what's your m30 mpg?

[E30SPDFRK]

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.

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

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 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.

^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.

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

I just filled my tank for the first time this season... ouch! 15.7mpg lol.
