I purchased a used 2009 EXL coupe w/navi in Jul 2013. After a half year drive I just feel that the fuel consumption is higher than expected. I live on Long Island and commute to school 5 miles one way everyday. I drive mostly on Nesconset Highway which has a 55mph limit and several traffic lights, and also some local roads with stop signs. I hit the gas gently most of the time but the factory installed calculator shows that the mpg is around 19-20... Isn't that too low for a 4 cylinder accord? I remember it should be 21/31 or something. I tried calculating the mpg by dividing the miles driven between two fuel top-ups by the number of gallons for the second top-up, even worse. I did the 4-wheel alignment and checked the tire pressure and everything was fine. Is this normal?
