OIL AND FUEL INFORMATION
OIL AND FUEL MIXING INSTRUCTIONS
Old and/or improperly mixed fuel are the main reasons
for the unit not running properly. Be sure to use fresh,
clean unleaded fuel. Follow the instructions carefully for
the proper fuel/oil mixture.
Definition of Blended Fuels
Today's fuels are often a blend of gasoline and
oxygenates such as ethanol, methanol, or MTBE (ether).
Alcohol-blended fuel absorbs water. As little as 1 % water
in the fuel can make fuel and oil separate. It forms acids
when stored. When using alcohol-blended fuel, use fresh
fuel (less than 60 days old).
Using Blended Fuels
If you choose to use a blended fuel, or its use is
unavoidable, follow recommended precautions.
• Always use fresh fuel mix per your operator's manual.
• Always agitate the fuel mix before fueling the unit.
• Drain the tank and run the engine dry before storing
the unit.
Using Fuei Additives
The bottle of Ryobi 2-Cycle Oil that came with your unit
contains a fuel additive which will help inhibit corrosion
and minimize the formation of gum deposits. It is
recommended that you use only Ryobi 2-Cycle Oil with
this unit.
If unavailable, use a good 2-cycle oil designed for
air-cooled engines along with a fuel additive, such as
STA-BIL® Gas Stabilizer or an equivalent. Add 0.8 oz.
(23 ml.) of fuel additive per gallon of fuel according to the
instructions on the container. NEVER add fuel additives
directly to the unit's fuel tank.
A
CAUTION: For proper engine operation and
maximum reliability, pay strict attention to
the oil and fuel mixing instructions on the 2-
cycle oil container. Using improperly mixed
fuel can severely damage the engine.
Thoroughly mix the proper ratio of 2-cycle engine oil with
unleaded gasoline in a separate fuel can. Use a 32:1
fuel/oil ratio. Do not mix them directly in the engine fuel
tank. See the table below for specific gas and oil mixing
ratios.
NOTE: One gallon (3.8 liters) of unleaded gasoline mixed
with one 4 oz. (120 ml.) bottle of Ryobi
2-Cycle Oil makes a 32:1 fuel/oil ratio.

A
WARNING: Gasoline is extremely
flammable. Ignited vapors may explode.
Always stop the engine and allow it to cool
before filling the fuel tank. Do not smoke
while filling the tank. Keep sparks and open
flames at a distance from the area.
A
WARNING: Remove fuel cap slowly to avoid
injury from fuel spray. Never operate the unit
without the fuel cap securely in place.
A
WARNING: Add fuel in a clean, well-
ventilated area outdoors. Wipe up any spilled
fuel immediately. Avoid creating a source of
ignition for spilled fuel. Do not start the
engine until fuel vapors dissipate.
NOTE: Dispose of the old fuel/oil mix in accordance to
Federal, state, and local regulations.
