It's not just about rpm. You can be at 2000-2500 rpm and still take 25 seconds to reach 30mph by barely touching the gas, but you are wasting fuel being at a higher rpm than you need for the power needed accelerating that slowly. The gas almost all the way down at those rpms is usually the best. Good acceleration rates then depend on engine size and car mass. (Usually about 8 seconds to 30mph in a small 1.2 litre car)

It is better to use low to moderate rpm but actually be generous with the accelerator pedal. The engine needs a small amount of fuel to fight its own friction, and the rest will turn the wheels. Being generous with the accelerator makes the fraction turning the wheels relatively larger. Lowering rpm makes the fraction fighting engine friction lower.

As long as the car isn't shaking from trying to accelerate at 1000 rpm that is.

I think the Scan Gauge is a great tool. Too bad it doesn't work if you own a '95 or older car like I do. We are just SOL.

I have a 94 Integra and the shift points in the manual are at about 3000rpm, I shift up at round 2000-2750 rpms, am I really hurting my gas mileage? You said to go by what the manual says, in all the cars that you have seen, is this really the best thing to do? Thanks! -Aaron

I can't live without my Scan Gauge II

If the delay on the scan gauge II is too slow just increase the rate in the more>more>rate screen to "fast."

Good video and recommendations, I'll try this.
