Im still getting used to the car and i wanna try n figure out the best way to get the best gas mileage, where i live its mainly 35 mph everywhere, n @ 35 overdrive will kick in if its on n go down to 1100 rpm or so, where as if overdrive is off i will run about 1500 rpm or so. In theory the 1100 rpm would get better gas mileage. But running that rpm would that put more strain on the motor working it harder so it would burn more fuel??? Just a though lemme no wat u guys think
