Premium SL Gasoline Engine Oils from China Suppliers - Advanced Factory Protection for Modern Engines
Breakthrough Performance Characteristics
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

Frequently Asked Questions
Q1: What does the API SL specification mean for my engine?
API SL is an engine oil service category designed to provide better high-temperature deposit control and reduced oil consumption. It is highly suitable for passenger cars and light trucks built in 2004 or earlier, and offers backward compatibility for older engines.
Q2: Can I use this SL oil in both gasoline and diesel vehicles?
Yes. Thanks to its dual-grade API SL/CF certification, this motor oil is engineered to perform exceptionally well in gasoline engines while also meeting the requirements for light diesel engines.
Q3: How does Molybdenum Nano Technology reduce engine wear?
Our micro-dispersed molybdenum compounds create an ultra-thin, highly elastic chemical barrier on internal metal surfaces. This significantly reduces direct metal-to-metal contact by up to 40%, protecting vital parts during cold starts and high-load operations.
Q4: Which viscosity grade should I choose: 5W-30 or 10W-40?
The 5W-30 synthetic blend is optimized for modern cars requiring excellent low-temperature fluidity and cold start protection down to -35°C. The 10W-40 formulation is a high-mileage option designed with extra seal conditioners to prevent leaks in older engines.
Q5: Why is flushing recommended when switching to this motor oil for the first time?
If your engine previously used a lower-grade or highly oxidized oil, flushing helps remove existing sludge, varnish, and acidic residues. This ensures that the advanced additive package in our SL oil can perform at its maximum efficiency.
Q6: Is this oil safe for vehicles equipped with catalytic converters?
Yes, our SL motor oil is formulated with balanced phosphorus levels. This low-phosphorus composition provides robust anti-wear protection via ZDDP while preventing catalytic converter poisoning and maintaining emission system efficiency.
