My fuel economy seems like it is a lot less than it should be. a 4cyl jetta like mine should get at least 350 miles on a full tank but right now i'm only getting about 280 miles. I am going to try getting my spark plugs replaced and my tires rotated, but is there anything else I might want to try besides that?
what would cause fuel economy to go down on 1993 Volkswagen Jetta

New air filter and fuel injector cleaner could help.
thanks! i'll try that, and since i was contemplating on upgrading my air filter to a short cam eventually, this helps influence my decision a little bit :)
