PUTOLINE Oil Fuel Stabilizer prevents petrol oxidation. When storing your motorcycle or quad for long periods (more than 1 month) there is a risk that the remaining fuel in the tank can oxidize. This will cause gum and varnish build-up in the petrol tank as well as in crucial parts in the carburettor. As a direct result, this can cause starting problems and also prevent the engine from idling efficiently. Putoline Fuel Stabilizer will prevent these kinds of problems occurring.
