    John Williams, Royal Purple's founding father, was the first to develop synthetic lubricants in the 1950s. When Mr. Williams retired in the 1980s, he continued to follow his passion for lubrication by serving as a consultant to many different oil companies. It was during that time when Williams was asked to solve constant bearing failures in the huge compressors of one company. Mr. Williams found out that there wasn't a lubricant that could cope with the demands of large equipment. So, he had to put his great background to create a new product that became the cornerstone of Royal Purple’s product line.

    John Williams developed a new additive technology (known as Synerlec) that fortified lubricants with a tenacious film in order to protect bearings under extreme loads. The technology also provided superior oxidation stability to prolong oil life. So, the new lubricant did solve the company's problems. Since the fluid was much better than anything else out there, it made sense to make it look different from other oils. Williams decided on the purple color and named the company Royal Purple. A long time ago, this color was extremely expensive to produce, and only royalty could afford the cost.
