3.4 Fuel System

3.4.1

Fuel Specifications

Use a clean, good-quality unleaded fuel with an octane
number of 87. Use fresh gasoline to ensure it is blended
for the season and to reduce the possibility of the
formation of gum deposits that could clog the fuel
system. Do not use gasoline left over from the previous
season.
Kohler Co. recommends unleaded fuel because it
leaves fewer combustion chamber deposits. Never mix
oil with fuel.
Note: Consult
the
engine
