Types Of Synthetic oil

It is important to note that various companies and brands have put in major research and development in the formulation of their oil. While various formulas achieve a given outcome, there are basically two types of synthetic oil: Full Synthetic Oil and Synthetic Blend. Here’s what you need to know about both:

Full Synthetic Oil

Full synthetic oils are made from crude oil or by-products through a chemical process rather than the distillation process used for conventional oil. They use a synthetic base stock mixed with a variety of additives that boost the performance of the oil.

While synthetic oil may offer a higher level of protection than synthetic blends or conventional oil, not all synthetics are equal.

Synthetic Blend

Synthetic Blend is a mix of conventional motor oils and synthetic base stocks. As a result of added synthetic base stock in Synthetic Blends, they provide better performance and protection when compared to your conventional oil.

Benefits Of Synthetic Oil

There are a number of benefits in using synthetic oil. Regardless of their slight differences, the good news is there is always a product for you; depending on your focus area, car type or location. Just to list a few, here are some benefits of synthetic oil:

  • Longer Engine Life and reduced oil sludge problems:

Synthetic oils contain fewer impurities compared to conventional motor oils and can better resist the formation of sludge thereby preventing deposits from forming in your engine.

  • Better low- and high-temperature performance:

Synthetic oils are engineered to flow quickly even at low temperatures, they start protecting your engine right after you start your car. Furthermore, in higher temperatures synthetic oils do not easily break down or evaporate.

  • Improved fuel efficiency and Lower oil consumption under high-speed conditions.
  • Extended drain intervals, with the environmental benefit of less used oil waste generated.
  • Increased horsepower and torque due to less initial drag on engine.

What To Consider When Picking The Best Synthetic Oil

various brands and products contain very different types and combinations of base oils and additives. Though there might be some differences in the formulation of these oils, it is almost impossible to tell the difference in terms of performance.

To determine which synthetic oil is best for you, it is best to refer to your owner’s manual; it gives a detailed breakdown on what type of oil is needed for the car.

When considering the best oil to use, a few things such as; viscosity, lubrication properties, fuel Economy, better wear protection, durability and sometimes a combination of all or just the Best price as compared to delivery should be put into consideration?

  • Viscosity: Lower viscosities are better adapted to cold weather use, while higher viscosities can help improve engine performance in warmer conditions. Various oils usually have numbers printed on them; an example would be the “5W-30”. The two numbers refer to the oil’s viscosity properties during a cold start and at high operating temperatures.
  • Lubrication Properties – lubrication and reduction in the friction between a number of critical engine components is singlehandedly one of the most important role of an engine oil. The higher its properties in this area, the better it is for the engine.
  • Fuel Economy: The less friction the oil puts on the internal pathways of the motor, the more efficient the car becomes in fuel economy; due to the fact that the engine has to work less in the oil circulation process.
