CJ-4 / 5W-30
Product Description
This product is a fully synthetic 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 CJ-4 specifications and is specifically designed for high-speed, four-stroke diesel engines equipped with advanced exhaust after-treatment systems (such as DPF, SCR, and EGR). It provides excellent protection against soot-related wear, oxidation, and catalyst poisoning.
Scope of application
Suitable for heavy-duty trucks, buses, and construction machinery equipped with advanced emission control systems (Euro V/VI or equivalent), requiring API CJ-4 performance. Ideal for engines operating under severe conditions with low-sulfur diesel fuel.
Product performance
Fully synthetic formulation provides outstanding thermal and oxidation stability, significantly extending oil 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 (thanks to synthetic base oil), ensuring easy cold starts in severe winter conditions.
Lower volatility and superior shear stability, reducing oil consumption and maintaining viscosity under high shear conditions.
