What is the difference between HPS and Royal Purple’s API-licensed engine oils?
Royal Purple’s API-licensed engine oils are formulated specifically to meet current American Petroleum Institute (API), International Lubricant Standardization and Approval Committee (ILSAC), and Association des Constructeurs Europens d’Automobiles (ACEA) specifications for new vehicle warranties. Over the last several years, these specifications have become increasingly stringent on certain additives, particularly those commonly used for anti-wear. As such, the new warranty restrictions aren’t the best solution for consumers that have modified their vehicles or those simply looking for the greatest performance. HPS is formulated with these consumers in mind and includes 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.
