LeMans

With the strongest of film strengths and durability of Royal Purple oils, this year they stood the challenge and supplied race teams for the French LeMans 24 hr endurance. Testament to the quality of the oil. Performance car oils

Transmission builders

Royal Purple has become a vital component for some of the UK's leading engine & transmission builders.
Royal Purple Max gear also comes recommended by Hewland Transmissions and Glebe Transmissions, and is currently being fitted to the American road going Mosler supercars (just like the one that dominated the British GT Championships last year), which are now being produced in the UK. Max Gear

Embassey Racing

Royal Purple fully synthetic racing oils are widely used in the British Formula 3 championship, and are now being used by teams like Embassy Racing in the British GT Championship.

Damax

Royal Purple is also fully endorsed & recommended by former Ferrari Marinello champions Damax Racing, who use it in all their race & road going cars. Royal Purple oils

Ford

Ford Motor Company was experiencing problems with their Ford Puma rally engines, which was being caused by poor lubricant life. They changed to Royal Purple, and instead of changing the oil frequently through the rally, they were able to run for several rallies on the same sump full of Royal Purple oil. Transmission oils

Royal Purples History

Royal Purple was founded in 1986, but its roots go back much further. Founder John Williams was a pioneer in developing synthetic lubricants as far back as the 1940s and 1950s. He used his expertise in chemical engineering to found two other successful lubricant companies prior to founding Royal Purple.

Mr. Williams had officially retired in the 1980s, yet he continued to pursue his passion for lubrication by serving as a consultant to numerous companies. In 1986 an oil production company asked Mr. Williams to solve chronic bearing failures in their large compressors. Mr. Williams found that there was simply not a lubricant available that could handle the demands of the equipment. He immediately began to put his extensive lubrication background to work with long hours and late nights in the lab. The result of his efforts was the development of a new lubrication technology.

Mr. Williams' new lubricant had unusually high film strength capable of protecting bearings under heavy loads. It also had exceptional oxidation stability (for long oil life) while providing outstanding protection against rust and corrosion in both wet and high temperature applications. The new lubricant would not only prevent varnish and sludge, but also clean the equipment in the process. It extended oil drain intervals and the life of the equipment while reducing maintenance costs, equipment downtime, and energy costs, resulting in dramatic savings.

Mr. Williams' new lubricant easily solved the oil product company’s equipment problems. When the company’s plant manager tried the oil, he said that it was so superior to anything he had tried before that it shouldn’t even look like other lubricants.

Mr. Williams offered to make it red, green or blue, but the customer had seen those before. The customer said he had never seen purple oil, so Mr. Williams elected to make the lubricant purple. That lubricant, called Synfilm®, along with its exclusive, proprietary Synerlec® additive technology, became the cornerstone of Royal Purple’s entire line of high performance industrial, automotive and racing oils.

Mr. Williams decided to name the company Royal Purple since historically, royalty used the color purple for only the finest of fabrics because it was so expensive to produce. Mr. Williams’ hope was that the color's association with quality would symbolize the quality in all of Royal Purple's lubricants.

Today, Royal Purple continues to commit significant resources into research and quality assurance to ensure that it continues to raise the standard of excellence in lubrication.

Feel the Difference

The most frequent comment from customers is how they can feel the difference in their vehicles after switching to Royal Purple. For instance, Royal Purple® Motor Oil typically improves horsepower and torque up to 3%. It also reduces fuel consumption by as much as 5% and typically reduces emissions 20% or more. Performance gains will vary depending on the type of vehicle, its condition, and the way it's driven. Visit our test summary page for independent test results that document these performance gains.

Superior Technology

Synerlec® is Royal Purple's proprietary, lubricant technology that strengthens the oil to provide unmatched performance and protection. It also creates an ionic bond that adheres to metal parts for continuous protection, even after shutdown. Synerlec® is the cornerstone of Royal Purple's automotive products.
Royal Purple and fuel savings

Film Strength

Film strength is a lubricant's ability to prevent contact between metal parts. Royal Purple's film strength is up to 400% stronger than other oils. This improves combustion for more power, better fuel economy and reduced emissions. High film strength also helps to dramatically reduce wear. According to the editors of Hot Rod magazine, We've torn down some of our dyno engines that have been seriously abused, but with Royal Purple) in the pan, the bearings have looked new.

Friction

The primary purpose of oil is to reduce friction. Reducing friction increases horsepower and torque, and reduces fuel consumption, emissions, engine wear and heat. Royal Purple uses premium base oils with a very low coefficient of friction. Royal Purple also smoothes metal surfaces to further reduce friction. Royal Purple remains on the metal surface long after ordinary lubricants would have been squeezed out by pressure and heat. The oil layer responds to increased pressure with increased viscosity until the metal peaks (asperities) undergo deformation and flow into the low spots. Over time, the metal surface becomes extremely smooth and can even develop a mirror-like surface.

Notice that after using Royal Purple® the bearing surface is now significantly smoother than it originally was. Smoother surfaces reduce friction for improved performance.

Increased oil life

Lubricants often have a service life of only 3,000 miles due to oxidation which reduces oil's ability to lubricate. Oil's ability to resist oxidation is measured by the ASTM's rigorous Thin Film Oxidation Uptake Test (TFOUT). The test is so severe that it lasts only 1300 minutes. Royal Purple not only surpasses leading mineral- and synthetic-based oils in the test, it also outlasts the duration of the test.

Royal Purple's superior oxidation stability enable oil changes to be extended up to 12,000 miles (or more depending on the equipment), saving money, saving time and reducing the amount of used oil that must be disposed of.
