6X Better Protection than Harley-Davidson

What good is all the power your V-twin delivers if your oil can’t handle the heat? Extreme heat can cause oil to lose viscosity and become thinner, reducing protection and leading to poor shifts or compensator noise. We formulate AMSOIL Synthetic V-Twin Motorcycle Oil to fight extreme heat and stress in the toughest conditions. In fact, industry-standard testing shows that AMSOIL resists viscosity breakdown six times better than Harley-Davidson* SYN3* for improved protection against compensator and transmission gear wear. Protect your bike and the spirit of the American biker. Upgrade to AMSOIL protection in your V-twin.
