(i drive a manual) Is it more cost effecient to drive at higher or lower rpm's?

Answer 1

Yes it is more cost efficient to run at lower rpm, the less rpm you are running at, means your pistons aren't pulling as much gas, as an example take two people with the same car, person (A) is constantly shifting at 4000 rpm or more, and person (B) is shifting at 3500 or less, person (B) is likely to average 50 to 75 more miles per tank of gas.

Also running at a lower rpm reduces stress to the engine, transmission and all the other little parts that cost a fortune to fix, and your oil doesn't break down as fast.

Answer 2

It's always more effecient to drive at lower rpms. It's best to shift as soon as you can, but you can pick up speed faster at higher rpms, but it guzzles gas.

Answer 3

Definitely at lower rpm. Imagine your engine running at about 2000 rpm and the vehicle is going at 100kph. Noise level of the engine is also lower and save fuel too.

Answer 4

Well...what do you think would suck down more fuel? An engine running at 2000 rpm's or one at 6000 rpm's? If I had to SWAG it, ( Scientific Wild *** Guess ) I would go with the one at 2000. The high rpm motor would requie a higher fuel flow.

Answer 5

It is more cost effective at lower rpm's, you save fuel at higher gears, which translates to lower rpm's.

Answer 6

generally towards the low end but if too low causes increased gas usage the rpm gage has green yellow and red markings most of the time .Keep it in the green.

Answer 7

Try and get into top gear as soon as possible. That is the most efficient way to drive.

Answer 8

if its tuned right,its easier on gas then a automatic.
