Product Advantages: This product is formulated with imported, high-viscosity-index ester-based fully synthetic base oil and a composite additive package. It delivers all-around performance in a premium formulation, providing long-lasting protection that keeps your engine running like new even under heavy loads. It’s ideal for high-performance, heavy-duty trucks and engines meeting Euro V and Euro VI emission standards. Performance Features: High-quality, fully synthetic diesel engine oil based on esters, forming an instant protective film, maintaining stable oil pressure over time, and ensuring effortless handling. Specifically designed to meet the latest exhaust particulate emission standards, this oil offers exceptional protection for new low-emission engines using ULSD (Ultra-Low Sulfur Diesel). It complies with the requirements of engines equipped with EGR and DPF systems and provides superior lubrication and protection even under the harshest operating conditions. Applications: Suitable for ultra-heavy-duty, high-compression diesel engines, including those equipped with Exhaust Gas Recirculation (EGR) systems and Diesel Particulate Filters (DPF), as well as for large, heavy-duty container tractors and heavy-duty construction machinery engines that meet stringent environmental emission standards. Recommended for use in both naturally aspirated and turbocharged diesel engines. Developed in accordance with the latest emission standards, it is particularly well-suited for off-road and construction vehicles, as well as for large commercial road transport vehicles—including those with newly electronically controlled engines.
