Engine Oil Level Check

Check the engine oil level with the engine stopped and with the engine in a level position.

1.  Remove either side mounted filler cap dipstick or high oil fill dipstick and wipe it clean. 

2.  Insert the dipstick into the filler neck and turn clockwise until fully seated. Then remove the dipstick by turning it counter clockwise. 

Check the oil level shown on the dipstick.

3.  If the oil level is low, fill to the edge of the oil filler hole with the recommended oil.

4.  Securely screw in the filler cap/dipstick. Running the engine with a low oil level can cause engine damage.  

Always check the engine oil before start up.

Recommendations

Engine oil affects performance and service life. Use 4-stroke automotive 

detergent oil.

SAE 10W-30 is recommended for general use. Other viscosities shown in 

the chart may be used when the average temperature in your area warrants.

The SAE oil viscosity and service classification are in the API label on the oil 

container. The manufacturer recommends you use API SERVICE category 

SJ engine oil, or better.

Drain the used oil while the engine is warm. Warm oil drains quickly and 

completely. Avoid contact with hot oil.

1.  Place a suitable container below the engine to catch the used oil then remove 

the filler cap/dipstick and the drain plug. 

2.  Allow the used oil to drain completely, then reinstall the drain plug, and 

tighten it securely. Do not over tighten. Dispose of used motor oil in a 

manner that is compatible with the environment. We suggest you take used 

oil in a sealed container to your local recycling center or service station for 

reclamation. Do not throw used oil in the trash, pour it on the ground, or pour 

down a drain.

3.  With the engine in a level position, fill to the outer edge of the oil filler hole 

with the recommended oil. (see fill limits right)

• NOTICE  

Running the engine with a low oil level can cause engine damage.

4.  Securely screw in the filler cap/dipstick.
