After I got my M3, I did drive it a little hard but I still put some highway miles on it every day. I knew the M3 was a pig but after seeing mileage posts here, I wonder if my car has an issue. This is what I have for records since I got it:
I really hope that after changing to Alex's tune I can get some better mileage!!! When people on here post, is it in US or UK gallons typically?
That, or I need to invest in oil futures...
