Preventing fuel tank corrosion

[superjocko]

Having seen a few threads about leaky/rusty gas tanks I just figured that I'd throw this out there for anyone that maybe hadn't heard it before. Putting just a splash of two-stroke oil in your fuel can help to prevent corrosion. I'm not talking about mixing it 40:1 or any particular ratio for that matter. About a quart jug capful of oil to a full tank of fuel is plenty. If you were to bother to figure out the ratio it'd be probably be more than 1000:1. If you do want to bother to figure a ratio, I wouldn't go any more than 500:1 for gas you're going to use in a four-stroke engine. Just enough that it leaves the tiniest bit of an oily film anywhere it comes in contact. It won't hurt a thing at that small concentration and will lube the internal carburetor parts and even ever so slightly improve valve stem lubrication and piston ring sealing. Any old cheap Walmart universal two- stoke oil will do, or any other brand you happen to have around for two-stroke bikes, or your weed-eater, leaf-blower, etc. Like I mentioned, just don't go overboard and pour already mixed two-stroke gas, or some big quantity of oil, in your tank. Just a splash of oil in plain gas is all you want.
