[QUOTE="Anybodyhome, post: 428159, member: 19161"] Your MPG will also be effected if you have larger tires and have not reprogrammed for the new diameter or you've added weight with those tires and the spare. There are a lot of variables here- auto versus manual trans, wheel/tire size & inflation, vehicle weight, gearing, etc. FYI, I once got close to 20mpg.... downhill with a tailwind.... [/QUOTE]
