A lubricant or process fluid composition having excellent low temperature properties comprises a capped estolide ester, a polyalphaolefin, a synthetic ester and/or polyalkylene glycol, and a pour point depressant. The combination of the three base oils plus the pour point depressant produces a synergistic composition that may have a pour point less than -15° C., preferably less than -35° C., while also having more than 50 percent by weight renewable carbons and being economical and effective in a wide variety of applications. |
