Different types of Synthetic Motor Oil

The Synthetic Motor Oil made after going through much manufacturing process. Company to company, they have different process to follow, which includes getting raw ingredients from underground natural resource. And refined them from crude oil to get the Synthetic Motor Oil after adding extra chemicals which needed for today’s advance engines, which are high powered and uses high torque and greater horsepower on engine.

The total re-engineering of crude oil to Synthetic Motor oil includes removing of heat and other heavy metal components which protects vehicle engine from toxic build ups of sludge and enhances high-lubrication esters to critical components of engine. It also protects engine from atmospheric conditions like in winter, engine needs to be more lubricated to start.

Synthetic Motor Oils are rated on the “Viscosity” (it is industry metric which decide oil type based on temperature variation it processed). The different viscosity of Synthetic Motor oil is 5, 10, 15, 20, 30, 40 and 50. The first 4 viscosity are denoted by ‘W’ suffix to indicate that it is designed to use in Winter/cold condition, by The Society of Automotive Engineers.

For summer/hot conditions, oils are graded at 20 viscosity. Below is guide to choose the Synthetic Motor Oil from wide range of variety.

How to Choose Best Synthetic Motor Oil?

To choose the Synthetic Motor oil, you need to consider below mentioned important topics;

Viscosity: – As mentioned above, all Synthetic Motor oil are differentiated on the industry standard of Viscosity. Lower the Viscosity (i.e 5W) are considered good for winter conditions, while higher viscosity standard helps engine in Warm/Summer condition.

Lubrication properties: – Reducing the Frictional and increase the lubrication of moving parts of engine is the main goal of Synthetic Motor Oil. Do consider lubrication properties and friction properties of Engine oil.

Fuel Economy: – As less as possible friction put by Synthetic Motor Oil on internal pathways of engine, greater the mileage of vehicle. Friction properties lesser the work of oil to circulate in engine.

As mentioned above, a good Synthetic Motor Oil can improve your fuel economy by 5%.

Special Additives: – The more carefully blend the special Additives in oil, the more deposit and sludge in engine as it stops the oil leaks.

What is the Best Synthetic Motor Oil?

A well research guide which considered Viscosity of oil, special Additives in oil, Lubrication and frictional properties of oil and fuel economy capacity, we have short listed top 5 Synthetic Motor Oil which can improve health of your Engine Oil.
