WebThe first unit is the centipoise (cP). It is used to report the absolute viscosity of an motor oil at colder temperatures. This number indicates the ease with which the oil can be moved. The other unit is the Centistoke (cSt) which is used to report the kinematic viscosity of motor oil at high temperatures. The number reflects the time required ... WebIn other words, a SAE 30 motor oil is the same viscosity as a 10w-30 or 5W-30 at 210° (100° C). The difference is when the viscosity is tested at a much colder temperature. For example, a 5W-30 motor oil performs like a SAE 5 motor oil would perform at the cold temperature specified, but still has the SAE 30 viscosity at 210° F (100° C ...

WebTo recap, a lower oil viscosity number indicates a thinner oil that will flow faster, while higher oil viscosity number indicates a thicker oil which often works better in extreme applications. For engines that do not have a …

WebThe number before “W” is the low temperature oil viscosity. It’s measured at -17.8°C (0°F) and simulates the vehicle startup conditions in winter.
