A Review of Engine Oil Oxidation Bench Tests and Their Application in the Screening of New Antioxidant Systems for Low Phosphorus Engine Oils—V. GATTO, W. MOEHLE, E SCHNELLER, T. BURRIS, T. COBB, AND M. FEATHERSTONE

This book represents the work of several authors at the 1st Symposium organized by D02 to focus
on automotive lubricant testing and advanced additive development. This symposium was held at
Lake Buena Vista, Florida, in conjunction with the meeting in December 2006 of the ASTM D02
sub-committee “Fuels & Lubricants”.

In order to help automotive industry meet lower emission standards, higher fuel economy goals,
and loger drain intervals associated with a minimization of any adverse effects of lubricants to
the environment, the petroleum industries and the additive suppliers are developing low SAPS
sulfated ash, phosphorus and sulfur and high tribological performance lubricants to meet these
challenges. New developments in powertrain system design and advanced additive formulation
are essential in addressing these problems. This ASTM symposium has provided an outstanding
forum to discuss how OEMs and lubricant companies are solving real engineering problems to
increase fuel economy and meet emissions legislation together. This symposium publication is
focused on both the chemical and tribological aspects of the functional performance of automotive
lubricant and testing. In this symposium, recent advances in additive and base oil chemistry
and function have been covered in details; product formulation for engine performance and the
link between additive chemistry and emissions have been discussed. Tribological performance
issues such as fuel economy retention, wear protection and friction reduction as well as their
retention over drain, engine durability, and future challenges, including advanced powertrain
developments, new lubricant test methods outside of the application, lubricant formulations, and
correlation between lubricant formulation and engine performance are the key subjects
