CCS apparent viscosity of automotive engine oils correlates with low
temperature engine cranking. CCS apparent viscosity is not suitable
for predicting low temperature flow to the engine oil pump and oil
distribution system. Engine cranking data were measured by the Coordinating Research CouncilThe measurement of the cranking viscosity of base stocks is typically done to determine their suitability
for use in engine oil formulations. A significant number of the
calibration oils for this method are base stocks that could be used in engine oil formulations.
Cold Cranking Simulator (CCS) viscosity apparatus conforms to the SAE J300 and ASTM D5293 Standard Test Method for Apparent Viscosity of Engine Oils and Base Stocks Between –5 and –35°C Using Cold-Cranking Simulator, which used for determining apparent viscosity of engine oils and base stocks by cold cranking simulator (CCS) at temperatures between –5 and –35°C at shear stresses of approximately 50 000 to 100 000 Pa and shear rates of approximately 105 to 104 s–1 for viscosities of approximately 900 to 25 000 mPa•s. The range of an instrument is dependent on the instrument model and software version installed.Apparent Cranking Viscosity results by this method are related to engine-cranking characteristics of engine oils.
