Advances in High Performance Synthetic Oil Technology

Unique performance advantages for polyalphaolefin (PAO) based synthetic engine oils have been documented since the mid-70's (1). The superior performance of these lubricants led the industry to develop improved mineral-based lubricants, including those produced by isomerization of waxes. Recently, an extensive research project was initiated to further enhance the performance advantages of PAO-based synthetic engine oils compared to highly refined mineral oils. A new generation of synthetic lubricant was developed delivering significantly improved performance in all areas. Although the development took place before the introduction of the API “SH” engine oil category, this new synthetic engine oil technology far exceeds API “SH” requirements as well as the API “CD” diesel performance specification. This paper discusses the standard and extended-length (U. S. and European) developmental engine tests, comparisons against premium mineral and synthetic oils and important motor sports performance.
