Well I am waiting to get my truck back hopefully by thursday as it is getting painted now after it decided to run through my barn door. The one godd thing to come out of this is a new better SS bug deflector and I finally got fog lights. LOL The joys of life. It is killing me I have been without it for a week now and it seems like a month. Anyways, with Amsoil how often are you guys/gals (gotta be pc here) changing the oil and filter or just filter. With my old gasser I changed filter every 4000 and oil at 25000 worked great. How often should I change the fuel filter? thanks for all your help.
