Hi Anthony, Just a heads up on my Honda. Jane and I made an overnight trip to Ocean Isle Beach for a wedding. Left Saturday, came back this morning, a 400-mile round trip on one tank. Before the fluid changes and tune up I would get 25-26mpg on the highway. This trip I got 33.5mpg running 75+mph with the air conditioner running the whole way. I am a happy man! Kudos to your pit crew.
