well last Saturday I took the plunge and picked up a pearl white '05 GXP with 67K mile on the clock. In excellent condition but I'M still very reserved at what I can expect over the long haul and a little disappointed with the current highway 22-24 MPG (as I have a fairly light foot).
Just started on the little things i.e cleaned up the IAC, new air filter(original was filthy), inflated the tires to 38lb front and 34lb rear (originally 30lbs in all 4). Don't know whether the original owner was running dino oil or synthetic but was considering going with a 5W-30 synthetic oil.
I was kind of curious whether anyone had found any secrets for getting a little better MPG out of the GXP'*? My target is a consistent highway 30MPG or better
