Calculate the viscosity of a mixture of two oils

Mixing Oils

The calculations for mixing any two viscosities of oil to obtain a specific viscosity.

Note: You should only mix oils of the same brand and formulation

In the first module

Fill in

  • The viscosity of the first oil you want to mix
  • The viscosity of the second oil you want to mix
  • The percentage of the first oil you want to mix
  • The temperature of these two viscosities
Press “Calculate" to obtain the viscosity of this mixture at that given temperature and percentage.

Fill in the viscosities of two oils and the percent that you want to use of the first one, then click the button "Calculate"

To start over, click the button "Clear"

In the second module

Fill in:

  • The viscosity of the first oil you want to mix
  • The viscosity of the second oil you want to mix
  • Your desired final viscosity
  • The temperatures of these viscosities

Press “Calculate" to obtain the percentage of each oil that should be mixed to get that result.

Calculate the percentage of each oil you need to end up with a specific viscosity at a specific temperature

Fill in the viscosities of two oils and the viscosity desired, then click the button "Calculate"
