YEFE Endurox FLD 10W-40 is an extra high performance full synthetic heavy-duty diesel engine oil engineered for modern, high-output, low-emission diesel engines. Formulated with state-of-the-art additive technology and hydroprocessed base oils, it delivers outstanding engine protection, cleanliness, and long service life for both new-generation and older heavy-duty diesel engines operating under demanding workloads and emission-regulated environments.

This oil meets Euro IV, V, and VI as well as US 2007 on-highway emission standards and exceeds API CK-4 requirements, making it a versatile and highly capable choice for commercial transport, heavy-duty trucks, and off-highway machinery equipped with exhaust after-treatment devices such as DPF, SCR, and EGR systems. Its low ash formulation minimizes particulate buildup in diesel particulate filters, while exceptional TBN retention and superior dispersant and detergent properties maintain engine cleanliness and extend oil drain intervals, helping to reduce maintenance costs and maximize operational uptime.

YEFE Endurox FLD 10W-40 is built with advanced additive chemistry and severely hydroprocessed synthetic base oils to deliver extra high performance across a broad range of heavy-duty diesel engine applications. Its full synthetic formulation provides excellent thermal and oxidation stability, a very high viscosity index with outstanding shear resistance, and strong protection against bore polishing, wear, corrosion, and foam formation, ensuring reliable performance across a wide temperature range.

The oil’s low ash content protects diesel particulate filters and other exhaust after-treatment components from premature clogging, extending their service life and supporting compliance with modern emission regulations. Superior dispersant and detergent properties keep engine internals clean by preventing sludge and deposit buildup, while exceptional TBN retention provides continuous protection against corrosive combustion by-products over extended drain intervals. With approvals from major OEMs including Volvo, Mack, Cummins, DAF, IVECO, MAN, Deutz, and MTU, YEFE Endurox FLD 10W-40 delivers broad compatibility and reliable performance across a wide range of commercial and industrial heavy-duty applications.
