I've got a 2006 3.7 Dakota 2WD club cab with 85,000 miles on it. Up until about a year ago, I'd get ~20mpg highway and ~17mpg city. Over the past year, I've noticed the mileage slowly decreasing. Over Christmas, I drove it ~400 miles round trip to my folks house, and got 17.5mpg with no headwind. Lately it's been around 14.5 city and 17.5 highway.
Any ideas why??? Plugs were replace a year ago at 70k miles. I'm also really anal about keeping the tires properly inflated. It seems to idle nice and clean, with no stumble. At this point, I've just sorta chocked it up to the truck getting older. Is there something I may be missing?
Thanks for your help.
