High-performance synthetic oil for heavy-duty engines with advanced protection features.
Royal Purple Duralec Ultra motor oil is engineered to enhance the performance of modern heavy-duty engines. This synthetic oil is formulated with a high concentration of zinc and phosphorus anti-wear additives, along with Royal Purple's proprietary Synerlec technology. Synerlec forms a strong ionic bond with metal surfaces, ensuring protection during startup and significantly increasing film strength to prevent metal-to-metal contact under extreme conditions.
Duralec Ultra is designed to minimize parasitic loss, contributing to fuel savings while its synthetic solvency effectively keeps engine components cleaner than traditional detergents. The oil's superior oxidation resistance extends drain intervals and reduces oil degradation, making it a reliable choice for both two-cycle and four-cycle diesel applications. It is suitable for automotive, commercial fleet, and stationary industrial diesel engines, providing versatility and performance in various settings.
