The correct engine oil viscosity grade is dependent upon ambient temperature. See the table below for the recom-
mended viscosity at different ambient air temperature ranges.
-40 °C -30 °C
-40 °F -22 °F
In environments with extreme air temperatures that require long periods of use of the machine, use SAE 50 oil for
extremely high temperatures and SAE 5W30 for extremely low temperatures.
SAE 5W-30
SAE 10W-30
