2. What is the difference between a synthetic lubricant and a mineral lubricant?

        Is onebetter than the other?A lubricant is categorized as synthetic or mineral depending on the method used to obtain the lubricant's main component: the base oil.When the base oil is obtained through the conventional refining of petroleum, it is considered mineral oil. When it is obtained through more complex processes (e.g.chemical synthesis), the lubricant is considered synthetic.The origin of the base oil is not indicative of lubricant quality. In other words, a lubricantcannot be considered better or worse than the others for being mineral or synthetic.The quality of the compounds is determined by laboratory and engine tests that the lubricantundergoes during the design phase.
