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 passenger
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 dramatically.
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.
Follow product labeling for use instruc-
tions.
