Premium Canadian-made BOSS full synthetic extreme-pressure multi-grade gear lubricant engineered to exceed API GL-5 and API MT-1 performance requirements. Formulated for severe-service applications in heavy-duty and high-performance differentials (including limited slip), manual transmissions, hypoid gears, and final drives operating under high shock-load, high-torque, high-speed, or low-speed/high-torque conditions – perfect for trucks, 4×4s, towing, off-road, racing, and any equipment that demands maximum gear protection in the harshest Canadian climates.
Delivers outstanding thermal stability, superior oxidation resistance, exceptional shear stability, and extended drain capability while providing complete protection against wear, scuffing, spalling, pitting, scoring, and corrosion – even in extreme temperatures and extended service intervals.
✅ Key Benefits:
- Full synthetic PAO base stocks for superior cold-flow and high-temperature performance
- Extreme pressure (EP) chemistry protects against shock loading and scuffing
- Limited slip capable – no additional friction modifier required
- Outstanding shear stability – stays in grade longer
- Exceptional thermal & oxidation stability for extended drain intervals
- Superior low-temperature fluidity (pours at –45°C and below)
- Excellent seal compatibility and corrosion protection
- Reduces operating temperatures and extends component life
- Proudly formulated and bottled in Canada
