Best Synthetic Oil

When we talk about engine oil, synthetic oil has been tested and proven to be the best option in terms of form, function, and protection for your vehicle. Synthetic oil is artificially made of chemical compounds with the aim to boost performance and purity. Not all synthetic oil are created or made equal, some are more potent than others, the question then is; what’s the best synthetic oil for your car?

Though synthetic oil is sometimes twice as expensive as conventional oil, synthetic oil would always come out on top when it comes to longevity and ability to handle extreme high temperatures without breaking down easily.

Let’s cut the chit-chat and get straight to the point, if what you are looking for is an excellent advanced synthetic oil from a reliable brand to keep your car’s engine running like new, Mobil 1 should be your Number 1 choice.


Mobil 1 is a reliable brand with excellent wear protection. Don’t just take our word for it, as far as volume of sales and proliferation in USA is concerned, Mobil 1 synthetic Motor Oil, is the leading brand, it is the most recognized synthetic Oil Brand in the World, Millions of Americans that rely on this product can’t be wrong. In the course of carrying out this research, I spoke to a number of industry experts and asked them to make their recommendation, Mobil 1 always came up in the top 3

On the other hand, if you are driving any of the luxury or performance cars that includes BMW, Audi, Range Rover, Mercedes-Benz, Porsche, and Ford, you’ll want to go for Castrol Edge 0W-40 A3/B4, there’s a reason it’s getting 5 solid stars rating on websites like Amazon, Walmart, etc.. I personally use Castrol (5W 20) on a Ford Edge 2011 Limited Edition and I can tell you that it runs very cool, in my opinion, I think it’s the best oil to use for higher performance vehicle.

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, and then a synthetic base stock is 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:

Compared to conventional motor oils, there are fewer impurities found in synthetic oils, which prevents deposits from forming in the engine and resist the formation of sludge.

  • 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 in cooler temperatures and in warmer conditions, higher viscosities can help improve engine performance. 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.
