Don't sweat the little stuff. Regular 'ole ATF will work fine. Since it is already so thin, I highly doubt you see little if any increase in fuel mileage. My personal preference is Wally World brand. With the difference in price, if there is a difference in mileage it would take years to pay the difference in fuel savings. One of the biggest advantages of running full synthetic in an auto trans is the fluids ability to withstand higher temps without damaging fluid. Your transfer case doesn't develop the heat of a torque converter.
