2005 3.0i 6-7 City MPG??
 

I reset the Board Computer the other day to refresh the average consumption and after about 20 minutes of city driving i was getting around 6-7 mpg. this is with alot of stop and go (NYC) and it's just very very bad.. anyone driving in nyc getting this bad gas mileage? and i don't rev it high either, try to keep it under 2500 rpm....

Don't trust the OBC, measure mileage by filling up the tank, reset odometer, drive, fill back up at same tank and divide miles over gallons.

It depends how u drive. Im in NYC all my driving is city
And I average 11mpg driving spirited and
About 12.5mpg normal. If I do a highway trip
Its usually 15-16mpg. I done a full tune up
And no change in mpg. The e53 are gas guzzlers.
They are amazing to drive thought.

11.2 winter fuel sux. But I have 4.8, and speed it up usually.

i put 93 over 91 octane as it lasts longer.
And i find the cold weather to have a toll on mpg. seems to be a gas guzler. without warming up the car (idling puts wear on the engine) and tapping the acceleration. very slow keeping it at low rpms.

but when im in a hurry and driving like a F1 driver or the sterotypical BMW owner. I see the gauge go down really fast! like around 30 mile and 1/4 tank is gone!

I cant make my 550i do that bad in full rocket annoy everyone mode, and that thing loves gas. You got something wrong. That is a spectacular engine, My old E39 had it. Around town in traffic was easily 18-20. Highway 29. Vacuum leak, DISA, MAF, and/or pre-cat O2 sensors. Probably make a world of difference.

I'm the opposite. I have a 4.4 and with the cold, seems like my fuel consumption has decreased. :dunno:

I keep track of my mileage by keeping an excel spreadsheet. Here is a snapshot of a few fill-ups, 93 octane, E53 4.8iS, mostly highway miles:

At what speeds?

An easier way to track your fueling instead of managing a spreadsheet: Fuelly | Share and Compare Your MPG It won't have all the info you put there such as current mileage on the car and best works if you top it off etc..just an fyi
