OIL VISCOSITY NUMBER
SAE Viscosity numbers indicate only whether the all has a light or
heavy body, and do not consider other properties or qua lity.
The lower SAE numbers, such as SAE 5W and SAE 1 OW, indicate light
body oils recommended for use during cold weather to provide easy
starting and quick lubrication. Higher SAE numbers, such as SAE 20
and SAE 20W, represent heavy body oils for use during hot weather
and improved lubrication under high operating temperatures.
Some oils, termed "multi-viscosity oils," combine the easy
storling
characteristics of the lower SAE number oils and the worm weather
operating characteristics of the higher SAE number oils. These have
designations such as SAE 5W-20 and SAE 10W-30.
