If I put my car in neutral during a traffic stop and put in back in drive when I moved, will it save gas?

If the car is running either way, I doubt it. I suppose you might possibly save a tad by shutting it off at a long light.

no, it will still idle at the same rpm. turning it off may save gas but when you restart it that will use the gas you saved.

Hardly, it will work harder and use more fuel when in gear, but very little difference.

Forget saving gas, think about your transmission. A rebuilt transmission will cause more than ten gallons of gasoline.

Automatic transmissions were designed with a torqe converter that requires you to raise the revolutions of the motor before it applies the gears in the transmission. Because of this, it’s like being in neutral automaticly. So, no, this isn’t necessary.

no and when you go to put it in gear you might put it in reverse and back into the guy behind you that wouldnt save you any money would it

I really don,t think you would save any gas at all because when you are stopped at a light your engines R.P.M. is always lowered. The best way to save on gas is to keep your car in top mechanical shape by having it serviced on a regular basis

Doubt you will notice any increase in fuel mileage..but if your stuck in traffic its not a bad idea to put an automatic transmission in neutral… torque converter slippage causes heat buildup in the transmission…just don’t forget to hold the brake and put the transmission back in drive before you get on the gas…

If you did it wouldn’t be much.

I don’t think that you would ever find out the difference with out test equipment.
