Engine oil is a major factor in the performance and service life of the engine. Always use the proper grade of oil for the lowest temperature expected before the next scheduled oil change. Your authorized dealer has the proper oil to suit your requirements. Refer to Table 1.
This motorcycle was originally equipped with Genuine H-D 360 Multi-Grade 20W50 engine oil, and is the preferred oil under normal operating conditions. If operation under extreme cold or heat are expected, refer to Table 1 for alternative choices.
If it is necessary to add oil and Harley-Davidson oil is not available, use an oil certified for diesel engines. Acceptable diesel engine oil designations include: SH, CH-4, CI-4 and CJ-4.
The preferred viscosities for the diesel engine oils in descending order are: 20W50, 15W40 and 10W40.
At the first opportunity, see an authorized dealer to change back to 100 percent Harley-Davidson oil.
