Quick question for you D owners out there.

When I fill the wifes car up with fuel the miles to Empty always says less than 650. Now I remember when we first got the car I thought it would constantly be above 700. Reason I noticed this is I would fill up the car and drive about 30-50 miles and the fuel needle would drop from full to 3/4. Even if I would allow the foam to go away and pack it FULL. Every once in a while it will say full and drive 100 miles before the needle moves. Just curious if anybody else has experienced this. Not a big deal but trying to figure out if I have something going on.

It is basing the 'Miles to empty' calculation based on the current mpg average.

Example: In this case my around town driven Trax.
My current average is 31.1 mpg......I filled last Saturday prior to a one hour highway drive to my hangar. My 'Miles to Empty' showed 387 miles (I remember this kind of crap).
When I arrived at the hangar, the 'Miles to Empty' now showed 435......after driving 58 miles.
It had been rising for the entire ride based on my much lower fuel usage at highway speeds.

Anyways, I don't think you are seeing anything abnormal.

In the last few weeks I have been looking at mine creeping into the 400's. It is all a function of how and where you drive. If you spend a lot of time on the hwy it will be higher. It is all a calculation of your driving habits. Even in the city I have been looking at my instant MPG in the high 30s (esp since I have started "hypermiling")

Thanks for the reply. Makes sense

When I fill mine to the rim, I can often drive 200 miles or so before the miles to empty starts going down. Also, more relevant to your question - I have seen some wild variations in my miles to empty after refueling at different times.

I thought they put some buffer room on those things too. IE 0 miles to empty doesn't mean you are totally empty. Don't hold me to that though. I certainly have not tried.

When I top off my tank to the brim I can drive 175 miles before the fuel gauge moves off the F mark on the fuel gauge

I've been able to go over 100 miles past when it says LOW for miles to empty.
