Highest MPG anyone achieve?

[88SuperETABD]

How are your guys's so high. The highest I've achieved is 25 mpg and that was on the 5, that was on the obc, which is pretty accurate. Cuz I normally double check it manually and its within +-.3 mpg. I'd say I average 20-21 mpg. Maybe its the way I drive, but even babying it and shooting for high mpg, I still only achieve 23-24.

2.7i, 272 cam, alpina chip. 3.73 LSD. getrag 260

Easily get 24-26mpg with normal driving/some hard accelerations. 22-23mpg hard almost all every acceleration.

Commute to work every day 50 miles round on I-75 75mph - 85mph depending on traffic patterns...I have the stock '86 ETA engine/intake/exhaust other than a turner chip.

I believe if I were to drive as if I couldn't afford gas then I could get just over 30mpg. This would involve going 65 or 70 on the interstate though. I'm not sure if the "govt. MPG gauge" for the car was based on 55mph highway speeds for 30mpg. In that case I could go well over 30mpg! http://www.fueleconomy.gov/feg/calcu...lumn=1&id=1752

BTW this is FL driving, no hills other than overpasses.

There's nothing wrong with the OBC if you haven't monkeyed with anything

anyway, I got well over 26mpg with my auto 325ix on a trip over to Lake Chelan. I got an easy 30mpg in a total POS 318is.

I wish my ix could even come close to that. I'm happy at 22 with easy highways. It's stock M20 with 3.91s

the new EPA guidlines, for older cars, are hilarious. I average 18mpg (epa rated average for a *stock* 325ix) with a stroker, 4.10s, R-DOTs and hitting 7500rpm every day - but if I cruise easy on the highway it jumps back up into the mid 20's from 45-70mph. even my city mileage is way better than they (re)calculate. It says a '91 325i averages 15-18mpg - but I get 12mpg on a racetrack!

best I got was with my Eta, close to 28 mpg, Most of the time i got 26-27mpg, once i made it drop to 23 with hard driving.

Currently, 2.8i (M20) G260 3.73S getting about 19-20mpg....Damn i need to tune this thing up

[Kershaw]

24mpg in my is. (gone)
29mpg in my eta. (gone)

absolute best (65mph for 30 miles) in my rx8 was 24.5mpg. i had truckers honking at me. haha. i usually average 17-18mpg.

what could possibly be the cause of semi-bad high gas mileage?

32 is the best I ever got. Currently I am getting 17mpg HW in my e24 xD

[MR 325]

Shit, my turbo car will average 18mpg on a tank of mixed driving!

S50 car, can't remember what it gets. LOL.

[5Toes]

My car going from my home in Bremerton to Naches WA (right off HWY12 and only a few miles over the pass) got 27mpg. Gas pump confirmed

I was driving fairly quick with my Mom aboard... and then I tell my Dad and he goes (28mpg isnt that good son). Stupid Dad..

My 525i e34, 19 mpg mixed up to 27 mpg on freeway. Going 50 mph on I5 to Everett got 31 mpg once.
My 1990 325i, unlimited, its electric.

[xxla81xx]

Mine gets like 10 mpg ='(

[bastianshaw]

33mpg 89 325is chipped. 60mph cruise= economy+ morre time in your e30:-)

In 2004 a buddy of mine used a mpg meter on a e30 m20 turboed at around 5 psi and made many miles runs after runs till he managed the sytem on low boost right and got 48 the key was to drive like a normal daily drive or like "Driving Miss Daisy" never runned it hard but consistant. Not bad but I drive hard at times.. not for me :(
