3L Mileage
What kind of Mileage do you 3L guys get? And what kind of driving do you do to get what mpg?
Just curious I'd like to do a 3L build someday.

In all honesty, I don't care. I don't take it on long trips, or anything. It's a fun car, so I just fill her up and go!
I would assume tho that like with any car, it's controlled by your right foot. You could probably get 20-22 without issues if you were just highway cruising.

Ditto.... Who cares, if you worry about it, it spoils the urge to plant it and take it to +5000 and get the goose bumps.
FWIW Over 8 years I'm averaging 20.27. Month on Month: 16-23 depending on mood.

I can't comment on a 3.0 i4, but with good engine management and a light foot you should get pretty good gas mileage. I get about 23.5-24 mpg average out of my 3.0 litre i6 in my 530i/5 and about 30 mpg at 70-75 on the highway running about 3k or so RPM. The engine is a m54b30 found in e46s and e39s and gets roughly the same economy as the smaller 2.5l version of the engine.

Is there a reason to believe the MPG would be much worse? The horsepower requirements to maintain 70MPH are the same, and I'd tend to believe the MPG of even a modern V8 would be similar.... Corvettes can get 28-29 with the cruise on, not that its a direct comparison, but it does show that displacement and 400HP aren't the problem.

I'm getting about 17city/19hwy. Two things though, it runs rich (never finished tuning) and it has huge cams. The cams are getting redone in the next few weeks to a profile that is more suitable to my usage. The cam change alone, should add a few mpg.

I can get 23 or 24 city in my NA and just over 29 on the hwy.

I'm always amazed by my MPG. I can get close to 30 if I just cruise around. Even when I get on it around town, I still get at least 20-22. My car stays in closed loop targeting 14.7 other than when on heavy throttle.
