100% Synthetic lubricant reinforced with Esters. Specially designed for powerful 4-Stroke snowmobile engines. Engineered to allow for faster REV raisings and maximum power output. Outstanding engine protection at high RPM and high temperature due to its high lubricity, corrosion protection and oxidative stability. The SAE 0W-40 viscosity grade corresponds to the most recent snowmobile manufacturers’ recommendations and improves engine start-ups in polar cold conditions while preventing wear.
