- (1) Lubricating Oils are those products of petroleum that are commonly used in lubricating or oiling engines, and any devices or substitutes for such products of petroleum.
- (2) Viscosity means a measure of the time for a fixed volume of lubricating oil to flow by gravity through thecapillary viscometer under an accurately reproducible head and at a closely controlled temperature. The kinematic viscosity is then calculated from the measured flow time and the calibration constant of the viscometer.
- (3) Multiviscosity refers to and means numbered lubricating oils whose 0° F viscosity falls within the prescribed range of one of the SAE W weight classifications and whose 210° F viscosity falls within the prescribed range of one of the higher non-W weight SAE classifications.
- (4) SAE refers to and means Society of Automotive Engineers.
