Ford V10 gradual reduction in fuel economy
I have a 26' Class C on a 2000 Ford E450 chassis with V10 engine now with 115,000 mile on it. I used to average 8.5 mpg pulling a 3400 lb toad but over time the economy has deteriated to the 7.5 to 8....

Hi whemme,
Check for this.......It is possible someone who worked on your rig made this easy mistake, causing poor fuel economy and poor performance. It is easy to check for.
Pop-off the oval air intake from above the radiator and pivot it upward. Look into the hole where it was snapped into. If you see a black plastic flap that interferes with the flow of air, you need to remove the black plastic shroud above the radiator and fold the flap back while resetting it into position.
There was a recall in 2010 on that flap. Apparently a new-bee line worker was not holding the flap back when installing the black plastic top radiator shroud. It is conceivable that an unsuspecting mechanic could make the same mistake. I almost made that mistake myself on our 2007 E350 when reinstalling the top shroud after removing a bird that died hitting and getting lodged into our front grille area.
