Conventional polyalkylene glycols (PAGs) that are derived from the polymerization of ethylene oxide and/or propylene oxide provide many performance benefits such as excellent friction control, good low temperature properties, high viscosity indices and excellent deposit control. One limitation is their poor miscibility in hydrocarbon oils. A new range of oil‐soluble PAG base oils has been developed using butylene oxide as one of the precursors, and these provide superior miscibility in hydrocarbon base stocks. The new base oils offer many of the traditional advantages of PAGs such as high viscosity indices, good low temperature properties and good traction behaviour. In addition, they can be used as a co‐base oil or additive in hydrocarbon base stocks to improve deposit control and provide good film‐forming behaviour. Examples of their structure property relationships will be discussed and also aspects of how this technology may enable application expansion of PAGs in the future.
