Ring Free Fuel Additive
Gasoline is a precise blend of many differ-
ent substances, each chosen to give certain
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 passenger cars,
but they can have detrimental effects in
marine engines, particularly 2 cycle out-
boards because of increased deposits in
the combustion chamber. When enough
deposits collect, piston rings begin sticking.
Performance drops and engine wear
increases dramatically.
While many additives available may reduce
deposits, Yamaha recommends the use of
Ring Free Fuel Additive, available from
your Yamaha dealer. Ring Free has repeat-
edly proven its ability to clean combustion
deposits from inside the engine, notably the
critical piston-ring-land area, and fuel sys-
tem components. Follow product labeling
