Oil And Fuel Information - Ryobi 768r Operator's Manual

OIL AND FUEL MIXING INSTRUCTIONS
Old and/or improperly mixed fuel are the main rea-
sons for the unit not running properly. Be sure to
use fresh, clean unleaded fuel. Follow the instruc-
tions carefully for the proper fuel/oil mixture.
Definition of Blended Fuels
Today's fuels are often a blend of gasoline and oxy-
genates 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.
• Use the fuel additive STA-BIL
• Always agitate the fuel mix before fueling the unit.
• Drain the tank and run the engine dry before storing
the unit.
Using Fuel Additives
The use of fuel additives, such as STA-BIL
Stabilizer or an equivalent, will inhibit corrosion and
minimize the formation of gum deposits. Using a fuel
additive can keep fuel from forming harmful deposits in
the carburetor for up to six (6) months. 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.
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.

Gas
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.
UNLEADED GAS
1 US. GALLON + 4.0 FL. OZ.
(3.8 LITERS)
1 LITER + 30 ml
MIXING RATIO - 32:1
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.
WARNING: Remove fuel cap slowly to avoid
injury from fuel spray. Never operate the unit
without the fuel cap securely in place.
WARNING: Add fuel in a clean, well
ventilated area outdoors. Wipe up any spilled
fuel immediately. Avoid creating a source of
ignition for spilt 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.
