MPG on your e30?

[long tall eta]

my eta with 3.25 lsd and a chip and 400,000 on the clock still gets 29+ on the highway and 24 in the city.

Back when my car was an M20b25 I would consistently get 25MPG no matter how hard I romped on it .

Now with the s50 I can only get 22MPG mostly highway . I got 25 on the way to H20. Doesn't matter what I do. Changed out the diff to a 2.93. Same mpg . Put a new 02 sensor in , wasn't running one at all, same MPG. Ran a hotter thermostat so it would actually sit at operating temp. Same MPG. No vacuum leaks. Think it might be the racing dynamics chip from 1997. :/

I hit 30 while doing only highway with my turbo m52. Around town with a little highway I hit 19, but it's hard to keep my foot out of it obviously lol.

same... 31MPG M52 turbo on highway driving conservatively.
1/2 a tank an hour driving like it should be driven

Ehh I drive a bit aggressive, usully about 23mpg 40/60 mixed driving. And about 27 hwy at ~80 mph. M20 318is with 5sp/4.10 diff and m30 afm, 19lbs injectors, ebay chip and catless exhaust.

Vert gets 26 hwy@ 70mph with top down and screen up. Autotragic, 3.73 diff, and 19lbs injectors and ebay chip.

M30B35 manual e30 with 3.73 diff.

City: 13L / 100km (18mpgUS)
Highway:??? ... only recently fixed my odometer gears and began tracking mileage.

Strangely, the city mileage is slightly better than when my car was a 2.0L M20 automatic!

With my old eta i got about 20 city 27 freeway.

I got 25-27mpg in my m30b35 with a 2.93lsd going to Gfest '13. I went to a 3.25lsd and I am not too sure. Roughly mid 20s is my best guess. But I did not build it to get mpg, I am lucky to get 15mpg haha.

[serdar255]

Im scared to calculate mine. The 4.10 diff and a light weight flywheel make it intoxicating, I cant keep my foot out of it.

Forgot to mention its a 325i basically stock m20 just chipped.

[BMWManiac]

With my stock M20, mostly highway, I was getting maybe 23.....I don't know how you all getting 27+ on a m20...driving 65 mph?

I thought turbos helped fuel economy! All they seem to do on E30s is trade it for one of these > :D

[MR E30 325is]

I was able to hit 34.0 MPG on a road trip once.

Around 30 highway only is commonplace.

Around town is far less, usually 19ish, due to a heavy foot and a desire to enjoy my built E30 to the fullest.

[enigmaticdream]

On the 325 - 4.10, chipped, cammed. I'm getting around 21mpg city and probably 24-26 highway.

M3 - 17mpg or less city and 26 highway? I beat the shit out of it driving around the city.

[TheTacoMan]

When i had a stock auto seta with a 2.93 i was getting 30-33 Freeway, thats now 21ish with a turbo.

I hit 30 while doing only highway with my turbo m52. Around town with a little highway I hit 19, but it's hard to keep my foot out of it obviously lol.

So as an update, I've stopped trying to hard to hypermedia because it's worth it to have fun when I drive. My average now floats between 25 and 28mpg combined.
