Engine fuel is a mixture of gasoline and 2-cycle oil. The
correct ratio of gasoline to oil is very important. Follow
the ratios in the Fuel Mixing Table.
Use regular grade unleaded gasoline mixed with
McCulloch 40:1 custom 2-cycle engine oil for best
results. Use mixino ratios in Section 5-3.
CAUTION @
Never use straight gasoline in your unit. Never use a fuel
mixture that has been stored for over 90 days. This will

5-2. MIXING FUEL
Mix fuel in a container equipped with a flexible spout and
strainer. See the Fuel Mixing Table for the correct ratio
of gasoline to oil. Pour half of the gasoline and all of the
oil into the container. Cover the container and shake
vigorously. Add the rest of the gasoline and again shake
container to thoroughly mix fuel and oil.
GAUTTON @
Never attempt to mix the gasoline and lubricating oil in
the fuel tank of the unit.
Special starting fluids SHOULD NOT be used because
seals and other rubber composition parts may be
damaged.

Ihe use of a fuel additive such as STA-BILo Gas Stabilizer
or an equivalent will mrnimize the fornntion of fuel gum
deposits. Such an additive should only be used when the
fuel/oil mix rs prepared. Add 1 1 ml I 0.4 oz. per gallon of
gasoline or mix per instructrons on container. NEVER add
fuel additives directly to the unit fuel tank.

Today's fuels are often a blend of gasoline and one or more oxygenates such as ethanol, methanol, MTBE (ether)
and axonal. These blends are often referred to as gasohol, premium or super unleaded.
We recommend regular unleaded gasoline for use in your McCulloch product. However, if you choose to use a
blended fuel or its use is unavoidable, the following precautions are recommended.
1 .Always use fresh fuel mixed peryou r
User Manual.
Use the special additive ALCOHOL
PROTECiOR'o 1by cold Eagle) or
equivalent to inhibit conosion and
reduce oiltfuel separation (mix as
directed).
Always agitate the fuel mix before
fueling unit.
Defuel tank and run engine dry be-
fore stonng the unit.
PROBLEMS COMMON TO
BLENDED FUELS
Some oroblems associated with use of
blended fuels include:
. Vaoor lock
. Poor warm restart
. Poor performance at high altitudes
