TD Obsolete Designed for water-cooled outboard engines, this classification used the identical engine test to that in the National Marine Manufacturers association (NMMA) TC-W category. Two-cycle engine oils designed for API Classification TC address ring-sticking, pre-ignition and cylinder scuffing problems. TC Current Designed for various high-performance engines, typically between 200 and 500 cc, such as those on motorcycles and snowmobiles, and chain saws with high fuel-oil ratios - but not outboards. The test sponsor no longer requires this category, and the classification has been abandoned. TB Obsolete Proposed classification for two-stroke engine oils required for the engines of motor-scooters and other highly-loaded small engines, typically between 50 and 200 cc. Engine Tests for this classification were under preparation when the Coordinating European Council (CEC) withdrew support for this category. TA Obsolete Proposed classification for two-stroke engine oils required for extremely-small engines, typically less than 50 cc. So I guess it could be broken down as FB=dirty, FC=clean, FD=very clean.

FD has much higher detergency than FB or FC, plus a lower allowed amount of sulfated ash. So FB, FC, and FD have the same lubricity and initial torque requirements, but FC and FD have lower exhaust system deposits and smoke, and higher detergency. I believe JASO FC and FD are allowed to be labeled as 'smokeless'. Same as FC with far higher detergency requirement. Lubricity and initial torque requirements same as FB, however far higher detergency, exhaust smoke and exhaust system blocking requirements over FB. Increased lubricity, detergency, exhaust smoke and exhaust system blocking requirements over FA. Original spec established regulating lubricity, detergency, initial torque, exhaust smoke and exhaust system blocking. Therefore the Japanese Engine Oil Standards Implementation Panel (JASO) introduced the following specifications: Quicksilver TC-W3 2-Stroke Oil 4Ltr - A premium oil for 2-cycle outboard engines providing superior high temperature cleanliness & all round protection from.

Oils meeting the API TC standard still produced excessive smoke and could not prevent exhaust blocking. Japeneese motorcycle manufacturers found the limits demanded by the API TC specifications too loose.

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 Fx. An two stroke engine oil is granted the official JASO seal if it has been independently tested. The different quality levels set requirements with regards to properties such as minimum lubrication, minimum detergency, maximum smoke and maximum deposits. It was revised in 2004 as JASO M345:2004 which discontinued the FA level, and introduced the new JASO FD level - the FD level supersedes JASO FC as the highest rating. It was introduced by the Japanese Automotive Standards Organization (JASO) in 1994 as JASO M345-93 with the quality levels JASO FA, JASO FB and JASO FC - with FC setting the highest standard. JASO M345 is a quality classification standard for two stroke engine oils for engines of Japanese origin.
