Do you use up more gas by always keeping your foot on the gas pedal while driving?

Think about it this way.

Is it more tiring to run at a steady pace (keeping your foot on the pedal), or running slow, then sprinting to keep up speed, then slowing down, then sprinting again (coasting, then accelerating).

The answer is….given a perfectly flat surface, and ideal road conditions….you’d probably end up using more gas coasting then accelerating.

But I think the difference would be marginal.

Yes, let the car coast as much as possible. Less pedal less gas.

Give it only as much throttle pressure as you need to in order to maintain the speed. It will use more fuel if you coast only to have to accelerate back up to speed.

Instead of coasting, just use cruise control if you have it. It does save gas.

coast if you going downhill
but think about it this way
if yoru on a flat road
and you let it coast, the cars speed will go down
then youll end up just giving it more gas to get it back up to the speed where it was at

It is always best to drive at constant speed. The only time you would save gas by getting off the gas is when you are traveling down hill.

Even better use cruise control (if you got it).

That was the short answer – here’s the long answer and the explanation:

It is best to keep constant engine load – which is often constant speed. But when the car is climbing uphill or down hill, it is better to let the car slow down a little (uphill) or let the car naturally accelerate a little (down hill) – to maintain constant engine load.

On a flat road accelerating and then coasting will use MORE gas than keeping constant speed. The reason is that it take MORE fuel to accelerate than it save when coasting. If you don’t believe me, just know that car companies use cruise control when they measure their car’s MPG for advertising, etc. (where the best mileage counts).

Good Luck…

No, but it would save if you coast downhill or to a stop sign.
