So about a week ago I bought a 2001 civic ex sedan. Next day I filled it up and reset the trip odometer. We changed the air filter and oil I did notice it had a after market gas cap. I filled the tank up again today and it took 11.6 gallons and the trip odometer read 155.2 miles working out to 13.3 miles to the gallon. I went straight to the Honda yard and put a Honda gas cap on any ideas on why the MPG is so low?
