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.

Great daily sunscreen with lightweight feel
Size: 1.7 Fl Oz (Pack of 1), Size: 1.7 Fl Oz (Pack of 1)
I’ve been using this sunscreen daily and I really like it. It feels very light on the skin, absorbs quickly, and does not leave a greasy or heavy feeling. It also works well under makeup and does not cause breakouts. I feel my skin is well protected from the sun and it’s gentle enough for everyday use. I highly recommend it for anyone looking for a reliable sunscreen.

Great for oily acne-prone skin
Size: 3 Fl Oz (Pack of 1)
I have oily, acne-prone skin, and this sunscreen has worked really well for me. It doesn’t feel overly greasy or too dry, and it sits nicely on my skin without making my face feel heavy. I’ve been using it for a long time, and honestly, it’s the only sunscreen I keep going back to because it works so well with my skin. It feels comfortable for daily use and gives good protection without causing extra breakouts for me.

Great for oily skin!
Size: 3 Fl Oz (Pack of 1)
Definitely leaves white cast, I’m pretty fair skinned, makes me look like a ghost. Just rub it in your hands first, breaks into the mineral so minimize the white cast look. It feels lightweight and as someone with pretty oily skin it does a pretty good job!

Great for Oily, Rash-Prone Skin, But Be Wary of the Residue
Size: 1.7 Fl Oz (Pack of 1)
This sunscreen is a really solid option if you have sensitive, rash-prone, and oily skin like mine. I’ve found it’s one of the few sunscreens that doesn't cause any irritation, which is a huge benefit for me. On top of that, it leaves a truly matte finish, so I don't feel greasy or shiny throughout the day. The only reason I can't give it five stars is that it leaves behind small, dried white bits on my face. They can be a bit annoying and make the application look a little messy. Overall, it's a good sunscreen that works well with my skin type, but the white residue is a definite drawback.

This stuff is magic!
Size: 1.7 Fl Oz (Pack of 1)
I farm and garden. I spend hours outdoors in the summer, and for years, I’ve hated wearing sunscreen because it made my face feel hot and sticky. This sunscreen is none of that. I received a small sample tube of it from the dermatologist and instantly fell in love with it. It goes on smooth and covers well. But the thing I love about it is that I don’t feel like I’m wearing sunscreen once it absorbs into my skin. I forget about it! It doesn’t combine with my sweat and run into my eyes, making them sting. It doesn’t irritate sensitive skin or clog my pores. This stuff is magic and I will be using it daily. It’s not the least expensive sunscreen out there, but it’s worth it!
