Oil with a viscosity that does not change much between the temperatures of 40°C and 100°C has a higher VI than an oil with a relatively higher change in viscosity. The Viscosity Index Test (ASTM D ...

This is a reduction of more than 75 percent. Also note that the magnesium count for the SN+ oil also increased over the SN version. The differences in viscosity do not affect these additive packages.

Important Factors When choosing the right viscosity oil for your equipment there are some important factors to consider: shear stress conditions, Viscosity Index (VI), and component temperature are ...

Synthetic motor oil offers many advantages over conventional engine oil. Synthetics resist chemical degradation far better than traditional oils, and they typically have a higher viscosity index ...

Ultimately, there’s a lot to consider when it comes to your car’s oil, including the type and viscosity, how often you should have oil changes done, and even how to check the oil properly.
