Recommended Oil for Can-Am Defender
The manufacturer recommends BRP XPS 4-Stroke Synthetic Oil 5W-40, designed specifically for Rotax engines. This oil offers excellent protection under extreme conditions, prevents engine wear, and ensures smooth performance.
However, if you can’t find BRP oil, there are equivalent high-quality synthetic oils that meet or exceed the manufacturer’s requirements. Always use API SM or higher certified 4-stroke oil and avoid automotive oils that contain friction modifiers, which can damage wet clutch systems.
