    Took my first long road trip after my valve job. I was surprised. 18.56 MPG!!!!
    drove 539 miles and used 29 gallons. Kept speed below 70 the whole trip(hard to do!).

    That's pretty good..... I just had mine to Florida and averaged 15.0 for the trip... I didn't try to keep it under 70 plus ran the AC most of the time
