I have a 2001 Dak 4x4, 4.7L. It used to get better mileage than it does now - I daresay it's topping off at 12 or 14 highway (possibly less, I haven't done an actual measurement), when it was getting 19/20 highway when new.
I'm not a mechanic, and being in England, do not have access to a Dodge dealer (closest is the Jeep/Chrysler dealer). I do, however, have access to a hobby shop on base, that'll do a variety of minor repairs/services. I don't mind doing my own work, with proper instructions.
There's nothing wrong with the truck that I can tell. It gets the ol' "evaporative emission leak" error code, despite the new gas cap, but I'm told that'll not affect the truck's performance.
The poor fuel economy didn't worry me as much before, but now that the rules on base have changed, and I'll be paying $6.50 per gallon for gas on vacation, it's become more of a concern.
Anything I can do to help improve the gas mileage? Anything I should be looking at (perhaps some preventative/standard maintenance I may have overlooked) that would explain the dropping mpg?
Thanks for your help!
