I ran 80-85mph from Florida to S.C. and averaged 17.8mpg's, all this was done running 87 octane with the a/c running constantly. My truck is still bone stock unfortunately.
Forgive the question, Im still new at all looks like we have the same truck and correct me if Im wrong but you limit the tranny to 5th gear around town and leave it open for highway driving?
