what can you put in a gas tank to keep it from rusting when in storage?

Don Hooks · Sep 10, 2013

Anything that will exclude oxygen: diesel, motor oil, gasoline (without ethanol), or even carbon dioxide or nitrogen, although the last two are pretty hard to seal up. If you are going to store it just for a season, fill it with non-ethanol gasoline with seafoam or stabil; for perhaps a year, diesel, kerosene, or motor oil remembering to plug the line to the carburetor so you don"t accidentally gum it up. Speaking of the carb, for long-term storage you might want to take it off and put it in a plastic bag and seal the manifold (and the exhaust pipe) to keep pests out.

Boy use guys up north with your cold weather to deal with, glad it don't come into play down here,all I can contribute is a "warm ear."

Whilst it is illegal in most countries and I would never advocate breaking the law......... :lol: You could put a few lead fishing sinkers in the tank.

Minute quantities of lead are released into the fuel and the inside of the tank gets a microscopic layer of lead to inhibit rust.

One poster suggests using carbon dioxide or nitrogen. Great idea if you can seal the tank and pressures when heated (sunlight, summer weather changes) don't create a problem.

BUT---carbon dioxide is NOT inert. Any moisture will create carbonic acid and eat your steel tank.

Just be careful and save that tank.

For long-term storage I'd be inclined to shut fuel valve off tight and ensure no leaks and fill tank with highly stabilized diesel and try to seal cap from breathing.

Please post back how you proceed and results so we may all learn.
