Q:

What does the acronym "SAE" mean on a package of motor oil?

A:

The acronym “SAE” stands for the "Society of Automotive Engineers." The Society of Automotive Engineers is the governing body that oversees the standards of engine oil grades.

For over 100 years, the Society of Automotive Engineers has been classifying engine oil based on its viscosity. Viscosity is a term that describes an oil's performance at a given temperature. Engine oil with a higher viscosity rating is thicker and performs better at high temperatures. Engine oil with a lower viscosity rating is thinner and is recommended for colder climates. Modern multigrade engine oil is rated for both low and high temperatures.

  • Q:

    What are the physical properties of motor oil?

    A:

    The physical properties of motor oil are viscosity, pour point, flash point, NOACK volatility, acidity and alkalinity. These properties vary based on the grade of motor oil and the petroleum base stock from which it is derived. They also reflect the presence of preservatives and other additives in oils that contain them.

  • Q:

    Does motor oil freeze?

    A:

    According to the Argonne National Laboratory, petroleum products do not freeze (crystallize), but their viscosity can become very high and adversely affect the instruments they run in, such as a motor. Viscosity is determined by what kind of motor oil or petroleum product is in question and by temperature.
