Almost all of the milage is lost in the take off. Cruising at 2000 or 2500 rpm does not have that much of an effect as one thinks. Maybe 1mpg. But having to be the first one in the pack from a red light drastically reduces mpg. Do NOT engine break. Put it in neutral and roll to a stop. Let the old ladies pass you from the red lights.

I have a car that was getting 15mpg by the previous owner. It is now faster and gets 22mpg! The car has only gotten upgrades that would have made mpg worse. It's all in the driver. Learn to take off smoother.

Also, you can actually get better milage with a 4.30 (maybe even the 4.88's too) over the 4.10. The higher (numerically) gear allows you to use less throttle with the lower ratio to get going to your cruising speed.


I also had an F150 that got 20mpg that was originally getting 13mpg. And a full weight 12 second T2 that got 20+ mpg.

Ps. Weight is a killer! make it lighter!
