Clearly, a test method indicating gelation during slow cooling of the oil over a wide low-temperature range was required. Determining the viscosity and gelation point at low temperatures helps minimize flow problems.Īn oil’s pumpability behavior at low temperature is of particular interest since a catastrophic number of air-binding failures occurred in 1980 due to gelation, with numerous car engines damaged in the winter because of bad engine oil. s is critical for pumping, depending on the engine manufacturer.Flow-limited behavior is associated with the oil’s viscosity and air-binding behavior is associated with gelation. Standardized quality control tests ensure the proper flow and pumpability of the test medium and identify flow problems, which, in oil, can be caused by flow-limited and/or air-binding behavior. An engine requires a sufficient quantity of lubricant to prevent engine damage immediately or eventually after cold temperature starting. Moreover, cold start behavior in car motors or generators using an oil can be simulated. Measuring the viscosity of oils at low temperatures can help guarantee the proper operation of mechanical devices.
