Gas Efficiency at Highway speeds. Engine Condition
i was trying to figure out two things, first what would be the best speed (or RPM) to have the engine at to go the farthest while using the least amount of gas.
Second, by the #s below, can you tell if the engine is in good shape?
(Taken in 4th gear)
2000 RPM = 49 mph
2500 RPM = 62 mph
3000 RPM = 74 mph
3500 RPM = 85 mph
