for 2 days I drove like a maniac ;)

Guess I'm lucky.

Oh I'm using 89 octane.

About time! :D

Seriously, next tank of gas, I'm turning off the DSC.
Sometime next week I should see if that helps any.

Hmm, 10k. I can't see me making it to that this year.
Although I am planning a trip up to Ontario the end of the month...

Yup, ummm I floored it doing down this one straight and the car was sideways for like 30 seconds, I started off a little crooked :eek:

Finally broke the 15 L barrier did 13.56 L/100 km this week, first time I turn off both dsc and the car thingy light light up every time I pull out of the garage, coincidence ?? we will find out with next tank full.. Also first time the gas tank aint fill up with Ultramar super ( well 50 % ultramar and 50 % petrocanada 94 octane )


This tank trying petrocanada 94 octane only...

On my side... no improvement:mad:

Last tank = 18.88L/100km!!!! No a/c, no dsc/tc!!!!

I have close to 2000 Km on mine (6speeds , red GT) . So far I kept all my gaz receipt but haven t really ad them up to see what kind of consumption I ended up with from the very beginning.

I did 250 Km of highway back and forth last friday, most of it in 6th gear, for wich I immediatly figured my consumption. I didn t take it easy at all, I even reached 230 km per hour at one point on my initial 250 km. I averaged 12.2L on that initial 250 km A/c was on.

On the way back a/c was off, the two windows were rolled down and the moon roof was opened; I averaged 11.7 L/ km.

It' s not great but it is quite surprising when I read the few horror stories here.

Sunshine, do you have a GS or GT?

TT2 i wonder.... do you rev it up at 7k everytime you shift?? Or maybe you are in the city ALL the time? Québec city doesn't have that many traffic jams... :-)

Hi f1...

I usually shift between 5 and 7k (below that, there is no accelaration :( ); My driving is at least 50/50 hway/city... sometimes even more hway.

Here is a typical day to day ride: Home to hway = 2.5km, Hway to exit office = 13km, Exit to office = 2 km). Last week I drove this ride 10 times (2 x 5 days)= 175km, about 60km Hway (driving to different dealers to test drive other cars... :( don't know yet if I'll keep my 8)... and less than 40km city driving... result: my wonderful 18.88L/100!

The same kind of driving with my TT always average between 11.7 and 12.2km/100; I was close to redline most of the time with my TT shifting 1-2-3; to get the power out of the Rx-8 you need to rev it a bit; and we must remember that 6000rpm is only 2000 "rotor" rpm... which doesn't seems that must to me ?!?

I sure would love to drive side by side for 100-150km with Wing and see the kind of consumption I would get compare to his.

This week-end I filled up with regular fuel... so far, 112km and the needle is between the half and 3/4 mark... seems to be about the same...

Even if I don't drive that must (20 000km/year) that's close to 100$/month more than the TT... 200$ of hard earn money before taxes :eek: ... that's the reason why I'm still unsure if I'll keep the car :confused:

You drive it normal to hard which is fine and fun. I drive way more conservatively since my point record with the police isn't that good. :-) If i ever go to Québec city anytime soon i'll let you know and well follow each other for 100K or so just to se...

F1... I might go to Montreal next week... I'll let you know!

You guys do know that the GS model is a 4port intake system and that the intake on the GT is a 6 port system, right?
In a nutshell, the GT will drink more gas when the all ports are open.
So when you guys are posting, please state which type of Rx-8 you drive as consumption should differ between the two.

GS and GT got the same Engine.

Its 4AT and 6MT that got a different Engine/Powertrain setup

I just got 11.1 l/100km on an automatic run to Toronto and back
from Southampton--450 kms and 50 l.'s. Used cruise control down most of Hwy 6/10 at 115 kms/hr. Have not changed oil yet.
AC only on 35% of trip.
Gord

As stated Wing ; I drive a red 6 speed GT.

Here's my CITY driving from my fill-up BEFORE heading to T.O.

27.85L 213.3 KM = exactly 13L/100Km.

This was all city.

I'll have to check my car for the receipts from the trip to T.O.

Wing,

What is your current milage, type of gas, etc?

I'm at 3200Km now, but that last tank was like 2600Km or so.

This was 89 octance McEwen gas, doesn't seem to matter really I filled up with Esso 87 coming back from T.O. and it seems the same 1/4 tank left with 420km or so.

This is from the trip to Toronto. I filled up right before leaving.

Then drove into Toronto, then out to the meet. Got stuck in traffic for a while. But this was about 95% highway at 100Km/h approx. Although I did get it up to 170 at one point and a few 130's.

46.726L for 436.1Km

10.7L/100Km

I'll be filling up again tomorrow, that one will be interesting. Because it was the same highway trip on the way back, so same roads and all. But on the way back I travelled 120Km/h with MANY jaunts up to 150 and 1 up to 210!

Wing, on your way to TO were you cruising right at 100Kph? Seems awefully slow and boring... did it on purpose?

I am envious. Drove Edmonton to Red Deer and back today ( 350km round trip) All highway, set cruise to 125kmh in 6th ( rpm was below 4000).
Got 15.5l/100k

I don't get it Canzoomer... your car has a flaw or something because when i drive on HW at 115 i get close to 11 l per 100K.

I have a GS 6M that has , of course, no aid in traction whatsoever and i love it that way.

f1michel, I took highway 7 which is an 80Km/h 2 lane highway, I didn't cruise, I used my foot :) and had to pass on numerous occasions. Highway 7 was a pretty fun drive actually.

Although I got a big stone chip :( and just dust from another truck made a bunch of tiny little pin head spots on the hood.

The paint must be REALLY soft, because in 3 years with my tib I didn't get this many nicks! I ordered the touchup paint hopefully I can fix them.

That's too bad for your paint. I had the same problem about 2 weeks after i got the car, that stupid car in front of me was pulling a trailer on the HW (120kph) and hit a bump.... saw a few dozen little things fly up and couldn't slow down enough.... i have about 3 or 4 small chips. I'll wait a bit before touching them up, i'm afraid the touch up will be more visible then the actual chip.

Did an old man boring drive to Quebec City (from Laval) yesterday PM.

95% of the drive was done in 6 th speed at 110km/hr using the cruise control.

281.2 Km; I`ve used exactly 30.242 L for an average of 10.75L/100km.

When I saw that, I decided that the boring drive wasn`t worth it since I averaged 11.7 on that same trip done a week before (driving alot more aggressively). I therefore came back averaging +/- 140 km /hr. Haven`t filled up yet so, I don`t know my exact consumption for the trip back.

In Quebec I stopped to fill up at Esso on Neree-Tremblay street around 9:15pm (thursday night Sept. 18). There was a red RX-8 parked there. Didn`t seem to have no one sitting in it. I filled my car up and by the time I turned around to go and ask the clerk who`s car it was; it was gone .

Would it be anyone of you guys by any chance? Maybe you TT2RX8?

Now that's annoying !!! I don't even treat my kids this way.

Another tank 10.8L / 100Km

This was on the trip back from Toronto averaging 120km/h with some FAST sprints and redline driving like mad.

Doesn't seem to matter what I do.

I'm down another quarter tank with 120km which seems about on par again for 11L/100Km this is all city so far and driving like crazy!

I'm going to make a spreadsheet.

Are you filling it with 87 or 91?

The last tank was 87, but normally I use 89, haven't noticed a difference.

i'm using 87 for the last 6-7 tanks and it hasn't made a difference. I still can make about 11.6 L per 100K when i drive it like my mother would. If i just push it a bit it goes to 12.5

I found the ticket to better mileage.
At least on the highway.
Keep the rpm below 4000

I made about 330km of highway, and 45 of city driving.
On the highway I ran in 6th at 4000rpm, which is 126kmh

I got 13.4l/100km or 17.58mpg.

Not by by any means "good" but lots better than the 15.-16.7/100km I was getting before on highway runs.

I looked in the RX-8 book tonight, and see that the first change over of the intake tracts happens at 3,750rpm, so I bet if I kept below that I could do quite a bit better.
Of course that is only 115kmh (71mph).
Legal but very boring.

Also, from a range point of view I got 372km on this tank with a 49.75l fill. At that rate I could have gone about 450km (279 miles) on a tank.

Lesson learned:
Drive close to speed limits, and keep revs below 4000 and mileage is acceptable.
I bet if I kept below 3750rpm i could break into 20mpg.

not that I would particularly like to drive this car that way.
If I wanted to do this I would buy an Echo.

I also get 13-14 MPG with 75% "gentle"/25% "aggressive" driving, and it didn't make any difference whether it was 87, 89 or 91 octane.

The procedure Environment Canada uses is:

Simulated Highway Course
The highway fuel consumption ratings are based on a simulated 16-km simulated highway course of 12 minutes with no stops. The top speed reached during the test is 96.5 km/h, and the average speed for the duration of the test is 77 km/h. Ratings are adjusted to reflect average, real-world driving conditions on typical Canadian highways at posted speed limits.


As you suggest, that would all be below 4000RPM, and probably all in sixth gear. I cruise at 120, which is probably just at 3750RPM. 115 would probably get better milage.

Well, I tried driving with the DSC off for an entire tank. I still only got 13.48 L/100km so that didn't help.

If staying below 3750 rpm is going to give us that much better mileage, can I please have a different 6th gear? One that puts me at 130 km/h at, say, 3700 rpm instead of 4100 rpm?

My first tank of gas, I got approx. 15.2L/100km. Not that great, but it was like 90% city driving, and since I'm new to stick I figure I probably wasted a bunch of gas overrevving it in 1st gear to get it going.

Ok Zoom Zoom this one is for you :)

I drove like an idiot this past week. ALL city driving. I filled up today.

14.1L/100Km

Here's what I have logged so far, I'm missing the first month :( But I started to keep a spreadsheet. Average over the month is still 20.1MPG or 11.8L/100Km

Just wanted to find out if most people are getting over 400KM's on a tank now? I know some of you aren't and some where in the past by reading this thread.

I thought I just ask to find out how the 8's are doing now.

Thanks

White_GTS :D

drove like my father who's 85 for my last tank and got 21 MPG over 400km, the light still wasn't on at that time so i know i would have gotten close to 500km. But that was at 100kph, cruising and 90% highway. Not fun...
