Premium Canadian-made BOSS 50/50 prediluted antifreeze/coolants – choose from traditional Universal Green (conventional hybrid technology) or advanced Extended Life Red (long-life OAT formula). Both are ready-to-use ethylene glycol-based coolants pre-blended with high-purity deionized water and pre-charged SCA (Supplemental Coolant Additive) packages to deliver superior year-round freeze/boil-over protection, outstanding corrosion inhibition, and extended water pump life in passenger cars, light trucks, SUVs, heavy-duty diesel, fleet, agricultural, and off-road equipment – even under the toughest Canadian winter and summer conditions.

Both formulas provide proven protection against rust, corrosion, cavitation, liner pitting, scale buildup, electrolysis, and overheating while maintaining excellent heat transfer and compatibility with all cooling system metals (aluminum, brass, copper, solder, steel, cast iron) and gasket/seal materials.

✅ Key Benefits:

  • Ready-to-use 50/50 – just pour, no mixing required
  • Freeze protection down to –37°C / boil-over protection to +127°C (with 15 psi radiator cap)
  • Pre-charged SCA for immediate heavy-duty diesel protection
  • Superior multi-metal corrosion protection – including aluminum wet-sleeve liners
  • Excellent water pump lubrication and extended seal life
  • Prevents scale, deposits, and foaming
  • Outstanding heat transfer properties
  • Compatible with all conventional hoses and seals
  • Proudly formulated and bottled in Canada

✅ Formula-Specific Advantages:

  • Universal Green → Traditional hybrid inhibitor package with broad compatibility – safe to mix with or top-up any colour conventional coolant. Perfect for older vehicles, mixed fleets, farm/off-road equipment, and any system requiring conventional green coolant or heavy-duty SCA pre-charge.
  • Extended Life Red → Advanced extended-life organic acid technology with 5-year/400,000 km service life rating. Superior long-term aluminum protection, meets CAT EC-1 spec, ideal for modern engines, extended drain intervals, heavy-duty fleet, and equipment that demands maximum uptime and reduced maintenance.

Comfortable Shoes Right Out of the Box
Size: 9, Color: Black
I bought these shoes for my husband. He has a very hard time finding quality, comfortable shoes. These shoes are just as comfortable as his New Balance. He uses them as a dress shoe and wears them at least once a week. There was no break in period necessary. They were comfortable right out of the box! The only thing we didn't like was the white sole color. Once I knew he was going to keep them, I used a black sharpie marker to color the soles black. Instant amazing, comfortable dress shoes. They were well worth the cost. If you or your SO needs a comfortable pair of shoes, we highly recommend them.

Paid for new, received used.
Size: 9.5 Wide, Color: Cognac, Size: 9.5 Wide, Color: Cognac
Arrived dirty as if someone whore it for more than a few days. Maybe I was mistaken, but I saw nothing about “previously used” on the Amazon page. Returned it. I would suggest that the company use quality control when it comes to shipping. The shoes seem find otherwise. I ordered 9.5 and it was just a bit tight. If I reorder I will go for size 10.

Decent Shoes with Misleading Description (Not Leather)
Size: 12 Wide, Color: Black, Size: 12 Wide, Color: Black
I only look for leather when I’m purchasing dress shoes. Under the description “details” on this item it lists the shoe as leather upper and inner lining. A photo shows “genuine Napa leather lining”. If you keep reading (which I have now that I’ve received the shoes) it shows “faux leather” in the small print and that is not “leather”. I run a small leather business and this irks me because it’s clearly false advertising. The details also show the product is made in Brazil but when they arrived today, the shoe tag shows “Made in China” and “Man Made upper and lower”. I don’t hate the shoes. They look nice. What I know is they won’t hold up over time like leather, which is why the description should be accurate and not misleading.
