other thing is to make sure your rear diff fluid is changed and is topped off.

driving from my home to johnson valley is around 460 miles.

going there, i didnt know at the time, but i was low on the rear diff lube. got around 15'ish.

going home, i topped off because i found out i had this issue...

but you know what? i avg 18-20 mpg going home...
