I use Marvel Mystery Oil 6oz for every 10 gallon of fuel, also filled fuel filter with it and started truck waited 15 sec and shut her off. I waited a day started her up and she runs great now. when my glow plugs do not light you can smell the Marvel Mystery Oil in the air lol. when I got my truck no one was able to get her started so she sat for two years. She blew White Smoke and quite running all the time. The Cure run ATF or Marvel Mystery oil through fuel filter like everyone said. I just use Marvel because $3.88 a quart and it burns like diesel. Welcome to the Forum and Good Luck on the truck.
