Premium Canadian-made BOSS GL-5 gear oils – choose full synthetic grades (75W-90 and 75W-140) for superior flowability, minimized gear wear, reduced frictional drag, and protection against heavy loading failures in extreme weather, or the conventional 80W-90 for outstanding thermal stability, corrosion/rust protection, and superior seal compatibility in standard applications. All grades are formulated with high-quality base stocks and sulfur-phosphorus extreme pressure (EP) additives to deliver exceptional anti-wear, anti-scuffing, and anti-pitting performance in hypoid differentials, limited-slip units, manual transmissions (non-synchronized), rear axles, and final drives under high-shock, high-torque, and severe-service conditions – perfect for automotive, truck, off-road, and industrial gear systems in harsh Canadian climates.
Provide reliable protection against thermal breakdown, oxidation, foam, and deposits while ensuring smooth operation, extended component life, and compatibility with limited-slip additives.
✅ Key Benefits:
- Extreme pressure (EP) additives protect against scuffing, scoring, pitting, and heavy shock loads
- Outstanding thermal and oxidation stability – resists thickening and sludge formation
- Superior rust, corrosion, and foam inhibition
- Excellent seal compatibility to prevent leaks and extend seal life
- Limited slip capable – suitable for LSD differentials without additional modifiers
- Superior low-temperature fluidity (synthetics) for cold-weather performance
- Ensures top-notch field performance in extreme hot/cold conditions
- Proudly formulated and bottled in Canada
✅ Grade-Specific Advantages:
- 75W-90 Synthetic → All-season versatility with excellent cold-flow (-51°C pour) and reduced drag – ideal for passenger vehicles, light trucks, 4x4s, and trailers in variable climates.
- 75W-140 Synthetic → Thicker film strength for extreme heavy-duty, high-heat, and towing applications – maximum protection in racing, off-road, and severe service.
- 80W-90 Conventional → Reliable value-priced option for standard differentials and transmissions – proven in automotive, truck, and rear axle applications requiring GL-5.
