I am a believer in using top tier gasoline. I consistently see 1-2 mpg better with shell gas.. Plus it's supposed to be better for the car.
Other than that set tire pressure a little higher and drive slower.
Another suggestion I got was: use a lighter grades of motor oil, transmission fluid, and rear differential fluid; to offset the lowered protection of dino-based oil, go with a superior wearing synthetic, e.g. Amsoil 0W30 in the engine, and even in the manual transmission (yes, my transmission mechanic swears by putting 30 weight oil in the manual tranny). If you have a automatic, you can try a leaner version of ATF. But you can still use a lighter transaxle fluid. (Recall: in the automatic drive All-Tracs, the transmission and the transfer case are separate because they use different fluids: ATF and transaxle oil respectively. But in the manual drive All-Tracs, the transmission case and the transfer case are connected so they use the same fluid. But the rear diff still needs a hypoid gear oil, but instead of dino 90 weight, go with synthetic 75W-80. I have yet to try this. |
