[QUOTE="frogslinger, post: 91121, member: 3117"] Shifting gears does not hurt gas mileage... running at high RPM does... if you can force the engine to run at lower RPM anrd higher load you can eke out about a 10-15 percent advantage on a modern motor... If you are familiar with GM vehicles the V8 manuals generally have CAGS which forces the car from first to fourth gear under normal conditions... this causes that low RPM high load scenario I mentioned. It may seem counter intuitive but the best analogy is this... if you drive down the highway in 3rd you are running at a lower percentage of engine output at that RPM but you will be getting worse gas mileage than in 6th... Down shifting does not help gas mileage it is only supposed to occur when the vehicle thinks that required output in a gear is going to be higher than available output in that gear. Gotta love torque multiplication. I think so. [/QUOTE]
