I've read post where some recommend diesel fuel additives for keeping fuel pumps and injectors clean, displacing water,keeping filters clean and fuel from geling. I've also heard Marvel Mystery Oil recommended for lubricating pumps and cleaning injectors. Also hear Mystery oil prevents other engine wear that a regular diesel additive wouldn't help. My question is would it hurt to use both? Is one better than the other? What do you guys use. I just purchased a new tractor and want to do my part to insure long engine life.
