Engine oil used in cars

Like blood functions in human body, engine oil does the same in car. Engine Oil is very important for smooth running of car as it forms a thin lubricating layer around parts of engine and protects them from getting damaged.. Oil also helps to keep the engine clean and cool. We include engine oil in our daily talks but many people still don’t have any idea about basics of engine oil i.e. its composition and types.

 

Composition of engine oil:

Engine is basically made up of two components: BASE OIL (80%) +  OIL ADDITIVES (20%). These  additives are called as performance additives           as they are used to increase the running performance of car. They play a role in keeping engine clean and also maintain viscosity of engine oil that allows the car to run at variety of temperatures. Base oil can be mineral oil, synthetic oil and a combination of two which is designated as semi synrhetic oil or partly synthetic oil.

 

Types of oil:

 

Mineral oil Semi synthetic oil Synthetic oil
Mineral oil consists of crude oil which is processed to remove impurities. It is the combination of mineral oil and synthetic oil It is the artificially synthesized oil made of different chemical constituents.
They are categorized as oil of thicker grades. Its performance is better than mineral oil but not like synthetic oil. They provide best performance but they are expensive.

 

Mineral engine oil Maruti Alto, WagonR, Swift petrol, Desire petrol, Hyundai eon, Santro, Hyundai i10, Grand i10, i20, ford figo, Honda cars,city petrol, Amaze petrol, Brio, Toyota etios
Semi synthetic engine oil Almost every car (except SUV cars, high semi synthetic engine oil performance cars)
Synthetic engine oil Maruti Swift diesel, Desire diesel, VW Polo, VW Vento,Ritz diesel,ford ecosport, Ertiga diesel, SUV cars, MPV diesel, Fiesta diesel, Skoda rapid, Luxury cars, cars with engine capacity >1.5 litre

 

Grading system of engine oils:

Society of Automotive Engineers (SAE) has developed a grading system for engine oil based on viscosity. Viscosity can be defined as fluid’s resistance to flow. Low viscosity fluids are thin while high viscosity fluids are thick. SAE grades the engine oil on the basis of viscosity at both hot and cold temperature. That’s why engine oil grades are designated by two numbers. Both single grade and multigrade engine oils are available. Single grade oil works only at onetemperature either at low or high while single multigrade oil will work  for both temperatures.

The first number indicates the viscosity at low temperature; W stands for “winter”; last number stands for viscosity at high temperature. The lower the first number , the thinner the oil which allow it to work even at low temperature efficiently. The higher the second number, the thicker the oil which allow it to work even at high temperature efficiently.

AUTO360 is using MOBIL AND MAK ENGINE OIL in all cars which enhance engine life and keep it clean. According to Customers feedback they find engine smoother as never before.
