Marine engines are commonly exposed to harsh conditions such as high loads, high speeds, and exposure to elevated levels of humidity and salt water. Boaters looking for the best protection for their engines can now use Royal Purple’s new line of NMMA FC-W Catalyst Compatible® multi-vis 30-weight and 40-weight, four-stroke High Performance Marine (HPM) engine oils.

Royal Purple is releasing a new line of motor oil aimed at the street/performance enthusiast market. For several years, the American Petroleum Institute (API) has been reducing the maximum limits of common anti-wear zinc/phosphorus anti-wear additives in motor oils via their self-governed licensing program. These changes have left many consumers struggling to find an alternative to the more expensive and difficult to find racing oils.
