05 EXPY miles to empty.
This has me stumped. When I get down to 50 miles to empty I go and fill up. The gas pump stops around 22 gals. I have a 28gal tank. So with 6gals still in the tank and 50 miles to empty does this mean that I will only get about 8 miles to the gallon on what is left in the tank. In my 03 Expy when I got to 50 miles to empty I had about 3 gals of gas left. Has anyone else run into this problem.

Thats exactly my experience/observation as well. Though, the fuel guage is not all the way down at that point, and gives a little better picture of the actual fuel situation ...
One explaination could be that it calculates the 50 mile warning based on the worst possible fuel economy i.e. 8 mpg. So you've got 50 miles more to go even if you somehow start getting a really bad MPGs. So that the warning will almost never be wrong. Had Ford decided to generate the warning based on the *current* MPG reading then any subsequent fall/decline in MPGs would not be accounted for and one could run out of fuel in less then 50 miles - which would then open doors for litigation and Ford bashing ...

The number it gives is only an estimate and I wouldn't bank on it.
My 97, 99, 2000, 2004 were all inaccurate at some point.
I feel it errs on the consevative side most of the time.
I consider it normal.

Distance to empty is calculated using a running average fuel economy, which is based on your recent driving history of 800 km (500 miles). This value is not the same as the average fuel economy display. The running average fuel economy is reinitialized to a factory default value if the battery is disconnected.
