Summary:

Japan Automobile Standards Organization (JASO) Engine Oil Sub-committee have been working on the unification of the engine oil evaluation test procedures in Japan. The Engine Oil Sub-committee participated in the recent activity of the worldwide engine oil standardization of SAE and ISO. As one of the chain of activities, JASO tests M328, M331, and M333 (valve train wear, detergency and high temperature oxidation respectively) were conducted on the REOs of ASTM and CEC to find the correlation.The detergency tests (varnish and sludge) showed good correlation with the ASTM REOs. CEC good and poor reference oils seemed to give good results in JASO valve train wear test, while ASTM reference oils unexpectedly gave opposite results in Japanese valve train wear tests
