We already know by now that motor oil is primarily a lubricating oil used in automobiles using internal combustion engine. In an internal combustion engine, there are many moving parts which are made of high-quality metal. Since they are metallic in nature the operational friction and high temperatures caused due to the burning of fuel creates immense stress on the component parts. The high operational temperatures coupled with high pressures in an internal combustion engine makes things even harsher.
This not only wears the parts but also results in less efficiency for the entire system as lots of energy is being wasted due to friction. Motor oil engulfs all the moving and operation critical parts of the engine. It creates a protective covering on the parts so when they come in contact with each other the friction is reduced to safe levels and the components are protected.
This oil also transfers heat in form of convection. However smaller engines prefer adapting total loss oiling as a preferred option. In other engines, the oil may be recirculated using an oil pump hence cooling it down again and again.
We all know that in an internal combustion engine there are lots of moving parts which come in contact with each other. This constant contact with each other causes debris to be formed. This debris can then come in contact with other engine parts and cause serious damage. To prevent this the oil is passed through an oil filter which takes care of this issue and hence protects the engine even further.
