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, propane, and natural gas engines in passenger cars, light trucks, SUVs, motorcycles, 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 and high-temperature turbo operation.

All 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 operating conditions. Full synthetic grades use premium Group III base stocks for ultimate thermal stability and extended drains, while synthetic blends offer excellent performance at a value price.

✅ 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 lower viscosity grades)
  • Controls varnish deposits in high-temperature turbo operation
  • Recommended for domestic and foreign high-performance engines
  • Proudly formulated and bottled in Canada

✅ Grade-Specific Advantages:

  • 5W-20 Synthetic Blend → Excellent all-season protection and value – ideal for Honda, Toyota, Hyundai, Kia, and vehicles requiring 5W-20 SP/GF-7 or dexos1 Gen 3.
  • 5W-30 Synthetic Blend → Premium partial-synthetic for daily drivers and fleets – perfect for GM, Ford, Chrysler, and imports needing 5W-30 SP with LSPI defense.
  • 10W-30 Synthetic Blend → Robust protection for warmer climates and older engines – suits high-mileage vehicles, light trucks, and equipment requiring 10W-30 SP.
  • 10W-30 Full Synthetic → Maximum durability for high-RPM and turbo applications – great for performance engines and severe service needing 10W-30 SP.
  • 5W-20 Full Synthetic → Ultimate cold-start flow and fuel economy – top choice for modern vehicles specifying 5W-20 SP/GF-7 or dexos1 Gen 3.
  • 5W-30 Full Synthetic → Superior all-season performance and protection – the go-to for turbocharged imports, high-performance, and engines requiring 5W-30 SP/dexos1 Gen 3.

Really nice watch!
Color: 3675 ALL Black
Really nice and clean looking watch. Fairly easy to adjust the watch band, with a little patience. Item description stated battery operated, but I don’t think it is as there is no indication that it has a battery in it. Other than that, really decent watch! I would have given it a five star rating if it were battery powered.

Great price
Color: 3675 Silver Grey
The watch looks like it should cost more than the actual price. It catches people's eye and so far it keeps accurate time. Keep in mind I've only had the watch about two weeks. Of my 10 every day watches this one is the most attractive.

Good attractive value
Color: 3676 ALL Black
This watch is a very good value imo. Looks like a quality watch. Band is adjustable and comes with a tool to assist in removing band pins. Keeping time very good. I would buy it again and will buy another in a different style

Within two weeks of normal wear, the watch quit keeping time and the band broke. Returned for a refund.
