Duralec Ultra combines premium base oils with Royal Purple's proprietary additive technology, Synerlec, to create a high-performance motor oil that optimizes engine performance and provides superior protection in rigorous on/off highway applications. Synerlec provides unsurpassed film strength and lubricity – up to 4X more than top competitors. In addition, advanced synthetic solvency reduces engine deposits and keeps engines clean. The net result is a better performing engine, with reduced downtime and lower cost of ownership. Royal Purple recommends for use in a variety of heavy-duty applications including commuting, over-the-road trucking, agriculture, construction and mining.
Royal Purple located in Porter, Texas, produces a wide range of high performance lubricants for nearly every consumer and industrial application. Royal Purple?s founder John Williams was a pioneer in the development of high performance synthetic lubricants and collectively, Royal Purple?s formulators have more than 200 years of expertise in developing high performance lubricants. Royal Purple focuses exclusively on developing state-of-the-art lubricants. Unlike companies that primarily focus on fuel and other petroleum byproducts, Royal Purple?s sole mission is to develop products that significantly outperform other synthetic and mineral based oils.
