Well, to tell you the truth I wrote off the mpg due to having the tires inflated to 20 psi. I had heard the change from auto to manual locking hubs helps for 2 mpg and I had problems with one sticking and not slipping.
I kind of knew one of the brakes was sticking up front, but I usually engine brake. The engine Ive always used regular oil, but the synthetic mix had a toy car and was 15 bucks for 5 qts, so I couldnt resist. I also no longer have a few drops of oil where I park like before.
My mod for a softer ride was to go to 8 inch wide rims from the stock 6 ones. I found arca racing rims are about the same weight, but made of steel. About 25 lbs is the weight of the alloys. Regular dot approved steelies are like 50 lbs a piece.
I am running p235/75r15 yoko touring S tires vs the typical off road mud or swamper tires.
