JASO FC is a rating for a grade of oil.

Oils are granted the JASO FC certification by the Japanese Automotive Standards Organization. JASO FC is the highest rating for 2-stroke oils. JASO-FC oils leave little deposits and create very little smoke. They also pass lubricant and detergent tests. A JASO FC oil will have a rectangular seal. In the upper quarter of the rectangle will be a serial number and the lower three quarters will just have the letters M.

Again, there is an official JASO seal if the oil has been independently tested. The seal is a rectangle; in the upper quarter of the rectangle will be a serial number, and the lower three quarters will just have the letters MA.
