The introduction of the world’s first synthetic motor oil to meet American Petroleum Institute service requirements in 1972 set all-new standards for motor oil quality. AMSOIL synthetic motor oil outperformed conventional petroleum motor oils on all counts. It was clear from the start that this innovative product would play a major role in engine performance and engine life.
The tradition of innovation and technological advancement continues with AMSOIL synthetic lubricants for dirt bikes. Hours of testing in AMSOIL chemical and mechanical labs resulted in lubricants engineered to maximize your bike’s performance on the trail and at the track. Testing with professional teams in Monster Energy Supercross, AMSOIL Arenacross and AMSOIL GNCC helped further fine-tune AMSOIL Synthetic Dirt Bike Oil for outstanding wear protection and consistent clutch feel. AMSOIL Synthetic Dirt Bike Oil delivers the confidence and performance you need to get on it and get out front.
