That's what I was told but when I look at my gal/hr with 0 throttle it is still ~1.xx with instant MPG not super high. When in neutral, gal/hr = ~.25
Does anyone know of a good way to test it?

I was thinking the same thing as well so I tried to not be in manual mode and was not able to see my gal/hr go to 0 with 0 throttle. I am going to try it on the highway on my drive to my in-laws tonight and see if it depends on the RPMs. Also my trip MPG sucked this morning driving in automatic mode
