Coulomb, in 1781, distinguished between static friction, the force required to start sliding, and kinetic friction, the force required to maintain it. He showed tha

Quantum Brownian Motion Revisitedengines with close tolerances between moving parts would not be possible without engine oils containing a tailored package of chemical additives. Progressive advances in additive technology not only allow today’s engines to operate efficiently, but also dramatically increase the engine’s useful life and reduce engine maintenance costs.

Quantitative Methods for Managementl of an oil for application over a wide temperature range. Pennsylvania grade oils (~ 100 VI) were the standard against which all others were measured. Hydrogenation and solvent extraction were developed to upgrade poorer quality crudes, but the refinery technology of the 1930s had a practical VI ceiling of about 110 to 115.

This book aims to bring together this chemical information and present it in a practical way. It is written by chemists who are authorities in the various specialisations within the lubricating industry, and is
