8.5 Mpg???
I've been looking at Expiditions off and on for a couple years and finally just picked up an '01 EB less than a week ago. Is the mileage computer in these things really accurate? I've only driven it about 60 miles around town and it's reporting 8.5 MPG. I was expecting around 12.
I have not checked this yet by topping off and calculating on my own. I was just wondering if the milage computer was really all that accurate.
If this is right, any ideas why it's so low? I've done the basics, changed oil, new filters. Everything on it is stock at the moment.

My 2001 4x4 5.4 L gets about 13mpg around 65% city 35% highway summer driving. The computer has been within 1/2 mpg either way over 10 of my manual calculations. I believe it is reasonably accurate.

Mine is pretty close when used through out 3/4 of a tank. Not to accurate right after being reset unless I am steady state driving. I have a 4x4 5.4 and get around 12.5 city on 285/75/16 tires and arounf 16 highway and 11 witha 3500 pound boat. Do the math when you fill up and see if it is really 8.5 if it is look into O2 sensors, possible bad Cat Converter ot EGR system problems. Good luck let us know what turns up?

The computer on my 01 EB 4x4 is pretty accurate as far as MPG goes, usually within 0.5 MPG of manual calculations. What I have found not accurate is miles left on tank. The read out gets down to show 10-20 miles left, and I usually have 50-6- left on the tank. Currently, 14.8-15.2 MPG local city, and 16.5-17.0 highway.

It's looking better now. It's been coming up the more I drive. I re-set it again last week and it's showing about 12 mpg average which sounds a little more normal.
I had forgotten that I sat with the truck idleing for an hour or more with the A/C on high the day I got it thumbing through the manual, setting memories, key fobs, etc. It came up steadily the more I drove it.
thanks
