Engine Braking and Fuel Economy

[Chills]

Without reading any of these responses I will say that I tested this out the other day.

I filled up my tank and then reset the onboard computer to check my MPG.

It is only 1/2 a mile from the Shell to my house so while driving home I blipped the throttle when downshifting and braking and I watched as the MPG numbers went WAY down. It was 19.2 and dropped to 15.4 by the time I made my final turn into my garage.

When the RPMs go up the MPG goes down.

As a general rule, I've been following the "coast to a stop" philosophy. It seems to make much more sense to me to have the engine at idle as I coast from say 30-40 mph than to have the idle at at any other RPM. I also think its fun to see how well I can use my momentum to use the brakes as little as possible to come to a stop. This requires you to look far ahead as possible which is a trait you need in motorsports so its kind of putting theory into practice.
