I'm guessing that I probably burn a gallon an hour
probably more. JK, but if it were true it wouldn't surprise me.
I have a question. My Jeep either shifts into neutral when I let off the gas, or shifts into the highest gear possible without lugging the engine (so that I could be doing Idle engine speed at 40 mph). But Whenever I shift manually into neutral, the rpm's go up from 750 to about 1300 (at around 30) and slowly go down as speed decends. So would letting the tranny do what it's supposed to do be better than neutral to a stop? I think that once I stop at a red light I should shift into neutral to save fuel, but when coasting to a stop, I should leave it in Drive? I also coast farther in drive because my Jeep can Idle after coming from at around 20mph. (it's that 4 Liter I tell ya)
