ASTM D5293 Apparent Viscosity of Engine Oils and Base Stocks Between -5 and -35oC Using Cold Cranking Simulator
Lubricating oils are designed to protect engines from metal-on-metal wear. The viscosity of these oils normally increases as the temperature decreases. In cold weather, engine oil may become so viscous that it will not properly protect the engine. This test determines the viscosity of engine oil under very cold conditions, such as that seen in winter operations.
The test oil is applied to the rotor and stator of a cold cranking simulator and the system is cooled to the test temperature. The motor is started and the speed is recorded. This speed is compared to a standard calibrated oil to determine the apparent viscosity, which is reported in centipoises. Please provide the test temperature.
