AMSOIL Synthetic Motorcycle Oil Demonstrates Outstanding Protection in Extreme Heat

AMSOIL Synthetic 20W-50 Motorcycle Oil Bottle

Protection against extreme heat is of the utmost importance in motorcycle applications. The aircooled V-twin engines used in Harley-Davidson motorcycles can get extremely hot, particularly when idling or traveling at low speeds.

If a motorcycle oil cannot withstand hot operating temperatures, its ability to provide adequate engine protection is compromised. AMSOIL Synthetic Motorcycle Oil is formulated to withstand extreme heat conditions beyond the hottest temperatures motorcycles typically experience, providing peace of mind that motorcycles receive outstanding protection and performance no matter how extreme the operating conditions.

Dynamometer Testing

To demonstrate its extreme-heat protection qualities, AMSOIL 20W-50 Synthetic Motorcycle Oil (MCV) was subjected to a dynamometer test designed to simulate conditions even more extreme than the demanding stop-andgo driving conditions of a motorcycle rally or parade route.

A 2012 Harley-Davidson FXDB Dyna Street Bob motorcycle equipped with AMSOIL 20W-50 Synthetic Motorcycle Oil was operated for 68.5 minutes at low speeds, with significant idle time broken by engine revving. Like most Harley- Davidson motorcycles, the Dyna Street Bob features an air-cooled V-twin engine, which relies on cooling fins arrayed along the cylinder walls to conduct heat away. To create the most-severe operating conditions possible, the electronic temperature controls, which safeguard the motorcycle when temperatures reach dangerous levels, were deactivated. The test subjected the oil and engine components to intense heat not normally experienced in the real world, with cylinder temperatures reaching more than 500°F.

The extreme temperatures were no match for AMSOIL Synthetic Motorcycle Oil. After nearly 70 minutes of torturous testing and heat exposure, oil analysis revealed no change in oil viscosity and only minor levels of oxidation, TBN depletion and wear.

Not only did AMSOIL Synthetic Motorcycle Oil prevent the engine from overheating and seizing, it did so without losing chemical integrity or ability to protect vulnerable engine components, demonstrating that it provides outstanding protection even in compromising and severe high-temperature riding and idling conditions not experienced by most riders.

As temperatures climbed to more than 500°F in the cylinders, an infrared camera revealed the redhot conditions that assaulted the engine components and oil.


As heat breaks oil down, the viscosity typically rises until it is significantly out of grade and must be changed. AMSOIL 20W-50 Synthetic Motorcycle Oil showed no change in viscosity following the extreme-temperature test, demonstrating its outstanding resistance to thermal breakdown and its ability to provide excellent protection in the most severe conditions.
