Engine oil, an important fluid in your vehicle. Without which your car or bike wont function as expected. Know more about the engine oil

What will the oil do?: it creates a thin, lubricating layer between metal surfaces, which stops them from grinding against each other and becoming worn or damaged. Oil also prevents corrosion, cools the engine and helps keep the engine clean and protected.

What is it made of: Oil typically consists of about 80% base oil and 20% performance additives. The performance additives include anti-wear additives, antioxidants, dispersants and detergents that keep the engine clean, and viscosity index improvers that ensure the oil maintains an optimum viscosity throughout the engine’s operating temperature range. The base oil carries these additives to where they are needed, and provides vital cooling to engine components, by drawing away heat. Base oils can be either mineral or synthetic, and engine oils can contain all mineral base oil, all synthetic base oil, or a mixture of the two. Engine oils containing a mixture are typically described as part-synthetic.

Types of engine oil: Synthetic oils, Part Synthetic oils, and Mineral oils

Synthetic oils are chemically synthesized to meet the exacting demands of modern engines. This makes them more expensive to produce, but because they are tailor-made they provide the best performance, protection and fuel economy. They also remain stable at very high temperatures and fluid at very low temperatures.

Part-synthetic oils are a blend of mineral and synthetic oils. They provide better performance, protection and fuel economy than mineral oils, but not as good as a full synthetic.

Mineral oils are made from naturally occurring crude oil which is refined and processed to remove waxes and impurities and tend to be found in the thicker grades of engine oils.


The viscosity of oil changes with temperature, therefore multigrade oils were developed to provide protection across a range of operating temperatures.

The SAE (Society of Automotive Engineers) scale shows the viscosity of oil at both hot and cold temperatures. That’s why the viscosity grade on the oil bottle is made up of two numbers.

Which to use: Always prefer to use a branded engine oil like Valvoline, Castrol, Mobil, Shell and their competitors in market. Never compromise with the engine oil. One more easy way is to contact Doers, we will do the rest for your car or bike.
