I've no idea why my fuel economy has tanked.. I'm getting average 17 mpg. All tires properly aired, air filter clean. *shrug* I drive 100 miles/weekday to work and about 100 on the weekend total. I'd say I do 80% highway driving. I do tend to be a bit skinny-pedal happy though, lol.
Sounds like your having some issue. I just changed my upper and lower arms with new bushings and balljoints, and added a performance dry air filter. I now get 21.7 city. Last night driving home from work (8 miles), once I got on the hwy I reset MPG, cruse control set to 65mph, I was getting 28.3MPG! No...its not down hill all the way home. Iv seen as high as 33MPG going to work at same speed.
