My father and I have a long going argument. He says that while the car is in overdrive you save more gas. I say the opposite, that the car is burning more gas. Maybe you have something that I could email to him proving that I am right If you do I would really appreciate it.
You are suggesting that the car is burning more gas in overdrive? I am sorry, but you are incorrect. Please consider, for the sake of this argument, overdrive to be like a fourth gear. the engine revs at a lower speed while the car goes faster. Overdrive was designed for the simple purpose of saving fuel.
