Motor oil, engine oil, or engine lubricant is any of various substances (comprising oil enhanced with additives, for example, in many cases, extreme pressure additives) that are used for lubrication of internal combustion engines. The main function of motor oil is to reduce wear on moving parts; it also cleans, inhibits corrosion, improves sealing, and cools the engine by carrying heat away from moving parts.1 Motor oils are derived from petroleum-based and non-petroleum-synthesized chemical compounds.
Motor oils today are mainly blended by using base oils composed of hydrocarbons, polyalphaolefins (PAO), and polyinternal olefins2 (PIO), thus organic compounds consisting entirely of carbon and hydrogen.The base oils of some high-performance motor oils contain up to 20% by weight of esters.3Źródło: https://en.wikipedia.org/wiki/Motor_oil
However, there are also cases in which the replacement is very fast operation due to the lower quality of the product and must again replace the part.
In this case, the preferred embodiment may be used to purchase a car parts.Admittedly, car parts, which have already been used can be a bit tired, but they tend to be several times cheaper than new equipment.
