A method of retaining or decreasing the pour point of an estolide base oil by increasing the EN of the estolide base oil, comprising selecting an estolide base oil having an initial EN and an initial pour point and removing at least a portion of the estolide base oil, said portion exhibiting an EN that is less than the initial EN of the estolide base oil. The resulting estolide base oil exhibits an EN that is greater than the initial EN of the estolide base oil, and a pour point that is equal to or lower than the initial pour point of the estolide base oil. |
