Motor oil, also known as engine oil or engine lubricant, plays a crucial role in the smooth operation and longevity of internal combustion engines. It is a complex substance composed primarily of base oils, which are then fortified with a variety of additives to enhance its performance and protective capabilities. The composition of motor oil typically includes base oils that can be derived from petroleum crude oil or synthetic sources. These base oils provide the essential lubrication that reduces friction and wear between moving parts within the engine. However, the effectiveness of motor oil goes beyond mere lubrication.
