New engine design changes and ever increasing requirements make the design of gear oils challenging. Proper understanding of fundamental lubrication theory and formulation knowledge is necessary to develop new gear oils. This paper provides an overview on fundamentals of lubrication theory and functions of each additive. Also, key technical issues facing gear oils are discussed.
