They are the urgent problems to enact the specifications of mobile oil and gear oil. Concerning to these problems, the author describes the points to be cared. on performance tests of oils. In frigid locality the temperatures of lubricating oil in moving car are unexpectedly low. For this reason multi-grade oil is demanded. According to the progress of engines the pressures which act to connecting rod bearing, cam, or valve lifter are going to be higher. In this concern, the nature of extreme pressure of lubricating oil is needed, Barium in additives which is blended in these high grade lubricating oils may be the cause of sticking of exhaust valve. By the use of hypoid gear several problems must be investigated on gear oil. Then the author describes some problems on greases.
