The viscosity index measures an oil’s ability to resist changes in viscosity as temperature changes. Viscosity index improvers utilize polymer additives to help maintain oil viscosity over a wide range of temperatures. The more viscous the oil is, the more easily it coats and completely protects ...

The viscosity of an oil is measured by its resistance to flow. Check out engine oil grade descriptions and learn how motor oil viscosity works
The viscosity index (VI) and the base number (BN) of motor oils are the most important parameters to be measured in order to assess their performance and service time. Both parameters were simply obtained for virgin and recycled motor oil samples using multivariate calibration based on the FTIR...
An oil’s resistance to thinning in hotter temperatures is called the viscosity index. Although a higher second number is good, the oil also has to berobust, lasting for thousands of miles until the next oil change. Oil tends to lose viscosity from shear, which is the sliding motion in th...
