We’ll also explain the JASO standardization system and the different JASO standards mean. Let’s dive in!

What Is JASO M435 Standardization

JASO is short for the Japanese Automotive Standards Organization. JASO came up with their own qualification standard for engine oil called JASO M345. JASO M345 judges the performance of 2 stroke engine oils for engines that are made in Japan.

The accepted standard for measuring 2 stroke engine oils was API TC. This wasn’t a very good standard as it didn’t measure excess smoke and exhaust blockage. A better system was required and JASO came into action.

JASO started in 1994. Three standards were introduced – JASO FA, JASO FB, JASO FC. JASO FC was the highest standard and the best oil was selected in this category.

The JASO standards were revised in 2004 and JASO FD became the highest standard to judge engine oils. JASO FA standard has been discontinued since then and only JASO FB, JASO FC, and JASO FD remain.

JASO FA – It took into account factors like detergency, lubricity, exhaust smoke, initial torque, and exhaust system blocking.

JASO FB – It took into account the same factors as JASO FA but the requirements are higher than JASO FA.

JASO FC – JASO FC requires better detergency, exhaust system blocking, and exhaust smoke than JASO FB. The lubricity and torque requirements are either same or better in JASO FC.

JASO FD – JASO FD is very similar to JASO FC but this requires higher detergent.
