Downhill all the way, with the engine shut off?

FWIW, you'll get best mileage by running EFI leaving it in gear going downhill. Most EFIs (oem at least) cut off fuel above a certain rpm during decel (1500, depends). Letting it idle uses fuel.

Joe,

Great report. I have thought I could get better mileage if I always went down hill. I am thinking about raising the air bags and putting smaller wheels in front, so I am always going down hill. *smile*
