Since I put a lot of miles on my car during my daily commute, I've been trying to maximize the mileage by driving fairly conservatively. Here's the interesting part though... if I punch it every so often with short bursts of speed (like for passing -- 85-90mph), the mileage actually improves. For example, my navi might be reading say, 21.7 mpg for awhile (roughly 75mph average on fwy), but after the burst, it jumps to something like 22.3mpg. After awhile, it might drop back down, but with enough consistent bursts, I've been able to keep it higher. I'm currently averaging between 23.7 and 24 on this latest tank.

Mine does the opposite, as I believe it should. Don't know what to tell you Ken.

I recently just got past my break-in period and floored the car constantly for the last 1/4 tank. Just filled up today and I got the best MPG to date, 20mpg. [dunno]

I don't suppose you guys bothered to make note of the mileage before the most recent tank, after and the amount of fuel you put into the car? That would give you a TRUE average you could compare to the Navi. I've heard complains that it's totally off.

I've been doing that just to make sure the navi is accurate. So far, it has been.

he he he i thought i was wierd

got mine on 3-26-03 and have the receit from Mobil for every fill up for the 2000 miles I got on it. All i need to do is analyze them like you did.

i wanted to not worry my pretty little head about such serious things :) for a little while anyways I do 500 Miles a week commute but i only drive the G on 1-2 day of the week as a treat to myself.

Lies, Tricks, Deceit!

As stupid as this might seem, one of the reasons I broke down and got the nav was because I was sick of doing all that manual math.

Hey Kloh,

I noticed the same thing this morning. I started out at 23.2, but since I was running late this am, I was pushing it a bit. When I got to work, 50 miles later, I was at 24.9. Half of the ride is highway, but I think it might be more due to gear selection.

When I'm on an economy run, sometimes I may skip a gear when shifting. I don't think this is helping because in the higher gear, at a lower speed, you are forced to use more throttle (and more gas?), to attain the same acceleration. When you are running thru the gears normally, you are using less throttle and perhaps less fuel.

Make any sense?

I think gear selection does have a lot to do with it. I also wonder how much the "intelligent" transmission does. About all I know is that it supposedly adapts to your driving habits and shifts accordingly. [dunno]

That's the truth! Mine goes to 6000 RPM before shifting almost every gear. I've trained her well!

Mine likes high RPM ranges as well as Lead's but sometimes she likes the feel of domination, in which I happily use manual shift mode.[}:)]

Proper gear selection for fuel economy is based on applying as little fuel as possible (duh), so keep it in whatever gear allows you to barely touch the gas and maintain speed. If you're unsure and have the Navi, use the fuel info menu until you get the hang of it.
