New member here, sorry if this has been asked before, but I couldn't find it.
I have a 2004 Sport Trac XLT with the 4.0L-6, automatic.4x4, bone stock, no mods.
When I got it in 2006, used from the service manager of the dealer, with 15k miles on it, I checked it the first weekend and it got 21 on the highway. It got 20 or so and averaged 17/18 most of the time for a couple years, all around driving. I didn't buy it for the MPG, but...
Over the years, even with care (and I am anal about that) the MPG has dropped. And dropped. Now it sees about 14/15 highway, and you don't want to know what it does with E85 or with it in 4x4 in winter! Still, summer, highway, and 15? I've also tried different brands of gas. No help.
The shop and I are at wits end on this issue. New plugs, you name it, no codes, even a new fuel line, no leaks...
Anyone have any ideas?
