2005 Ford Explorer, 4.0 SOHC + 4WD. Stock EPA Figure: 15 Combined.


Got this at the end of October 2018. The previous (and original) owner purchased a new Explorer and this was intended to be my winter rig; solid frame, "anti deer" bar and new tires (literally; they had under 1k miles on them at purchase.)

Specs at purchase:

Pennzoil 5w30 Conventional Oil
75w-140 Diff. Oil
Tire PSI: About 30
153k Miles

That didn't seem to work well enough (13 - 14 MPG by the computer?) so I pumped the tires to 40 Cold, filled up the tank and drove about 65 miles before putting Amsoil P.I. (Performance Improver) in the tank and driving at high RPMs on the Interstate with the Overdrive off to clean the valves. This might have worked a considerable amount (tire PSI aside) as I don't suppose Rudy ever used injector cleaner.

After a lot of paint touch up work, fluid film coating and partial tanks (during which the computer said I was getting anywhere from 16 - 19 MPG depending on driving) I filled up the tank and put 2 Oz. of RLI Bio-Plus in the tank before filling. I drove on the interstate for about 30 miles and kept the RPMs around 1500 or less at 55 MPH, netting 20.3 HWY before leaving. Ultimately, this tank was 16.7 MPG (and yes, the MPG computer's accurate) but now for some reason I seem to be getting less mileage on GetGo gasoline; who knows why, though.

Next mods (or ideas for mods: )

1: I could remove the roof rack but family politics are reluctant.
2: An Air Dam is fair play if I have time.
3: Fiberglass in the engine bay to keep it insulated? Sure, why not?
4: No reason why I can't use the ScanGauge II in this while the Suburban's sitting around in the garage.
5: I've been thinking of an Electric Fan conversion with a fan for some other vehicle and I've never done this before. I know I need the fan (or fans,) a fan controller and a temperature sensor that I'll put in contact with the Antifreeze and not just stuck in the fins of the radiator.
6: Switch back to the gas station I was using before I got GetGo fuel at 30 cents per gallon less.
