I have been using this type of Castrol Valve Master for some time now in my classic motorcycles as it prevents ethanol damage to fuel components such as carbs, fuel lines and even fuel tanks. It is also seems to extend the shelf life of petrol in store over a winter period for things like garden machinery.
