What is the difference between HPS® and Royal Purple® API-licensed motor oils?

Royal Purple API-licensed motor oil is formulated specifically to meet current American Petroleum Institute (API), International Lubricant Standardization and Approval Committee (ILSAC), and Association des Constructeurs Européens d’Automobiles (ACEA) specifications for new vehicle warranties. Over the last several years, these specifications have become increasingly restrictive on certain additives, particularly those commonly used for anti-wear. As such, API/ILSAC compliant oils aren’t the best solution for consumers that have modified their vehicles or those simply looking for the greatest performance.

HPS is formulated with consumers in mind. This motor oil line offers the incredible performance and protection provided by Royal Purple’s proprietary Synerlec technology as well as a dramatically enhanced anti-wear package. HPS is also the choice for those seeking to maximize horsepower and torque, while reducing wear, heat and fuel consumption. HPS is the most robust engine oil Royal Purple makes for non-racing applications.
