Ring Free Fuel Additive Gasoline is a precise blend of many differ- ent substances, each chosen to give cer- tain characteristics. Gasoline blends have been changing in recent years in response to concerns about pollution and resulting emissions regulations. One of the most obvious changes has been the elimination of lead from most fuels. As gasoline has changed, the amount of additives such as aromatics and oxy- genates has increased.
These additives are important for the engines in passen- ger cars, but they can have detrimental effects in marine engines, because of increased deposits in the combustion chamber. When enough deposits collect, piston rings begin sticking. Performance drops and engine wear increases dramati- cally. While many additives available may reduce deposits, Yamaha recommends the use of Ring Free Fuel Additive , avail- able from your Yamaha dealer. Ring Free has repeatedly proven its ability to clean combustion deposits from inside the engine, notably the critical piston-ring- land area, and fuel system components.
