Introduction Lubricants, like all mechanical parts of equipment we use, undergo a process of degradation of their characteristics both physical and chemical properties under the influence of external constraints.
Lubricating oil is one of the most important factors affecting the life of the engine.
Any change in its composition or physicochemical properties during the service life can be classified as an aging process.
The latter includes the evolution of the physicochemical properties of oil in service with the characteristics of the new oil in the same category.
Indeed, our analysis we have found that several factors contributed to the degradation of the initial characteristics of the oil studied.
