III. Oil and Fuel Specifications
A. Oil
To operate your engine you need to use a clean, high
quality, 2-cycle oil mixed with fuel at a ratio of 50:1. For
recommended mixture ratio of fuel and oil, see Tables 1
and 2. See "A. Mixing Fuel and Oil" instructions. Afterward,
continue reading instructions below.
NOTES
Use of NMMA, TC-WII or TC-W3, JASO FB or FASO FC
classified oil is recommended.
A 32:1 fuel mix ratio is recommended if NMMA oil is not
available. See Table 2 and "A. Mixing Fuel and Oil"
instructions. Afterward, continue reading instructions below.
Special-formulated oils are available at your Authorized

.
B. Fuel
Use unleaded regular, unleaded premium or reformulated
automotive fuel only. You may use gasoline containing the
components identified in Table 3.
• DO NOT use leaded fuel.
• Fuel must be fresh and clean. NEVER use fuel left
over from last season or stored for long periods.
• DO NOT use fuel containing Methanol
(Wood Alcohol).
The use of alternative fuels such as E85
or E20 are NOT recommended for use in
TecumsehPower engines. Alternative fuels with high
alcohol content can cause hard starting, poor engine
performance, and may cause internal engine damage.
NOTE
Damage and/or performance problems that occur from use
of fuels other than those listed in the Operator’s Manuals will
not be considered warranty.
IV. Before Starting Your Engine
A. Mixing Fuel and Oil
