It falls out of the equation, so it's a factor.
Standing still, yes, BUT in my 1993 Chevy van I can get 100+ MPG down hill out of gear with the engine Idling...and have done it.

I say my van as IT WILL let the motor idle out of gear at speed which my Ford will NOT..out of gear the engine RPMs are higher that in gear at the same speed, what is up with that??
