At Blackstone we report the high-temp viscosity, which is generally the temperature the engine is at while it’s running and the temperature at which the oil spends most of its time. The viscosity of an oil could be reported at any temperature, but to standardize things, most laboratories report either a low temp (100F or 40C) or a high temp viscosity (212F or 100C) and stick with either Fahrenheit or Celsius. To be more specific, it is the thickness of oil at a given temperature. Commonly, though, we think of it as an oil’s thickness. Technically, viscosity is defined as resistance to flow. We tend to choose an oil with a viscosity that we believe is correct for our particular engine, but would another viscosity improve or reduce the life of the engine? Can we pick and choose a viscosity outside the manufacturer’s recommendations? Most of us have only a vague understanding of viscosity.
