Oil and Fuel
Oil and Gas 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 manu-
al.
• 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 TROY-BILT 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
TROY-BILT 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 addi-
tives directly to the unit's fuel tank.
For proper engine operation and maximum relia-
bility, pay strict attention to the oil and fuel mix-
ing instructions on the 2-cycle oil container.
Using improperly mixed fuel can severely dam-
age 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 Figure 4-1 for specific gas and oil
mixing ratios.
NOTE: One gallon (3.8 liters) of unleaded gasoline
mixed with one 4 oz. (118 ml) bottle of TROY-BILT
2-CYCLE OIL makes a 32:1 fuel/oil ratio.
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.
Remove fuel cap slowly to avoid injury from fuel
spray. Never operate the unit without the fuel cap
securely in place.
Add fuel in a clean, well ventilated area outdoors.
Wipe up any spilled fuel immediately. Avoid creat-
ing 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.
