Engine Oil Recommendation
Use only high detergent, premium quality motor oil certified to meet or exceed US automobile manufacturer's requirements for Service Classification SE (previously Service Classification MS).
Motor oils intended for Service SE or MS will show this designation on the container.
The regular use of special oil additives is unnecessary and will only increase operating expenses.
Engine oil should be changed at the intervals prescribed in the Maintenance Schedule.
NOTE: Engine oil is a major factor affecting the performance and service life of the engine. Non detergent and low quality oils are specifically not recommended.
Viscosity
Viscosity selection should be based on the average atmospheric temperature in your riding area. Change to the proper viscosity oil whenever the average atmospheric temperature changes substantially.
| Recommended oil viscosity: | |
| General, all temperatures: | SAE 10W-40 |
| Extreme, high temperatures: | SAE 20W-50 |
| Alternate: | |
| Above 59°F | SAE 30 or 30W |
| 32" to 59°F | SAE 20 or 20W |
| Below 32°F | SAE 10W |
| 32" to 59°F | SAE 20 or 20W |
| Below 32°F | SAE 10W |
