So nearly 2-1/2 years later, about a month ago I finally got around to changing the drivetrain fluids to synthetic in the Jeep... only difference from my list in post #1 is that I used Castrol ATF+4.
It may be wishful thinking, but it seems like our mpg is up... maybe 1 mpg? To be honest, I don't religeously check the mileage because it's too depressing, but the dash readout has been consistently higher than I remember...
Does anybody have some real numbers. Unfortunately (actually fortunately), my wife also changed her driving route a bit recently due to a new job, so that could be the factor as well.
