I call BS on anyone who claims 35+ MPG on a petrol engine for "city" driving. If you are getting those type of numbers, you must not be stopping every couple of blocks for traffic lights or dealing with lines of traffic. I have a 2.5L I-4 and spent an entire tank driving while keeping under 2000 rpm for shifts while driving to and from work in Atlanta. I got a whopping 21.3 MPG. I then spent another tank driving aggressively from light to light and got 19.6 MPG. Even my 1991 Prelude Si with a 2.0L I-4 did not do any better than 22 MPG in the city. Now cruising on the highway at 75 MPH in 6th gear, I can pull 30 MPG... but that's much different.
