Engine oil is a major factor affecting engine performance and service

life. Non detergent and 2-stroke engine oils will damage the engine

and are not recommended.

SAE 10W-30 is recommended for general, all-temperature use. Other
viscosities shown in the chart may be used when the average
temperature in your areais within the indicated range.
Remove the oil filler cap and wipe the dipstick clean.
Check the oil level by inserting the dipstick into the filler neck
without screwing it in.
If the level is low, fill to the top of the oil filler neck with the
recommended oil.
Use 4-stroke motor oil that
meets or exceeds the require-
ments for API service classifi-
cation SJ. Always check the API
SERVICE label on the oil contain-
er to be sure it includes the letter
SJ.
