The container has recommendations for how much to add to the fuel tank ( believe it's on the order of 2 oz to 10 gallons Gasoline ).

Folks with Model L Gravely tractors swear by to prevent the exhaust valve from sticking open...

Never heard of it doing any harm.

I use it in my old iron; have never sprung for the "Marvel Inverse Oiler" ( or Ampco Cylidner Lubricator )... just add to fuel.
