I saw a study where one of the best additives, for lubrication only, was vegetable oil. Was that study partially funded by the bio diesel lobby? I don't know. I did get some and try it out of curiosity(wondering about plugged filters and such) without any trouble. Did it do any good? I haven't a clue. Sometimes an engine will tell you what it needs, like onefarmer below. The one that has bothered me is my Cummins L10 truck engine with mechanically operated injectors. They were all replaced at one time. Fuel is supposedly treated for or by the place where I get it(they use it in their own fleet) Every little while an injector will stick. For a while, I treated the fuel also. Then another injector stuck, so I quit with the additive.(I tried more than one) This summer, after an injector stuck on a foggy morning in unfamiliar territory, and a tow bill, I started adding some veg. oil with every fill up. I will keep it up until something else happens! I just got a new to me, small, low houred tractor. After idling to warm it a little, I speeded it up to find it smoking, skipping, popping, and just running terrible in general. After getting over my initial fear, I got some Power Service additive, filled it on up with my fresh fuel, and ran it at PTO RPM on the mower I intend to use it with, and it has cleaned right up and straightened out.
