CI-4/CH-4/CF-4/CD/SF/SG/SJ/SL Engine Additive For Engine Oi

CI-4/CH-4/CF-4/CD/SF/SG/SJ/SL Engine Additive

CI-4/CH-4/CF-4/CD/SF/SG/SJ/SL Additive for Engine Oil Diesel Fuel Lubricant Additive

Advanced protection for gasoline and diesel engines

This advanced additive for engine oil has been developed to formulate high quality automotive engine oils and multigrade oils. It is an advanced lubricant additive package engineered for formulating CI-4/CH-4/CF-4/CD/SF/SG/SJ/SL grade diesel engine oils.

Product Introduction

This additive for engine oil combines synergistic detergent, dispersant, and anti-wear technologies to address severe soot contamination, high-temperature deposits, and acid corrosion in modern heavy-duty engines. Ideal for extended-drain intervals and low-emission systems, it ensures optimal engine protection under extreme loads and EGR (Exhaust Gas Recirculation) conditions.

Key Features

Utilizes polyisobutylene succinimide-aromatic amine dispersant technology to inhibit soot agglomeration, maintaining 100°C kinematic viscosity stability even at >3.8% soot levels (critical for CH-4/CI-4 compliance).

Limits viscosity increase to ≤2.32 mm²/s at 3.8% soot—far below CH-4 specifications (≤11.5 mm²/s).

Multi-component antioxidant system (including ZDDP and auxiliary agents) minimizes oil degradation and sludge formation under sustained high temperatures (≤300°C).

Reduces piston deposits by >40% compared to conventional additives, ensuring engine cleanliness.

Optimized ZDDP (Zinc dialkyldithiophosphate) and calcium sulfonate detergent blend prevents bearing lead corrosion, scuffing, and micropitting.

Protects critical components (turbochargers, injectors) in high-sulfur fuel environments.

Neutralizes acidic byproducts from EGR systems and biofuels, extending oil life and DPF (Diesel Particulate Filter) durability.
