I have a 2005 Acura Tl and my sister has a 1998 Mitsubishi mirage DE at. Im currently with my gas guzzler..lol but as soon as I sell it i will be on the lookout for and Honda civic hx! I have a question if anyone here has tested it. If I run regular in my tl will gas mileage stay the same? I drive very moderately and dont even hit vtec anymore so regular should be ok but before i make the jump i'd like a second opinion
