Fuel Econ for N52
Hey got a question, I have 11 328i xdrive auto. I am not sure if this is normal but iam avg 17 mpg (this is about 90% city). I thought this was close to normal but its getting pretty much the same as my M. The plugs were changed in jan and I use shell 91 gas. Whats everyone else getting ? I feel that this isnt good mileage, is there any thing i should look at to improve mileage?
FYI
Tires have been swapped to summers not much improvement
No CEL.
