What viscosity is Harley primary oil?
The 20W-50 motorcycle oil’s viscosity is right in the “sweet spot” for optimum operation in all three holes and the volumes of positive reviews we receive back this up. Gear lubes do contain heavy doses of “extreme pressure” additives which many believe prevent transmission wear and provide quieter operation.
What oil should I run in my Harley?
Ans: For all weather conditions, Harley Davidson recommends SAE 20W50 synthetic oils the Twin Cam engine. But if you live in a region where it gets below 40F, you should get something that maintains SAE 10W40 standards. Similarly, SAE 60 H-D is suggested for higher temperatures above 80 degrees.

What causes heat in a Harley Davidson engine?
Heat is caused by the friction between the moving parts as well as by combustion. The radiator is responsible for cooling the top part of the engine. Cooling the rest of the engine, like the pistons, rod bearings, timing gears, crankshaft, camshaft etc., is up to engine oil. As oil passes over these heated surfaces, it absorbs the heat.
