Oil Cooler and Thermostatic Sandwich Plate 101 – What and Why

Heat is an engine killer. While most drivers will never experience excessively high oil temperatures, those who race or tow heavy loads can experience over-heated oil. Over-heated oil is bad for three reasons:

1. As oil is heated above 200 degrees Fahrenheit (and stays at these sustained temps) breakdown of that oil is accelerated.
2. As oil is heated above 200, it’s a less effective engine lubricant.
3. In addition to lubricating the engine, oil also helps to cool your motor. If the oil is too hot, it’s less effective at cooling the engine because it can’t absorb as much heat.

Enter the oil cooler, which keeps engine oil at an acceptable temperature, helps cool the engine, extends oil life, and reduces engine wear.
