PRESENT STATUS OF JAPANESE MOTOR OILS AND EXTENSION OF OIL DRAIN INTERVALS

Recent trends in motor oils and drain interval extension in Japan are described. The present target proposed by Japanese automakers is an extension from 5000 km to 10,000 km which seems to be easily met by conventional SE oils. Recently, low ash-low phosphorus oils have predominated in the market in order to increase catalyst durability. It is not presently known whether or not an extended drain interval and such oils are compatible. In comparison with conventional SE oils, low ash-low phosphorus oils offer better valve train wear protection.
