Well you do say you pretty much do only city driving. So, I would not expect to see the average of 29 MPG. Also, I have always heard of the break-in period, that may also apply ? Remember, those numbers on the paper are under ideal conditions, which none of us drive in. Have a look in the forum under the mileage section to see what the real world numbers look like, posted by us average drivers. My wife drives more city than highway and is averaging 7.9 L/100kms which is about 31 MPG (US Gallon).
