| Why Viscosity Index is Important |
|
| As the temperature of a gear oil increases, its ability to support a load decreases. This is due to the thinning effect that temperature has on the viscosity. The rate of change differs for each oil. The rate of change is expressed in an oil's viscosity index (VI) number. The higher the VI number, the lower the rate of change. If you have a hot gearbox that seems to have a low reliability rating, you might check to see if the oil has a suitable VI and is capable of holding up under the high temperatures. If the product's VI is less than 120, as shown on the product data sheet, then you might consider an alternative oil for the high-temperature, heavily loaded application.
