Sorry to bring up an old thread, but over the last 4 weeks or so, i've seen my gas mileage drop from around 27-28 MPG (city and highway) to 21-22 MPG (same thing)
I've had the car for a little over 2 months, and i've changed the oil, oil filter, and air filter. I'll be checking the plugs in a couple days, but does anyone else have any suggestions? any reason i'd see a decline this quickly? (admittedly, i might be doing more city than i used to, but i shouldn't see THAT much of a difference, should i?)
