AMEN... The book says change oil every 7500 miles, I do mine 3-4000 and the fuel filter gets changed every other OC when I wash the K&N air filter. Oils is cheap, engines are expensive. I run the NAPA Golds, have a friend that is a Manager. Include 2 Qts of Lucas oil additive with each change and a pint of Marval Mystery Oil in the fuel tank.gsbrockman said:A more frequent fuel filter change is cheap insurance in regards to the fuel system & injectors these trucks use.
