: This paper discusses the development and application of the Cold Cranking Simulator (CCS) , a crucial laboratory tool used to measure the low-temperature cranking viscosity of engine oils. Significance
: Cold Cranking Simulator: A New Approach to the Viscometric Characterization of Engine Oils
The work described in this paper helped establish the standards for how motor oils are graded for winter use (the "W" in 5W-30, for example). It details how the simulator mimics the resistance an engine experiences when starting in extremely cold temperatures, ensuring that oil remains fluid enough to allow the engine to turn over.
