The PUTOLINE oil fuel stabiliser prevents the oxidation of petrol. When storing the motorcycle for long periods (more than 1 month) there is a risk that the fuel remaining in the tank may oxidize. This will cause rubber and paint to build up in the fuel tank and crucial parts of the carburetor. As a direct result this can cause starting problems and also prevent the engine from idling efficiently. The Putoline fuel stabiliser prevents this type of problem.
