1. Revolutionary friction control system
- Molybdenum Nano Technology: Micro-dispersed molybdenum compounds form an elastic protective layer on the engine surface, reducing metal-to-metal contact by up to 40% compared to conventional SL oils
- Cold Start Optimization: Special low temperature additives ensure immediate lubrication as soon as the engine is started, when 75% of wear typically occurs.
2. Advanced Deposit Control
- Triple Action Cleaner: A unique combination of cleaners proactively removes existing deposits while preventing the formation of new sludge.
- High Temperature Stability: maintains viscosity integrity even in turbocharged engines running at extreme temperatures
3. Enhanced Long Lasting Components
- Antioxidants: Extend oil change intervals by resisting chemical decomposition up to 30% longer than the minimum standard required
- Acid Neutralizer: protects bearing surfaces from corrosive wear during stop-and-go driving conditions
Suitable for high performance engines:
- Prevents viscosity shear under high RPM operation
- Prevents turbocharger bearing coking
Suitable for older vehicles:
- Extra seal conditioner prevents leakage of aged gaskets
- Downward compatible with SJ/SH specification
Suitable for extreme conditions:
- Cold start at -35°C (5W-30 rating)
- Can be towed/hauled in thermally stable conditions above 150°C
✅ Laboratory-proven: Simulated engine tests over 20,000 km have shown wear to be 60% lower than API minimum standards
✅ Fuel Economy Certified: meets ILSAC GF-3 standards for improved mileage
✅ Emission System Safety: Low phosphorus formulation protects catalytic converters
- Normal maintenance: 6,000-7,000 km replacement
- First time use: Flushing from a low grade oil change is recommended.
Designed for drivers looking for superior performance, our SL-grade oils offer professional-grade protection at consumer prices. Available in 1-liter, 4-liter and 20-liter industrial packs with optional dispensing systems.
Our motor oils carry dual API SL/CF certification, making them suitable for both gasoline and light diesel engine applications.
We offer two viscosity options: a 5W-30 premium synthetic blend and a 10W-40 high mileage formulation to meet different engine requirements.
It forms an elastic protective layer on the engine surfaces that reduces metal-to-metal contact by up to 40% compared to conventional SL oils, minimizing wear significantly.
For normal vehicle maintenance, we recommend replacing the engine oil every 6,000 to 7,000 kilometers.
Yes. The 5W-30 grade supports cold starts down to -35°C, and the oil remains thermally stable even under demanding towing or hauling conditions exceeding 150°C.
Yes, it features a low phosphorus formulation specifically designed to protect and extend the life of your catalytic converters.
