FOR THE LIFE OF YOUR RIDE
ONLY THE BEST WILL DO
To create the best oil for any terrain, we invest
in rigorous testing to ensure our oil delivers the
consistency and performance you demand. The
results are Polaris Engineered Lubricants that
are tested and perfected to deliver excellent
total engine protection for the life of your ride.

WHAT COUNTS IN OIL TESTING:
1. Does it protect the engine at high temperatures?
2. Does it keep the engine free from carbon and buildup?
3. Does the oil hold its viscosity over time?
