Friction Characteristics of Polyalkylene Glycol Based Engine Oil Formulations

Mineral based engine oil formulations have been used for several decades and served the industry well with incremental performance improvements including fuel economy. Over the past 20 years, engine oil derived fuel economy improved substantially through improvements in base oils and additive technology. However, further improvement appears challenging while maintaining durability and other performance requirements.
