Premium Canadian-made BOSS Supreme full synthetic and synthetic-blend gasoline engine oils formulated to exceed API SP and ILSAC GF-7 standards. These oils are specifically engineered for modern turbocharged GDI/TGDI, small-displacement high-RPM, naturally-aspirated gasoline, and light-duty propane/natural gas engines in passenger cars, light trucks, SUVs, and high-performance vehicles. They deliver outstanding LSPI (low-speed pre-ignition) protection, maximum wear control, exceptional deposit/sludge prevention, superior oxidation stability, and excellent cold-weather performance – perfect for the harshest Canadian conditions.

All three grades provide proven protection against high-temperature oxidation, wear, rust, corrosion, and viscosity breakdown while keeping engines exceptionally clean and free of sludge/varnish deposits – even under severe turbocharged operating conditions.

✅ Key Benefits:

• Full LSPI protection for turbocharged GDI/TGDI engines
• Outstanding wear, rust, and corrosion protection
• Exceptional deposit & sludge control – engines stay cleaner longer
• Superior oxidation and thermal stability for extended oil life
• Excellent cold-weather flow and pumpability
• Enhanced fuel economy (especially 0W-20)
• Controls varnish deposits in high-temperature turbo operation
• Proudly formulated and bottled in Canada

✅ Grade-Specific Advantages:

• 0W-20 Full Synthetic → Ultimate cold-start protection and fuel economy. The top choice for Honda, Toyota, Hyundai, Kia, Mazda, and most vehicles requiring 0W-20 SP/GF-7 or dexos1 Gen 3.
• 5W-30 Full Synthetic → Maximum all-season protection and durability. Ideal for GM, Ford, Chrysler, turbocharged imports, and high-performance engines requiring 5W-30 SP/dexos1 Gen 3.
• 5W-30 Synthetic Blend → Premium partial-synthetic performance at real-world pricing. Perfect for older vehicles, fleets, daily drivers, and any application wanting modern SP-level LSPI protection without the full-synthetic price tag.
