ENGINE OIL
NOTICE! Engine oil is a major factor affecting engine performance and
service life. Non-detergent and 2-stroke engine oils will damage a 4-stroke
engine and are not recommended.
High-quality detergent engine oils are acceptable if the (API) performance rating
is SF, SG, SH, SJ or higher. Always check the API service label on the oil
container for the performance rating.
1. Check the oil level before each use
with a cool engine that is level.
2. Use 4-stroke engine oil that meets
or exceeds the requirements for
API (American Petroleum
Institute) service classification SF.
Always check the API Service label
on the oil container to be sure it
includes the letters SF.
3. Do not use special additives.
4. SAE 15W-40 is recommended for general, all-temperature use. Other
viscosities shown on the chart may be used when the average temperature
in your area is within the indicated range (Fig. 12).
5. Above 27°C (80°F), using 15W-40 oil may increase oil consumption. Check
the oil level more often.
6. Below 4°C (40°F), using SAE 30 oil will cause hard starting.
