Calculation Tools

RohMax has developed tools in order to enable the calculation of:

Blending Efficiency

• The percent by weight of a RohMax VII needed to reach a desired viscosity at 100 °C
• The viscosity at 100 °C of a blend containing a given amount of a RohMax VII

Viscosity Index

• The Viscosity Index of a formulation knowing its viscosity at 100 °C and 40 °C
• The viscosity at 100 ºC of a formulation knowing its VI and its viscosity at 40º

Base Oil Mixtures

• The viscosity of a mixture of oils with known viscosity
• The ratio of oils with known viscosity needed to achieve a desired viscosity

CCS Viscosity of Group I Base Oils

• The CCS viscosity of a base stock at a given temperature
• knowing its viscosity at 100 °C
