Interpretive Summary:

Technical Abstract: One obvious approach to increase efficiencies in many lubricated systems such as ICE and gearbox is the reduction in viscosity of oil lubricant. Indeed, ultra-low viscosity engine oils are now commercially available. One approach to the development of ultra-low viscosity lubricants without compromising reliability and durability of the lubricated system is the use of composite base-fluid consisting of many constituents with optimized rheological and surface properties. This paper presents evaluation of rheological properties, friction and wear performance attributes of PAO-2 and bio-based ester composite fluids with viscosity about 3 cSt at 100°C. The composite base-fluid showed substantial wear reduction and noticeable reduction in friction compared to PAO-2 and bio-based ester. Additions of antiwear and friction modifier additives further enhanced the tribological performance of composite base fluids under different contact conditions.
