T1 - Automotive engine lubricants T2 - Fuels and lubricants handbook - Technology, properties, performance, and testing N2 - In 2003, ASTM Manual 37, Fuels and Lubricants Handbook: Technology, Properties, Performance and Testing, featured a chapter discussing automotive lubricants, including engine oils, automatic transmission fluids, manual transmission fluids, gear lubricants, and greases. This chapter, by Schwartz, Tung, and McMillan, surveyed all of these classes of lubricants, up to its publication in 2003. More recently, the period between 2003 and 2010 has been addressed as part of a book copublished by ASTM and SAE International (coeditors Simon Tung and George Totten), where Fox surveyed the development of engine oil specifications that emerged during those years. This chapter surveys the evolution of engine oil design and testing since 2002 and concludes with insights into future directions offered by recent tribological research. Our objective is to provide a reader new to the field with an understanding of the following: - Engine oil composition and formulation - North American engine oil specification development, and an outline of emergent European specifications - How emergent specifications and legislative requirements are linked to the introduction of new engine hardware - How tribological innovation can contribute to future enhancements in engine efficiency In parallel, we will provide several tables comparing groups of contemporaneous specifications.
