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 motor 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 10W-30 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. 4).
5. Above 27°C (80°F), using 10W-30
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.
HOW TO CHECK OIL
1. Level the engine or the equipment the engine is mounted on.
2. Clean the oil fill area of any dirt and debris to prevent contamination that can
damage the engine.
3. The engines has a dipstick that is either part of the oil fill plug (K) or a separate
component (see Parts Identification).
a. Remove the dipstick (K) and wipe with a clean cloth.
b. Reinsert the dipstick into the filler neck until it rests on the opening’s rim.
Do not screw the oil fill plug back into the opening.
