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.
