My experience has been the same as Guenter's Roger987 - Monday, 16 April, 2012, at 8:08:33 pm |
You're missing the drivetrain inefficiency Boxsterra - Tuesday, 17 April, 2012, at 9:57:19 am |
Yes. One must have a greater offset to mpg than the other. Laz - Tuesday, 17 April, 2012, at 11:28:38 am |

And auto stop/start while coasting would maximize the mileage, albeit weird.

Let's disconnect those, then. *NM* Laz - Tuesday, 17 April, 2012, at 7:58:11 pm |

On a steep downhill 2 mile stretch near my house I usually reset the mileage for fun -- I keep it in gear. It usually goes to 99 mpg!

I would love to have someone explain what I experienced to me. I had seen the posts saying no gas is used if the car is in gear but then I just don't know how I experienced what I experienced. Anyone have an idea how I got what I got?

I thought of those but if I am driving as I usually would on the whole trip except for the downhill section with the weather being a nice day with nothing out of the ordinary, and I was coming back from a track weekend so the car is a bit loaded more then usual, and I must have had the top up because if it was down then I would have gotten even better mileage. I guess I could have had a tailwind but there was traffic so I would not think it would effect my mileage any appreciable amount. I do understand these things and thought of them but there was nothing out of the ordinary. Going home from a track weekend I would think I was driving more "enthusiastically" but maybe I was driving easier. I guess I need to do another experiment and see what happens.

and was going home from Vegas to L.A. and there is a stretch on the 15 that has about 5 mile(?) downhill and I would usually average around a 21-22 mpg for highway driving, but this time I put it in neutral going down the hill and it rose my trip avg from 21-22 mpg to 26 mpg for the entire trip. The only explanation I could think of is that since the rpm is about 800 at idle and if I was in gear it would be about 2500-3000 rpm. So the engine was using less gas when the engine does not spin as fast. I was under the assumption that if the car is running some gas is always fired into the cylinders, regardless if there was any load on the engine. This is all anecdotal but I have noticed my mileage increase doing the same sort of driving in my other car as well.
