Harley Davidson Oil

 
One of the main benefits of using a synthetic motorcycle oil is actually it is resistance to oxidation as well as thermal deterioration, which often slow down the development of sludge and build up that play a role in greater wear. Previously, Harley-Davidson® has protected usage of their Genuine H-D Oil simply by disagreeing that oil break down in extreme heat is a non-issue due to the fact extreme heat conditions are not necessarily typically encountered by motorcycle motors, while the exceptional cold-temperature advantages of synthetics also do not pertain to Harleys.

The truth is, motor oil in Harley-Davidson® motorcycles is susceptible to quite high temps. Being air-cooled, Harley-Davidson® engines get particularly hot while idling in traffic, frequently attaining temperature ranges as much as 240 plus degrees Fahrenheit. While heat and oxidation increase, the same is true viscosity, detrimentally impacting the lubricating qualities with the oil plus escalating wear.
 

Delivers Superior Rust Protection
Motorcycles are prone to rust from storage, humidity and short drives. Rust can cause major damage such as roller bearing failure, uncontrolled wear, compression loss and blow-by. Good rust protection, however, comes by design and is not natural to engine oils. Unlike many motorcycle oils, AMSOIL MCV contains special anti-rust agents. It passes the ASTM D-1748 humidity cabinet rust test and clearly demonstrates superior rust protection (see photos below).

Provides Extreme Pressure Quality Protection for Gears
With AMSOIL MCV, it is not necessary for different transmission or even key chaincase lubes. It truly is definitely shear stable and won’t thin from mechanized action. AMSOIL MCV works just like a gear lube minus the unwanted effects of excessive pressure ingredients. Inside the FZG gear test, AMSOIL MCV accomplished the best score which has a “zero” wear rating (see photos below).
