I have an 02 v8 Eddie Bauer. When I bought the truck (used of course) I was seeing about 15 mpg around town and 18 mpg on the highway, combined roughly 16-17 mpg. Truck had ~ 140k on it. I was tickled with that. I'm pretty thorough about maintenance, so I wanted to make sure the truck was tuned up properly. First thing I did was replace the factory original looking fuel filter. Gas mileage went to crap, about 11 city and 13 highway. That is a big difference annually. So I replaced the plugs with some platinum ones. No change. I replaced the front two O2 sensors, BARELY an increase, maybe 1/2 mpg. I'm lost. Why would a new fuel filter KILL my gas mileage by 20% or more? Even better, what's a solution to get it back where it was? My air filter is new also BTW.
Thanks
