A Fuel blend differs from season to season for the best
seasonal engine performance. To prevent engine
performance troubles such as vapor lock or hard
starting, use fuel within the season in which the fuel is
purchased.
A
Infrequent use of the engine during a season can
make fuel stale in the fuel tank of the machine. Stale
fuel condition can cause engine performance troubles
by varnish and plugged carburetor components.
A
Seal the fuel storage container tightly and store it out
of sunlight and heat to prevent fuel degradation.
A
Condensation in the fuel tank may occur because of
various operating or environmental conditions. To
reduce condensation and avoid affecting machine
operation, fill the fuel tank at the end of daily
operations.

Do not use old fuel.
[Use of alcohol mixed gasoline (Gasohol)]
Use "gasohol" only when the ethanol additive is less than
10% of the fuel. The use of methanol additive is not
recommended. For the best results, use unleaded fuel
with a minimum of 87 octane.
