When I am on a long downhill stretch of road I like to put the car in neutral; it saves gas (especially when the tank is almost empty) and I like to do that. I have heard some negative feed back. Do you think it is alright to do this?

What year is your car? Unless it is very old, putting it in neutral (and leaving the engine on) takes more gas instead of saving it. In gear, the transmission turns the engine, so no fuel is injected. In neutral, fuel is injected to keep the engine turning.

It’s not alright It’s often illegal You are not saving any fuel, and are more than likely increasing fuel consumption Also fundamentally, if anything, even if you were saving fuel, you would see the most benefit with a full tank, since the added weight of the fuel would enable you coast a couple …

No, it’s not alright, and it does NOT save any gas. None. Zip. Zero. Zilch. Nada. In fact, if your car is fairly new it uses MORE gas in neutral than it would if you left it in gear. Modern cars are programmed to shut off the fuel injectors under these conditions, so you use ZERO gas in gear …

If you make a habit of driving around with an “almost empty” gas tank, you will be replacing your fuel pump often. Very low fuel levels cause them to run hotter (less gas to cool them), and to pick up more trash.

Not a good idea. If you drive an automatic transmission there is a chance you’ll go past N and into R for reverse. This can damage the transmission. In a manual you can’t harm your transmission but it dosen’t save gas, unless you actually turn off the motor as well. Since that would be dangerous…

Here we go again. There is a search button at the top of the screen. Please use it.

Isn’t this like the 17,846,452 time this question has been asked? I think we should just quit answering questions that have been repeated ad-nauseum. If you don’t feed them, they won’t grow!!

Except for a couple of Fords that I’ve driven, there’s no need to push the button on the shifter to go from D to N. Said button is meant to lockout N to R shift.
