Ryobi 310BVr - Oil and Fuel Information

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. Ń EVER add fuel additives
directly to the unit's fuel tank.
CAUTION: For proper engine operation and
A m aximum 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.

before filling the fuel tank. Do not smoke
while filling the tank. Keep sparks and open
flames at a distance from the area.
A W ARNING: Remove fuel cap slowly to avoid
injury from fuel spray. Never operate the unit
without the fuel cap securely in place.
A W ARNING: Add fuel ìn 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.
