Uses and functions of Motor Oils

Motor oil or engine oil is a type of liquid industrial lubricant which is used for lubrication in various types of internal combustion engines like heavy and light automobile engines. These are also used in marine engines, agricultural engines, train engine, aeroplane engines etc. The key functions of motor oils or engine oils are to lubricate and clean the moving parts of machine or engine. Motor oil also prevents against corrosion and rust and makes cool the engines by carrying heat away from the sliding parts of the machine or engine. Generally motor oils are derived from petroleum oils. Motor oils provide a protective and stable film between moving parts of engine and reduce friction, wear, heat, noise, and makes cool the engine.

Now-a-days synthetic motor oils are also in vogue and gaining popularity on account of high performance. Synthetic motor oil is a blend of chemicals compounds and additives which provides similar performance as normal motor oil. Synthetic oil is made in the substitution of petroleum or industrial lubricants or usual petroleum based motor oils. The significant use of synthetic motor oils is shortage of petroleum and also the petroleum is too expensive.

Motor oils are used in different forms such as gear oils, greases, hydraulic oils, etc. Gear oils are specially used in gear or gear boxes of automobiles, trucks and other machinery. These oils are generally of higher viscosity. Other uses of engine oils are in propulsion of marine engines and generally such oils are termed as marine oils. Greases are other form of lubricants which are used for lubrication in moving parts or an engine or motor. Hydraulic oils or fluids are blend of petroleum based motor oils, water, and water based mixtures. These are used for lubrication in hydraulic machinery such as brakes, power steering etc.

Choosing the right motor oils is also a topic of discussion. The most important feature of motor oils or engine oils is their viscosity. Thicker oils have a higher viscosity and thinner oils have a lower viscosity. In engine motor oils should be used of right viscosity because of oils with too low viscosity can loose film strength between moving parts at high temperature and oils with too high viscosity may not pump to the proper parts at low temperatures. So while choosing motor oils or lubricants for your engine, keep it mind viscosity of oils should be according to your engine requirements. Thus, in brief, we see that motor oils play a major role in running an engine smoothly.
