Marvel Mystery Oil For Your Old TractorI use Marvel Mystery Oil as a gas additive for my tractor. Marvel Mystery Oil is a penetrating oil that tends to dissolve rust. When added to the gas in a tractor with a steel gas tank, it leaves a thin coating of oil on everything, preventing additional rust, while tending to dissolve the rust that's there. I have also had some trouble with rust in my carburetor, and it helps there, too. I used to always have some red rust in the sediment bowl of my carburetor, but this has gradually vanished since I started using Marvel Mystery Oil in the gas. Admittedly, I could also pay to have my gas tank sealed, or even replace the tank with a new one. But I won't do this until I have to. I doubt that Marvel Mystery Oil is of any particular use as an oil additive, since today's oils are already pretty good, but in old tractors and cars, especially with steel gas tanks with some inside rust, Marvel Mystery Oil good stuff. I also use it as a general light lubricant and penetrating oil, though I'm told that as a rusty-part loosener, Kroil is better. I need to try it some day.
