CK-4 / 5W-30
Product Description
This product is a fully synthetic extended-drain heavy-duty diesel engine oil, blended from high-quality synthetic base oil sourced from Sinopec and advanced low-SAPS (Low Sulfur, Ash, Phosphorus) additive packages from Afton and Infineum. It meets API CK-4 specifications and is specifically designed for modern high-performance diesel engines equipped with advanced exhaust after-treatment systems (such as DPF, SCR, and EGR).
Scope of application
Suitable for heavy-duty trucks, buses, and construction machinery meeting Euro V/VI or equivalent emission standards (National V/VI) that require API CK-4 performance. It is also suitable for engines using low-sulfur diesel fuel and biodiesel blends.
Product performance
Fully synthetic formulation provides outstanding thermal and oxidation stability, supporting extended drain intervals.
Excellent low-ash formulation, effectively protecting DPF (Diesel Particulate Filter) and SCR systems from clogging.
Outstanding soot dispersancy, effectively controlling soot-related viscosity increase and maintaining engine cleanliness.
Excellent anti-wear and extreme-pressure performance, effectively protecting cylinder liners, pistons, and valve train components.
Superior low-temperature fluidity and lower volatility, ensuring easy cold starts and reduced oil consumption.
Excellent shear stability, maintaining viscosity grade under severe high-shear conditions.
Technical specifications
Conform to GB 11122 (Diesel Engine Oils) and API CK-4.
Fully Synthetic.
Available viscosity grades: 5W-30, 5W-40, 10W-40.
