Hey guys. I'm a newbie on here as well as with diesel engines, so bear with me. I just bought a 2001 F350 Powerstroke with 114,500 miles on it. It was owned by one person, an older gentleman who really only used it to pull his travel trailer. As far as I know, it is bone stock. I won't be hauling much more than a horse or two, which I suppose it will do with total ease remaining stock (for now). I would appreciate any suggestions on up-keep such as oil, fuel filter changes, additives, at what temp to plug it in, etc., etc., to keep this thing purring like it does. It's not gonna be my everyday vehicle, also. Sorry guys, and I appreciate your help!
