Oil Recommendations
Using the proper type and weight of oil in the
crankcase is extremely important. So is
checking oil daily and changing oil regularly.
Failure to use the correct oil, or using dirty oil,
causes premature engine wear and failure.
Oil Type
Use high quality detergent oil of API
(American Petroleum Institute) service class
SG, SH, SJ or higher. Select the viscosity
based on the air temperature at the time of
operation.
A logo or symbol on oil containers identifies
the API service class and SAE viscosity
grade.

IMPORTANT INFORMATION
Using other than service class SG, SH, SJ
or higher oil or extending oil change
intervals longer than recommended can
cause engine damage.
IMPORTANT INFORMATION
Synthetic oils meeting the listed
classifications may be used with oil
changes performed at the recommended
intervals. However to allow piston rings to
properly seat, a new or rebuilt engine
should be operated for at least 50 hours
using standard petroleum based oil before
switching to synthetic oil.
