Oil And Fuel Information - Craftsman 316.350850 Operator's Manual

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 (less
than 60 days old) 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 and lead to for-
mation of acids during storage. When using alcohol-
blended fuel, use fresh fuel.
Using Blended Fuels
If you choose to use a blended fuel, or its use is unavoid-
able, follow recommended precautions:
• Always use the fresh fuel mix explained in your opera-
tor's manual
• Always shake 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 your unit contains
a fuel additive which will help inhibit corrosion and mini-
mize the formation of gum deposits. It is recommended
that you use our 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.
CAUTION:
mum 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.

To Obtain Correct Fuel Mix:
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.
