Ok so I'm probably making an ignorant post but I've never owned a diesel and do not know a lot about them. Should I run any fuel additives? Anything for anti jelling in the cold? I always thought you had to plug diesels in when it's cold but I guess not anymore? Learning as I go! I want my fuel system to stay as healthy as possible so if an additive can help with wear etc I'm interested in learning more about that.
