Classification
Product advantages:
This product is formulated using imported synthetic base oil with a high viscosity index ester and a composite additive package, providing power support for engines operating under ultra-heavy loads and continuous duty. It is suitable for Euro IV and Euro V engines.
Performance features:
High-quality, heavy-duty ester-based synthetic lubricant that enhances oil film strength, maintains stable oil pressure over time, and delivers effortless handling.
Excellent acid-neutralizing capacity, extending oil-change intervals and saving fuel;
Effectively controls engine sludge and high-temperature deposits from causing corrosion and wear to the engine.
Particularly suitable for providing excellent protection to heavy-duty, high-horsepower turbocharged diesel engines;
Usage:
New high-horsepower, heavy-duty, high-compression diesel engines (high-speed, turbocharged, or naturally aspirated).
Lubrication for large, heavy-duty container tractors and heavy-duty construction machinery equipped with diesel engines that meet stringent environmental emission standards applicable to Exhaust Gas Recirculation (EGR) systems and Diesel Particulate Filters (DPF).
