Im new to this tractor life and I love it. But of course I know nothing, as Sgt Shultz would say. One of the guys at church was saying he is adding ATF to his diesel since his injector pump siezed. Its what his mechanic has always used. So I started asking around. Believe it or not the JD dealer actually said he uses Marvel Mystery oil, others use outboard motor oil, bio diesel. So I will ask the community. Am I being overly concerned. I probably use about 50 gallons a year. Also I was thinking of buying a 55 gallon drum at the beginning of winter. that way I would have it for my generator if needed and if not use it in the tractor next season. I realize moisture is a concern. All inputs appreciated. If it makes a difference i'm in middle TN.
