Increased shear stability for better viscosity control and optimal engine oil pressure. Multi-functional dispersant additives provide an enhanced level of protection against the effects of soot, dirt, and other contaminants compared to previous formulation.
Full synthetic 15w-40 diesel engine oil with Triple Protection Plus technology protects against wear, deposits, oil breakdown, and improves low-temperature flow. Advanced low ash formulation helps protect the exhaust catalysts and particulate filters found on the latest low-emission vehicles. Better cold-cranking properties and low-temperature pumpability for reaching critical engine parts faster.
