Using Proper Fuel and Stabilizer
IMPORTANT: Avoid damage! Using stale, contaminated, or
improper fuel can result in engine and fuel system damage.
Repairs caused by stale, contaminated, or improper fuel are
not covered by warranty.
Use regular grade unleaded fuel with an octane rating of 87 octane or
higher. Fuel blends containing up to 10% ethanol or up to 15% MTBE
reformulated fuel are acceptable. Do not use fuel or additives
containing methanol as engine damage can occur.
Always use fresh, clean fuel that is purchased in a quantity that can be
used within approximately 30 days. Fuel stabilizer should always be
added to the fuel each time fuel is purchased. Add stabilizer before
lling the fuel container to insure proper mixing. Such practice helps
prevent engine performance problems and allows fuel storage in the
machine all year without draining.
Store fuel in plastic containers to reduce condensation. Make sure that
the cap on the fuel container is tight to reduce fuel contamination and
evaporation. For best fuel storage life, use a self-sealing gas can.
Fuel is blended to give best seasonal performance. To avoid engine
performance problems such as hard starting or vapor lock, use in-
season fuel. Use fuel during warm weather that was purchased during
that season, and use fuel during cold weather that was purchased
during that season.
Fuel can become stale in machines with engines that are used
seasonally or infrequently during a season. Stale fuel can produce
varnish and plug carburetor or EFI components which can a󰀨ect
engine performance.
Keep fuel storage container tightly covered and in a cool area out of
direct sunlight. Fuel can break down and degrade if not sealed
properly or exposed to sun and heat.
Condensation may collect in the fuel tank because of a variety of
operating or environmental conditions and, over time, may a󰀨ect your
machine’s operation. Fill machine fuel tank at the end of the day.
