Base oil, electric oil or hydraulic fluid formulation, method for preparing a base oil formulation, use of a fischer-tropsch derived diesel, and method for improving cold flow properties and / or reducing kinematic viscosity of a base oil formulation
Base oil, electric oil or hydraulic fluid formulation, method for preparing a base oil formulation, use of a fischer-tropsch derived diesel, and method for improving cold flow properties and / or reducing kinematic viscosity of a base oil formulation
Base oil formulation containing (i) a Fischer-Tropsch derived light base oil and (ii) a Fischer-Tropsch derived gas oil. The formulation can be prepared by back-blending a Fischer-Tropsch derived light base oil with a Fischer-Tropsch derived gas oil, for instance derived from the same Fischer-Tropsch synthesis. Also provided is the use of a Fischer-Tropsch derived gas oil in a base oil formulation containing a Fischer-Tropsch derived light base oil, for the purpose of improving the cold flow properties of the formulation while maintaining its flash point above a desired target value, and/or for the purpose of reducing the concentration of a cold flow additive in the formulation, preferably with less of a reduction in the flash point of the formulation than theory would have predicted to occur due to the incorporation of the Fischer-Tropsch derived gas oil.
