The last gear..... how long are you in first gear when you drive? Like 3-5 seconds..... veruses last gear which is 90% of your driving time.

Both. It completely depends on the revolutions per minute of the engine and the final drive ratios of the respective gears. Attempting to start from a stop in last gear will consume far more fuel than actually starting from a stop in first gear. Travelling at 15 - 30 MPH in first gear will consume far more fuel than travelling at 60 -70 MPH in last gear. Gears are usually referred to from low to high instead of first to last, as well.

The whole idea behind driving is to get from point A to point B. You want to do it in first gear? The engine is at high RPM and you do 20 MPH .So it will take you 5 hours of high engine speed to do 100 miles.
Last gear, if the engine was doing the same high RPM you would probably be doing 80 or 90 Mph. so in little over an hour you have done that 100 miles.
1 hr running the engine vs 5 hrs running the engine.

First gear

It depends on how high the rpms are. An engine is working harder in first gear at high rpms than last gear at low rpms. Thus you use less gas if you’re going 30mph in second gear then in first gear.

I would think the lower gears would because you use more rpms which needs more accelaeration! I'm not sure its only a guess. sorry if this doesn't help.

YOUR FIRST GEARS USE THE MOST FUEL.WHENEVER YOU GET OUT ON THE HIGHWAY YOUR CAR USES LESS GAS.
