The service and maintenance section of your owners manual, following the severe duty intervals will get you reliability, along with using quality parts and lubes. The mags are dedicated to performance and looks, unless you can find a fleet owner mag. Simple things will save you money at the pumps. Tire air pressure and the weight of your foot are the two biggest. Tire size is another. If you jump the tire size and your rig has normal gears, gas mileage will suffer. On the other hand on my old '77 Jeep J-20 4X4 that had 5.36:1 gears,going from the stock 9.50 x 16.5 to 31x16.5 tires helped on the highway. Tread design plays a roll, highway tread designs get better mileage than off road or aggressive tread designs. A proper alignment and balanced tires will help. Clean air filters and clean fuel filters. I found a bed cover helps too. Whitelightning
