Product Overview
AGREX Heavy-Duty Diesel Engine Oils are formulated with high-quality group II/group III base oils and advanced low-SAPS (Sulphated Ash, Phosphorus, and Sulphur) additive technology. Engineered to exceed the performance requirements of API CK-4, CJ-4, and CI-4 standards, these oils deliver outstanding soot dispersion, wear protection, and shear stability. They are designed for modern diesel engines equipped with exhaust after-treatment systems such as Diesel Particulate Filters (DPF), Selective Catalytic Reduction (SCR), and Exhaust Gas Recirculation (EGR).
Key Features & Benefits
- Advanced Soot Control: Prevents soot aggregation, preventing oil thickening and abrasive wear.
- Exhaust After-treatment Protection: Low-ash chemistry prevents DPF clogging, ensuring long catalyst lifespan.
- Thermal Stability: Resists oil oxidation and thermal breakdown, enabling extended oil drain intervals.
- Piston Cleanliness: Actively cleans pistons, preventing ring sticking and maintaining engine compression.
Applications & Suitability
- Heavy-duty commercial vehicle truck fleets, public buses, and local transport fleets.
- Off-highway machinery in construction, road-building, mining, and quarrying.
- Modern agricultural tractors operating under heavy field loads.
- Industrial diesel generator sets (DG sets) requiring continuous duty protection.
