Oil Specs HarleyDavidson doesnt prescribe a single oil type for all its models across all years The specific requirements vary based on engine size year of manufacture and even riding conditions However they generally recommend oils meeting specific API American Petroleum Institute standards and possessing particular viscosity grades API Certifications Youll often see API certifications like API SG API SH API SJ or even API SN on oil bottles These classifications indicate the oils performance capabilities Higher letters like SN 2 represent newer standards and typically offer better protection against wear and oxidation Always check your HarleyDavidson owners manual for the specific API certification recommended for your model Viscosity Grades The W Factor Viscosity refers to the oils thickness Youll often see viscosity grades expressed as a number followed by a W and then another number for example 20W50 The W stands for winter indicating the oils performance in cold temperatures The lower the number before the W eg 5W 10W the thinner the oil at low temperatures allowing for easier starting in cold weather The number after the W eg 40 50 represents the oils viscosity at higher operating temperatures Higher numbers indicate thicker oil at high temperatures providing better protection under extreme conditions Practical Examples Older HarleyDavidsons
