Keep the engine tuned and keep the air filter clean. Make sure you're using a good synthetic 5W30 oil. Put synthetic oil in the differentials if you haven't already. Make sure the front axle bearings don't have too much preload.
You haven't said if you have a stick or an auto transmission.There are synthetic fluids made for both, but there's not much you can do to an automatic to improve your gas milage. Look for a "power programmer" for your truck. Most of them have an "economy" tune and improve the shifts for an automatic to help milage.
Hope that helps! |
