Mixing Ratio; Oil And Fuel Information - Cub Cadet ST2020 Manual Del Operador

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 30 days old).
Using Blended Fuels
If you choose to use a blended fuel, or its use is unavoidable, follow
recommended precautions:
• Always use the fresh fuel mix explained in 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 Fuel Additives
The bottle of 2-cycle oil that came with this unit contains a fuel additive that
will help inhibit corrosion and minimize the formation of gum deposits. Using
the 2-cycle oil included with this unit is recommended. 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.
Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded gasoline in
a separate fuel can. Use a 40:1 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 3.2 oz.
(95 ml) bottle of 2-cycle oil makes a 40:1 fuel/oil ratio.
NOTE: Dispose of the old fuel/oil mix in accordance with federal, state
and local regulations.
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.

*WARNING:
DO NOT USE E85 FUEL IN THIS UNIT. It
has been proven that fuel containing greater than 10% ethanol
will likely damage this engine and void the warranty.
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 outdoor area.
Wipe up any spilled fuel immediately. Avoid creating a source
of ignition for spilt fuel. Do not start the engine until fuel vapors
dissipate.
