I found this information for another web site forum, I thought it might be helpful here.
With the widespread introduction of the four-stroke outboard engine technology, NMMA considered it necessary to develop a marine engine oil category specifically for marine four-stroke engines. With all of the major outboard engine manufacturers producing four-stroke outboards to further reduce emissions and increase fuel economy, the need for oil specifically designed for the unique marine environment became necessary. FC-W™ lubricants have demonstrated the necessary performance and quality needed need in today’s high performance four-stroke engines. The next time you are purchasing four-stroke oil for your marine engine, look for the FC-W™ trademark.
