Blending efficiency

Calculation of the % by weight of an Evonik Oil Additives VII needed to reach a desired viscosity at 100 °C.

  1. Enter the base oil viscosity at 100 ºC in mm²/s
  2. Enter the targeted formulated oil viscosity at 100 ºC in mm²/s
  3. Select the VII from the drop-down list
  4. Click on the "Calculate" button

 

To reset the calculation, click on the "New values" button.

 

(KV Base, KV Blend, VII) > %VII
Base Oil: KV100 mm²/s
Blend: KV100 mm²/s
VII
Result: VII %
Result: Base %
 

 

(KV Base, VII, %VII) > KV Blend
Base Oil: KV100 cSt
VII %
 
Result: KV 100 Blend cSt
 

 

Please note: This calculation is only valid for Grp I oils. For Grp II/III oils the calculation results will deviate from actual values.
