Ok here is the Situation:
You car gives 30 Miles to a Gallon at 70Mph. At 70mph ( last gear ) you are in the middle of your powerband. The distant you have to travel is 33 Miles. You have only 1 gallon of fuel in your car. What do you do? Do you slow down your car burn less fuel? OR do you speed up? All road and air conditions are ideal. |

not really depending on speed and gear and the powerband of the engine maintaining low rpms is harder, requiring mroe throttle work and putting more load on the engine the result is burning more gas even though you are at a lower rpm get a vacuum gauge and hook it up. then maintain 2000 rpms in fifth gear, look at the reading on the gauge, then try cruising at peak torque and look at the gauge. the closer to 0, the worse the mpg, cruising at peak torque makes it very easy to maintain your speed, which means less work has to be done by the engine, which equals best mpg you can get. -------------------- 1994 Celica GT4 WRC Edition
