Ar 110 MPH my Rpm is 2500 i have an auto 4 speed . Hey yellowx if u went 610 KM on 50 l thats 34.3 MPG preety good for that speed u where going , I dont speed too much with the kids in the car and i was in a 90 KPH hyw. so at 110 the coppers dont bother u ,so far so good. Airknight i dont like the metric system for the milage thing. MPG is a universal way we all know how to figure out. U have to keep your speed constant no fast stars on the hyw. if u want to get better milage have fun cul Jeff

Hope to c u all at a meet this summer
