Abstract
Abstract Contaminants in engine oil alter its structure in different ways, depending on their nature, leading to the degradation of the lubricant and, if it is not replaced in time, even to loss of engine performance and its failure. Consequently, both for environmental reasons and from an economic point of view, it is important to be aware of the danger that these substances may present. This paper offers an investigation of the engine oil contaminants in general, emphasizing the most dangerous ones. It also includes the causes that contribute to their appearance, the types of contaminants, the way they act, the processes that result from contamination and the impact they have on engine components.
