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.

Affordable and Reusable
Size: 2.0L
The engine filter was really affordable it cost less then $15. I bought this filter because it was recommended from a family friend. It fitted my honda civic perfectly. Replacing the filter was so easy to replace. Replacing or changing the filter was easy it only took a few mins to do. The quality of the filter is really good and it feels like its perfect for my car. I would buy this filter over and over again thats how great it is.

Been buying these for years. They are relatively cheap and easy to replace, so much better than getting ripped off at the dealer lmao. Compatibility and Installation - 5/5 Filtration Efficiency and Performance - 5/5 Durability and Value for Money - 4/5 - these are made to be replaced, so can't really do much about that!
