Spring has sprung here in the United States and that means it is time for maintenance of our cars, trucks and powersports equipment. While there is still a chill in the air it is a great time to get out and ride a motorcycle. Soon summer will be here and heat from that V-Twin will make you sweat while at the stop lights. The air-cooled V-twin engines used in Harley-Davidson motorcycles can get extremely hot, particularly when idling or travelling at low speeds. 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.
V-Twins Get Hot
Harley-Davidsons* and other bikes with big V-twin engines generate significant heat, especially in low-speed parades, in rally traffic or on long climbs on hot days. Motor oil plays a critical role in cooling these big air-cooled engines, and even more so in low-speed operation with limited wind generated to cool the bike. If the oil can’t withstand the heat, its ability to protect your bike is compromised.
AMSOIL Synthetic Motorcycle Oil Protects in Extreme Heat
To demonstrate its extreme-heat protection qualities, AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil was subjected to a dynamometer test designed to simulate conditions even more extreme than the demanding stop-and-go driving conditions of a motorcycle rally or parade route. A 2012 Harley-Davidson FXDB Dyna Street Bob* motorcycle equipped with AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil was subjected to a strenuous low-speed test cycle, with significant idle time broken by short bursts of engine revving and little to no air moving across the cylinders. 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 combination of low airflow and
inoperative temperature controls allowed the test lab to subject the oil and engine components to intense heat not normally experienced in the real world. Cylinder temperatures reached more than 500°F, and oil temperatures exceeded 300°F – temperatures well into the range where oils begin to break down and often lead to catastrophic failure.
500°F is No Problem
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 metals.
Your bike should never get this hot. If it does, AMSOIL has you covered. Find out what oils and filters your bike use from the application guide or ORDER NOW and get your bike ready for the riding season.
