Whats your tires profile? Since you have 17" wheels, the odometer might be off a little.

I get around 8mpg running E85.

[M-technik-3]

28.5mpg 332is with a 2.97LSD just hate the rest of the E36 BS

Pay no attention to my post didn't see the M30 remark

I pull about 15mpg in the B35 e28. It's got a clogged cat.

Mixed I get about 15-17mpg. Freeway only IIRC just about 22.

^speedo will read 1.7% faster then what you're doing.

Maybe change to a longer diff.
The odo stopped working but on the freeway, or long cruising mine sips on the gas.
2.93lsd

I already tried the 3.25s, it would be perfect in a coupe or sedan but with my car being 500lbs heavier the extra gearing really helps.

How in the hell are you managing above 27.5mpg? In my S50 I pull just 27.5 and I thought that was amazing. 28.5 is incredible.

I've gotten between 19 and 24 with every engine I've had in this car: m42 got 24mpg on good days, 22mpg average. M30 got 20ish usually and the m60 gets a steady 19mpg. Thats about 50:50 mixed city and highway. On trips to far away shows with the m60 I get 26mpg cruising between 80-100mph.

gears + tunning you might see 20 with cruse control but that is about as good as it will get.

Why the fuck did you downgrade to M1.1? Not trying to be a dick, but c'mon, seriously... why?!?!?!

A 4.10 diff on an m30? That's your problem right there.

He did not downgrade, when he purchased it that is what the guy had on it. He is working on upgrading it to 1.3.
