Full Synthetic vs Synthetic Blend Oil (What’s the Difference?)

(Updated on April 17, 2020)

As you know, motor oil is the blood of every vehicle. But what you may not know is that there are different types of motor oils. Traditionally, people have used crude oil to lubricate the components of their engines. Crude oil is basically oil that has come right out of the ground and then refined for use in car engines. This convention oil has been used for many decades until automakers figured out how to create something called synthetic oils. Basically, synthetic oils are formulated through the use of artificially created chemical compounds. These compounds are made by breaking down petroleum molecules and then rebuilding them. The synthetic oil that is created has the ability to lubricate engine components far better than crude oil ever could.

Top 4 Differences

A lot of people just see the word “synthetic” and automatically assume that the oil is fully synthetic. There is not just one type of synthetic oil, though. There is full synthetic oil and then there is synthetic oil blend. Make sure you understand the difference between the two oils so that you know which is better for your vehicle. Below are the top 4 differences between full synthetic oil and synthetic oil blend.

  1. Ingredients – Full synthetic oil means it is completely manufactured with synthetic chemical compounds. Synthetic blend oil, on the other hand, is oil that contains a mixture of crude oil and synthetic oil compounds. This is done to give you the benefits of both oils.
  2. Cost – Full synthetic oil costs more than synthetic oil blend because there is a lot more scientific manufacturing that goes into it. However, synthetic oil blend is a cheaper alternative for those who still want the lubrication benefits of synthetic oil.
  3. Performance– Full synthetic oil is certainly the best performing oil because of all the additives and high-quality fluids used to make it. If you use synthetic oil blend, you will at least get a better performance out of it than if you were using crude oil.
  4. Brands – Full synthetic oil has multiple brands which each have different kinds of fluids and chemical additives that make them unique. It is up to the consumer to research these formulations to determine how much they will protect the components of their particular engine.

Remember that the formulations of synthetic oils are different, even when it comes to synthetic oil blends. After oil, synthetic oil blends can still have different additives in them too. Certain additives perform a specific duty in your engine that you may want to have done. For example, let’s say you want your synthetic oil to do a better cleaning job in your engine. What you could do is choose a synthetic oil that has an additive in it specifically for cleanliness. But don’t use too much of the additive because it could reduce the wear production that you’re supposed to get as well. This is something you don’t want to happen if you’re normally driving under tough conditions, such as snowy or rainy weather.

Overall, full synthetic oil is best for people who don’t mind spending the extra money on it. This will give you the best performance possible for your engine. Just make sure the synthetic oil brand that you choose has a premium base stock to it. There are some companies that will try to sell cheaper versions of full synthetic oil, but with lower quality base stocks. If you are unsure about which one to choose, talk with a professional mechanic in your area about which is best for your car. Also, check the owner’s manual of your car because it might recommend the exact synthetic oil to use.
