Maybe someone can help me out here since I'm at my wit's end. Even the local Toyota dealer service department didn't know what to say.
I've noticed that my gas mileage is dropping with each tank over the past few month. Currently, I don't have a Scangauge to accurately measure but this is what I've got...
Today, at 3/4 tank, I noticed that I'd clocked 32 miles on my trip odometer which was reset when I filled up the tank. (This is all granny-style city driving.) With a 20 gallon tank divided into 4 quarters (5 gallons per quarter-tank), that means I'm getting 6-7 miles per gallon?!?!
The mods that I've done to the truck (2010 4x4 Access Cab V6):
~285/85/16 tires w/ 3" Icon Stage 2 lift kit
~armor: ARB front bumper, AllPro rear bumper, Demello sliders, BudBuilt skid plates
~AFE air intake w/ Magnaflow catback exhaust
~Optima dual-battery setup
Does anyone have any idea of what's going on? Any ideas of what might be causing my mileage issues? Any suggestions?
