A lot of people are asking the question, “What is better full synthetic oil or a synthetic blend?” The answer to this question will be different for every person. It all depends on what type of car you have. If your car is made primarily with plastic components, then full synthetic oil may be best because it resists oxidation and corrosion better than synthetics blends do.

However, if you have an engine that needs more lubrication due to its size and power levels, a synthetic blend would be best because it has higher viscosity ratings than full synthetic oils. However, always remember that viscosity is not the only determining factor when choosing an oil.

Full Synthetic Oil

This is the premium wine in the world of engines. It’s the one everyone wants but not all can afford it. Synthetic Oils are artificial oils that have been formulated in the laboratory for enhanced performance. The formulation starts with a petroleum base which later is mixed with additives giving it unique advantages over conventional ones such as enhanced purity, protection, tolerance, and versatility.

Synthetic Blend Oil

Finally, it’s time to talk about Synthetic Blend Oil. A synthetic blend is obtained by mixing conventional and synthetic bases. Thus the oil obtained has the qualities of a Full synthetic one but comes with a much affordable price tag. Thus you get better stability and performance for a fraction of the price.

Main Difference

Recent studies show that about 45% of vehicle owners have opted for synthetic oils of some sort. But there is a huge confusion among them regarding the Full Synthetic Oil and Synthetic Blend of oil.

Many have been using conventional oils for decades and find it extremely uncomfortable to switch to all synthetic all of a sudden. Below is a brief discussion that will help you find a light among the haze.


Full synthetic is a clear winner in terms of composition and it’s pretty obvious after all Synthetic blends are downgraded versions of the full synthetic ones when it comes to quality.

The prior one is formulated using an excellent petroleum base and useful additives, whereas the latter one is a mixture of a synthetic base with the same old crude oil.

Oil Change Interval

This is a major factor and influences buying decisions to a lot extent. While full-synthetic oils have an impressive life span of 7,500 to 10,000 miles depending on models and usage, Synthetic blends don’t shy behind offering 3,000 to 5,000 miles before oil change. To know more about the it checks here Synthetic Oil Change.

Vehicle Life

Better oil results in an increased life span for your ride. Full synthetic oils have a clear advantage here as it comes with better composition offering improved shear and chemical stability, superior viscosity performance in adverse temperatures, better viscosity index, optimum resistance to oxidation, oil sludge, and thermal breakdowns. Synthetic blends having impurities of crude oil fails to deliver the same.


Ultimate it all comes down to the price cause it’s the main motive behind offering synthetic blends besides full synthetic ones. Synthetic blends can cut your cost by ten to 30 percent depending on the brand. Unless you are looking for top-tier performance and protection, the synthetic blends will offer a noticeable upgrade over the conventional oil without breaking the bank.

Can You Mix Synthetic Oil With Synthetic Blend

Mixing oils is a common buzz among car owners and it’s no exception in the case of synthetic ones. While you can mix synthetic oils with a synthetic blend, we highly recommend not to do it.

The reason is simple. Synthetic blends have crude oil in them and with that comes all the negative factors of crude oil. So by mixing oils, you are letting the impurities and unstable components of crude mess up the formation of pure synthetic oil. This makes the additive in synthetic oils useless.

Though this procedure won’t cause any major harm to the public, it’s just a waste of money. Thus unless you are forced to do so, it is recommended not to mix any two oils of a different kind. In short, it’s safe to go by the manufacturer’s manual while opting for an oil.


Full synthetic oil is best when it comes to protection and performance. The superior quality of full-synthetic oils, in fact, makes them perfect for both older as well as new cars. On the contrary, Synthetic blends are good enough for entry-level vehicles which have a relatively low demand for their engine parts.

If you own an old car with higher lubrication needs, then it would be best to go for full synthetic oil. But if you own a new and powerful car, a Synthetic blend will suit your requirements just fine.

Frequently Asked Questions (FAQ)

It depends on your individual needs and preferences. If you’re looking for the best possible protection and performance for your engine, full synthetic oil is a good choice. However, if you’re on a budget, synthetic blend oil may be a better option for you.
