Harley-Davidson Genuine H-D® 360 Motorcycle Oil is developed and tested for use in Harley-Davidson motorcycles. Our unique additive package helps prevent engine wear and helps keep your engine cooler, cleaner, and free of sludge, varnish and corrosion. Harley-Davidson air-cooled V-Twin motorcycles operate at higher temperatures than water-cooled engines, thus a specific high temperature additive package is necessary to protect the engine. Be assured, H-D 360 Oil can be trusted in a Harley-Davidson engine. Available in SAE 10W40, 20W50, SAE 50, and SAE 60. H-D Part No. 62600060
