Scope
This standard specifies the multi-cylinder engine sequence IIID test method for evaluating the performance of automotive engine oils. Note: This test method is designed for high-temperature environments and highway driving operations. It describes the engine test procedures for evaluating the high-temperature thickening characteristics of vehicle engine oil, sludge and paint deposition, and engine wear performance. The evaluation of viscosity increase in this test , indicating the tendency of engine oil to oxidize and thicken, which will lead to a lack of lubricant
