Engine oil function

Chemists play a role in the addition of additives to improve the properties of motor oil. As steel and aluminum parts move closely against one another, friction between the two parts creates heat and wears away the metallic surfaces. This will lead to decreased efficiency, increased fuel consumption, decreased power output, and eventually engine failure. Engine additives are devised to combat these consequences. A list of engine additives follows however, rather than discussing each one in depth, we will discuss only some of the more important ones  

Another function of the motor oil is to coat the parts to minimize exposure to oxygen. Corrosion inhibitors within the oil assist in this function. Sludge buildup is a result of degradation of the oil after exposure to the heat and extreme pressure conditions of the engine. Many motor oils have detergents and dispersants to combat this prob-
