I'm averaging 22 highway 19 city driving. I'm curious to see what the average mileage other drivers are getting and curious as to what type of things I can do to better my mileage. I drive a 325i 06'. And I almost always drive in the manual mode. I don't enjoy my driving experience quite as much using the regular drive or sports mode I drive about 60 miles a day highway and 20-40 city , 5 days a week. I heard rumors that the charcoal delete mod may have a positive impact on MPG. Anyone have any experience with that?

I've seen 33 before highway. Weather was bad so I was traveling about 65mph instead of my normal 80. My average is about 26. I'm very pleased with my cars economy.

OBC indicated that I averaged about 31mpg on the freeway, mostly doing 75mph on a 3.5 hour drive. Around the city, I'm lucky if I get 20mpg. Usually hovers around 18-19, and I drive pretty normally. I don't race or dart around traffic.

I average about 27-30 MPG, but then again I live and work close to the freeway and set my cruise control so that the car figures out the best mileage for me.

I get about 15-17 in the city and 26-30 highway, depends on speed and how frisky I am that week.

Also I don't know about y'all but my computer amount is always about 1.5mpg lower than reality (by dividing miles driven on tank by gallons filled). Not sure if any one notices that too but I ran a whole tank city last week and got 14.9 on the computer. Yikes.

Fuelly usually has a good aggregate of MPG statistics that will give you a general idea of how well you and your car are doing.

This is me
http://<a href="http://www.fuelly.co...ddanj/330i</a>

Over 16k miles I've averaged 26MPG with the the highest being 32MPG. I use the old miles per tank method, since I've found the onboard MPG calculation not to be accurate.

If you are getting unusually low MPG, could be several factors -
Car issues - dirty MAF, dirty air filter, maybe vanos or 3-stage intake flap issues
Driver issues - heavy foot, etc

Hope that helps.

Interesting reading you guys' posts on this. Didn't appreciate how well-off we are in Europe with the direct injection N53 engine. I never get less than 30mpg overall and on highway runs 40+. On a run, I get great range - over 550 miles from a single tank-full...
