Classification
Product advantages:
This product is formulated with imported high-viscosity-index ester synthetic base oil and a composite additive package. It is a high-quality diesel engine oil specifically designed for high-speed turbocharged engines, providing powerful support for heavy-duty, continuously operating engines and fully meeting the stringent Euro IV emission standards for vehicles.
Performance features:
Excellent high-temperature oil film strength enhances engine power output, maintains consistently stable oil pressure, and extends engine service life.
Effectively controls deposit formation in the valve and piston areas, reduces fuel consumption, exhibits excellent antioxidant stability and detergency-dispersancy, and extends oil change intervals.
Effectively protects the exhaust gas recirculation (EGR) system and provides lubrication protection for diesel engines meeting Euro IV and Euro V emission standards.
Usage:
Lubrication suitable for diesel engines meeting Euro IV and Euro V emission standards and equipped with exhaust gas recirculation (EGR) systems; lubrication for high-horsepower, heavy-duty diesel engines as well as luxury high-speed buses and heavy construction machinery.
