: That does seem logical, but maybe its not designed to give an accurate readout in neutral. Why were you cruising in neutral anyways. Just to let you know, it is Illegal, at least where I live to drive your car in neutral unless your foot is on the clutch. Obviously nobody would know that your doing it, but its a safety law so you are able to get out of the way of any trouble quickly without having to step on the clutch and put the car in gear.

: : Ok, maybe I just have NO IDEA what the hell I'm talking about when it comes to car engines, but I've noticed a strange behaviour. Say I'm driving @ 40 MPH. I take it out of gear, and leave it in neutral, so it's just cruising and idling. I would think that the mpg needle would show the top, because I'm using just enough gas to keep a 700 RPM idle and going like 40 MPH, no? It doesn't. It is high, but not at the top. But if I have it in gear and just let completely off the gas, it DOES go to the top (highest MPG, no actual #). Why? Isn't it using more gas to maintain, say a 2500 RPM idle (if I leave it in 3rd) than a 700 RPM in neutral? So shouldn't neutral, 700 RPMs give me better mileage? I just find this really strange... can someone please explain this to me?!

: : Thanks!
