The Influence of Engine Oil Formulation on the Prevention of Valve Train Wear in Modern European Passenger Cars

The paper discusses the three principal wear modes that can occur in the valve train of passenger car engines, and the various factors that affect them. It shows how different lubricant components can influence wear and how, by careful selection of the additives and optimisation of their treatment level, premium passenger car motor oils of excellent anti-wear performance can be produced meeting the many conflicting requirements of the European car passenger market.
