I just came back from a week-end trip and I barely broke the 9 l/100km barrier for the first time with my 8. I got a nice 8.99 l/100km (or 26.2 mpg) for the whole trip. That means 667.4 km (or 417 miles) per tank. I know it's definitely NOT a record but it's a nice change from the 15-16 l/100km I usually get with combined city-highway driving. And to think that about 50% of the journey was through the mountains!

J'te crois pas. :Eyecrazy:

Sti, j'ai de la misere a passer le 350km colisse.

Damn, that's impressive! I've never achieved that in my 8 :(

I thought my 21mpg was good... :suspect:

*looks at his pathetic 12mpg achievement.. up from 11* *sigh*

*looks at his pathetic 12mpg achievement.. up from 11* *sigh*

its okay man she'll get better as time goes by and plus 9k rpm is fun

the highest MPG i ever got was like 19...all highway baby. the elusive 20's...are elusive.

I just got 248 miles (14 gal) on my last tank. That has been the best I have been able to achieve to date. That was with a lot of high speed & rapid acceleration driving. If I tried an eco run....naaa.

wow. impressive number for sure. I only hope after break-in, I will get a little better number than 350kms (220miles).

nice! you can get really good numbers if it's pure highway and you keep it under 3800-4000 rpms. i think i got 24.8 one time with 90% highway.

not to potentionally burst your bubble, but are you running non oem tires/wheels. if your overall diameter is different then oem, it will throw off your "miles"...I THINK. not sure on this, but i think the trip and odo rely on that figure...so your numbers might be inflated a bit. someone correct me if i'm stupid :P

How fast were you going? And you must have had a big tailwind. :)

Oh yeah, what size tires/rims are you using like 2tone mentioned?

This thread reminds me of my wet dream from the other night of a 25mpg tank.

Sighs and thinks he is only getting 17mpg

J'te crois pas. :Eyecrazy:

Sti, j'ai de la misere a passer le 350km colisse.

Pas de farces! Trois-Rivières à Jonquière sans arrêt et il me restait presque 1/2 tank! Le compromis c'est que le cruise-control était à 105 km/h par contre :sleep: Je me suis quand même amusé de temps en temps à dépasser du monde à 150 km/h en montant les côtes :lol: Mais ça, il faut pas le dire à personne!

nice! you can get really good numbers if it's pure highway and you keep it under 3800-4000 rpms. i think i got 24.8 one time with 90% highway.


Exactly. I set the cruise-control to 105 km/h (65.2 mph) for the whole trip and I was running at around 2600 rpm. My driving was far from agressive. In fact, I did this to settle a 'bet' that I could not do the 350 km trip without refueling. I did it with just a click over half a tank. :ylsuper:

You're absolutely right. But I am still running my 18'' OEM Dunlops. They only have 16 000 km on them. So I guess the numbers still stand.

Man, you make me jealous. I hit 23mpg on a mostly highway trip from NY to PA, and I don't think I could improve on that too much more.

The OP must have been getting passed up by the minivan and Camry drivers at 65.2MPH. :)

65.2 mph @ 2600 rpm?
is that what the autos run at or am i missing something here...

yeah that seems low...

at 72mph we're at 3700rpm right?

What gas did you use? What oil weight?
I can hit ~480km with a full tank of gas in mixed city/hwy. That's about 12.5l/100km. And this is with redlining activities on some drives.

65.2 mph @ 2600 rpm?

My 04 manual puts me at 40mph in 6th at 2000rpm.

awesome!!! the one time i got almost 25 mpg was MOSTLY highway, but i definitely went above 70 a couple times. it's SOOOOO hard to keep it at around 65 mph!! ha ha, like caranddriver said i get passed by priuses and minivans and camrys and...well, everyone!! :)

so if i'm running 245/40/18...i know it's not MUCH of a difference than oem but it is a tad bit shorter...then my mpg record of 24.8 is slightly HIGH, right? shorter overall diameter = artificially high mpg? damn, i guess i can't quote that then, i'll have to figure out what it was and go for 26mpg...ha ha

I was driving just under 60mph and in 60th gear and was able to get above 26 mpg *just around 28 really*. I was so proud, but then decided that I liked reving it up a lot more.

Is this some sort of conspiracy your all in on! 400 km all highway the best I've ever gotten(100-120 kph). My average mostly highway in the GTA 320 to 350 at the low fuel light.
Is this magic or fringe science 8 don't get that kind of mpg! it's a rotary.
Please stop this madness, I've tried and tried to get better mpg, it just does not happen. I gave up a long time ago even trying. Just enjoy IT! IMO

haha^ awesome.

i only "try" to get good mileage on my drives from austin to dallas and back (about 200 miles each way). just b/c i'm never in a big rush and i like to see if i can do better than the last time. but around austin i don't really even think about it.

I got 280 out of my tank last week...
The first time that high...coz I got too many speeding tickets
never over 80...mostly 73 on the freeway
and some local
280 miles and still have some left...put around 12.7 gals
around22MPG....my best already @.@
26???? no way...

My 04 manual puts me at 40mph in 6th at 2000rpm.

...?
that wasn't my question :banghead::lol:

65.2 mph @ 2600 rpm?

2004 4 speed auto
3000rpm 73mph

Yeah I just started watching mine....14.97mpg it's just not cool at all. I was reading everyones averages in the 15-20 range and I'm falling just flat of bottom.

i know your pain

lol... when I first bought the car I was consistently getting 12-13mpg. Granted it was all city driving lol

Now, I get 18-20 mpg but most of it is highway mileage

I got 26~28 from my .....daily drive V6 MX-3 :ylsuper:
1.8 V6, smoked the 1.8 TURBO Jetta, hell yea!
93 1k car VS 03 10k car....my buddy almost cried, lol

Wow... I was actually going to make a thread about this. 50/50 highway city, I get about 23.7mpg :) But I was in a massive traffic jam and did a huge amount of short trips. I'm sure I can get more than 500km from our measely 55litre tank.

Filled up 52 litres of 91 Ultramar.
Using 5w30
I don't baby it. Daily redlines, pretty hard turns, etc. But I use cruise control on highway
Stock Potenza's... 225/45zr/18
6 speed manual
470km on 50 litres or 13.2gallons which is about 23mpg

Missing anything else?

EDIT: Forgot to mention that my MPG gets better everytime for some reason... when I first go the car I got exactly 19.5mpg, now it's going higher and higher. Maybe it's due to cleaning up all the oil in the intake?

The OP must have been getting passed up by the minivan and Camry drivers at 65.2MPH. :)

Lol! You betcha! But I didn't mind much.

Well maybe a bit.

Nah, not really.

Who am I kidding? I did cheat sometimes and passed them at 150 km/h (93 m/h) uphill, just to show them what my 8 was made of (and also to heal my ego somewhat :)) 'But it was all part of an experiment' lol

65.2 mph @ 2600 rpm?
is that what the autos run at or am i missing something here...

Yup! Finally, the ATs have something over the MTs! :lol:

Boy, am I gonna get flamed for this!

(Ducks and runs for cover)

I regularly get 23-24 mpg in steady highway driving, cruising at 70-72 mph (above 75 mph it falls off noticeably).

3rd gear is 1:100 mph to rpm so 30mph = 3000rpm. 6th gear is 1:50 so 30mph is 1500 rpm 65 mph should be 3250 rpm ect....

How are you canadians calculating MPG when you full up by the liter? And secondly, are you using an american gallon or the imperial?

I just don't see how a stock car gets anywhere near 26, even if the've got the cruise on 60ish.

Good point since I did not specify which one I used. According to this site http://www.euronet.nl/users/grantm/frans/fuel.html my 8.99 l/100 km equals to 26.2 mpg (US) or 31.4 mpg (Canadian). It really is confusing with all those different standards :Eyecrazy:

take whatever amount you fill up at the station / 3.785 = gallon.
(50L/3.785 = 13.21 gallon)
take whatever km your trip meter tells you / 1.6 = mile.
(350km/1.6 = 218.75 miles)

218.75mile/13.21gallon = 16.56MPG

Wow, I just realize my first tank of gas has better mileage than I thought. :) :evil_laug I was expecting 14mpg for break in period. :p

I grew up calculation meters and liters. But I found mpg makes more senses. :p

I think it's screwed up by using liters/100km (liters needed for 100km).
If they use kms/liter (kms ran from 1 liter of gas) would be easier to understand.
It's reverse of mpg in idea. :dunno:

Yeah... for awhile I was calculating imperial and I was like 28MPG?! How was that possible? Then I calculated it to US standards and was a miserable 23-24mpg. Going to try to see the best I can get.

A few weeks ago we took a trip to Cape Cod with two friends. Cruise control set at 72 mph, the Acura CL-S got 32mpg, the rx-8 got 24mpg and the 911, a 30 year old car with no cruise got 28mpg. So, twenty-something is possilble in the Mazda. You just can't have too much fun while doing it.

2nd tank of gas on my 6mt mostly city I got 17.5 mpg. It's getting better mpg than I thought it would be. :)
