CNG/LNG/CF-4/SJ/SF/SE Natural Gas Engine Oil Additives

CNG/LNG/CF-4/SJ/SF/SE Natural Gas Engine Oil Additives For Lubricating Oils

When used in oil products, it exhibits good high temperature detergency, excellent anti-oxidation and anti-wear properties, and has low ash content.

It is suitable for lubrication of gas engines and gasoline engines.

Premium Additive Engine Oil for CNG/LNG Engines

Product Introduction

This premium additive engine oil solution is engineered for extreme gas combustion environments. Its optimized molecular structure delivers superior acid neutralization and deposit control in engines fueled by CNG, LNG, or biomethane, where conventional additives fail under high-temperature turbo stress.

Performance Advantages

Maintains viscosity integrity at 1,200°C turbo temperatures (40% lower carbon deposits vs. standard sulfonates per CEC L-101) .

Neutralizes nitric/sulfuric acids from lean-burn gas combustion (TBN retention ≥85% after 500h ASTM D7528).

Prevents saponification sludge in biomethane blends with ≤50 ppm siloxanes.

Ultralow ash (≤1.0%) and zero phosphorus preserve SCR/DPF systems .

This advanced additive engine oil chelates copper/lead ions to prevent bearing wear and sensor fouling, extending engine life in demanding gas engine applications.

Application
