Excerpt

The pursuit of improved fuel economy and lower CO2 emissions is leading to the viscosity of engine oils continuing to fall, with each new formulation introducing the further complication of a different set of additives. Research at Federal-Mogul shows that while the resulting reduced friction and parasitic losses can significantly improve emissions and fuel economy, changes in operating conditions lead to significant differences in performance. New test techniques have been developed to investigate these relationships and to guide the choice of coating technology. …
