Synthetic oil
You should use synthetic engine oil that meets the same requirements given for conventional engine oil. When using synthetic oil, you must use oil of the same classification, viscosity and grade shown in this Owner’s Manual. Refer to “Engine oil” F12-4. Also, you must follow the oil and filter changing intervals shown in the Warranty and Maintenance booklet.
NOTE
Synthetic oil of the grade and viscosity noted in chapter 12 is the required engine oil for optimum engine performance. Conventional oil may be used if synthetic oil is unavailable.
