The following results obtained in the test of the engine oil, which contained some friction-proof agents.1 The engine performance was constant, but lowerd the temperature of oils by about 7-8° C when Moly Slip was added.2 Fuel consumption was unchangable.3 It was supposed that the oil consumption depended mainly upon the number of oil rings are not upon the friction-proof agent.4 Any effect of the friction-proof agent was not recognized in the results of both physical and chemical analyses, such as the carbon residue, ash content, total base number, and the n-pentane insolube.5 The effect of friction-proof agent was recognized in boundary lubricant, for example, in case of four ball test.From the above result, little effect of the friction-proof agent was recognized under the moving condition of 1/2 load and 1300rpm. Reverse result, however, might have been obtained under the moving condition of over-load and max, revolution.
