Oil Recommendation
Use a high quality detergent oil classified “For Service SF, SG, SH, SJ” or higher.
Do not use special additives.
Determine best grade for use by temperature during
operation, see chart.
SAE 30 40
5F and higher (55C and higher)
is good for all purpose use above 40 °F, use below 40°F
will cause hard starting.
10W-30 0 to 100
5F (−18 to 385C)
is better for varying temperature conditions. This grade of
oil improves cold weather starting, but may increase oil
consumption at 80
°F (27°C) or higher.
Check oil level frequently at higher temperatures.
Synthetic 5W-30 −20 to 120 5F (−30 to 405C)
provides the best protection at all temperatures as well as
improved starting with less oil consumption.
5W-30 40
5F and below (55C and below)
is recommended for winter use, and works best in cold
conditions.
