Full Answer

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.
