Question I've wanted to ask for many years. On either a engine with carbs of Fi, the story about saving fuel is less RPM's less gas used. Now lets take a 5 speed manual tranny. Going down the road at 60 with rear gears of 3:00(just an example) your turning around 3200 RPM's. You shift to 5th gear and your RPMS drop susposely to save gas. What happens when you come to a hill and you notice in that gear that you loosing speed and you give it more gas. Now my question is if you don't downshift to 4th gear, your going to be using more gas trying to get up the hill in 5th. Right or wrong. Always open to commemts.
