Synthetic blend vs full synthetic oil

Synthetic blend vs full synthetic oil, If you’re anything like us, you’re undoubtedly wondering what their differences are. Oil is necessary for every car with a combustion engine to keep the internal functioning smoothly, cool, and free of corrosion. However, not every oil requirement is the same. While some vehicles can operate with regular oil, many others need a more refined lubricant. Products made of synthetic oil can help with that.

Though they both derive from the same underlying crude oil as traditional oil does, full synthetic and synthetic blend oils differ significantly from one another. Each is refined to a different degree, and the compounds that each grade contains might vary greatly, providing good, better, and greatest degrees of protection. Thus, in this article, we’ll be discussing “synthetic blend vs full synthetic oil”.

synthetic blend vs full synthetic

So, let’s dive in!


Synthetic blend vs full synthetic oil

The followings are the difference between a synthetic blend and a full synthetic oil, their differences based on;

How they are made

Synthetic blend oil

Traditional oil (mineral oil) and synthetic motor oil are used as basic oils to create synthetic blend oil. The mixture is then supplemented with various additives, conventional and synthetic mineral oils, and modifiers.

Brand to brand can differ in the proportion of conventional motor oil to synthetic base stock oils in a synthetic blend. As a result, some semi-synthetic oil blends may function more effectively than others.

Full synthetic oil

Full synthetic motor oil is produced exclusively in factories. It is made up of base oil that has been entirely refined from crude oil or petroleum. The best molecules are preserved while still producing this base oil by altering the hydrocarbon atoms’ basic structure.

Because synthetic oil is produced chemically in a lab, it can be highly expensive. However, it is of the highest quality and provides excellent performance.

Based on price

Synthetic mix oil tends to be less expensive than synthetic oil because it is much simpler to obtain. As a result, maintenance is more affordable and environmentally friendly.

Full synthetic oil is 30% more expensive than conventional synthetic mix oil because of the intricate production process. Additionally, maintenance costs might be high, especially when you consider how much extra you’re paying for each quart of motor oil.

Oil Change Intervals

Synthetic blend oil

An average of 6,000 miles can be covered by an oil change with the synthetic blend. Although it doesn’t function as well as fully synthetic motor oil, it still outperforms mineral oil.

Some kinds of synthetic blend motor oil may even promise 7,500 miles between changes. This is because of how much conventional base oil they use compared to synthetic base oil.

Full synthetic oil

Synthetic oil performs far better than any other motor oil because of its highly refined nature and the addition of synthetic chemical ingredients.

On the low end, a synthetic oil change interval can run 5,000 miles without a change. And before it needs to be changed, its best performance can go anywhere between 10,000 and 15,000 miles.

Differences based on their differences

Synthetic blend

  • It costs far less than synthetic engine oil.
  • Because it is less expensive, it is sustainable to make regular oil changes and has greater fuel efficiency.
  • Because synthetic base oil is added, it’s perfect for heavy-duty use and is frequently suggested for light vehicles and SUVs.
  • Compared to traditional oil manufactured from crude oil, it offers superior defense against sludge, friction, and engine wear.
  • In contrast to regular oil, it is capable of withstanding high temperatures without degrading.

Full synthetic

  • In comparison to standard mineral oils or synthetic oil blends, it provides longer oil change intervals.
  • It has good fuel efficiency because you don’t need to change it frequently, which lowers overall oil usage.
  • Fully synthetic oil is more predictable than synthetic mix oil because it only contains synthetic additive components.
  • It guards against the buildup of engine sludge and moisture damage to engine components.
  • Its improved engine efficiency and lower friction preserve the engine parts in good working order for a very long time.

Benefits of both synthetic blend and full synthetic

  • Preserving engine cleanliness to remove contaminants.
  • Preventing the buildup of sludge and defending against engine wear.
  • Avoiding friction by lubricating and protecting engine components.
  • Preventing corrosion and water damage to engine components.
  • Maintaining the engine’s temperature and keeping it cool.

Fully synthetic and synthetic blend motor oils have a number of additional uses in addition to these. Some are more suitable Than ordinary oil for specific uses because of their special characteristics.

Which one is best

Full synthetic and conventional oils are both included in synthetic blend oil. As a result, it won’t provide as excellent protection as a fully synthetic option.

Your car will function better at low temperatures if you use synthetic oil. Additionally, it has superior heat resistance and thermal stability and can aid with your car’s oil shear stability.

The performance of oil burn will also be improved by 100% synthetic. Therefore, it is considerably less likely that full synthetic oil will seep into your combustion chamber. Additionally, 100% synthetic oil has a lower propensity to evaporate or change suddenly.

Full synthetic oil has base constituents that are stronger. Consequently, it will perform better than synthetic blend oil. You won’t need to change your oil as frequently as you would with synthetic blend oil because full synthetic tends to break down more slowly. Depending on your vehicle, you need to use a different type of oil.

Which oil should I use for my car?

We advise reading through your vehicle’s owner’s manual. Check the recommended viscosity rating for your car. The majority of owner manuals also provide advice on the type of oil to use in your car.

As previously stated, heed the advice in your owner’s manual; alternatively, you may find it on your oil cap. There will be more factors at play.


The age of your car comes first. High mileage oil is necessary for vehicles with more than 75,000 miles.


The regularity and manner of your driving. Do you only travel a short distance through your town to complete errands? Or do you go more than 50 miles to work each day on the highway? Due to all the stopping and starting that occurs in cities, driving causes additional wear and tear on your car. Your car will likely be operating below its ideal temperature if you are just traveling short distances. We advise using synthetic oil in this situation because it will function better.


Your local climate comes in third. It is advised to use complete synthetic if you reside in a cold climate. It will offer the finest defense. In harsh winter weather, viscosity is crucial. Your oil shouldn’t be too thick to the point where it won’t flow because this will harm the engine. The summertime climate has little impact because your engine often runs at temperatures beyond 200 degrees.

Basically, full synthetic is the best option. But if you’re changing your own oil, be sure to purchase the right viscosity grade.

Consequences of using the wrong oil

  • In the cold, your automobile won’t start.
  • A burning scent is present. In hot areas, this often occurs. Your car might sustain long-term damage as a result, which would be incredibly expensive to fix.
  • Your car begins to leak oil.
  • Your engine is making noises.

The use of the incorrect oil in your car could have other effects. If you do encounter any of these issues, we advise having your automobile serviced right away to avoid further harm. If these side effects are severe, don’t drive—have your automobile towed to a nearby technician.


Full synthetic oil is less frequently used than synthetic mixtures. Full synthetic oil, on the other hand, is becoming more and more popular and is now used almost as frequently as synthetic blend oils. The majority of individuals are changing because they are fascinated by the durability and enhanced performance of full synthetic oils.

In conclusion, we nearly always say full synthetic if you’re still wondering what oil we advise or believe is ideal for your car. Providing that it works with your car. which it will most likely be. Full synthetic oil lasts longer and offers superior protection for your car, reducing the frequency of oil changes.

In the end, the decision is all yours. In comparison to conventional oil, which we neglected to mention, both complete synthetic and synthetic blend oil will provide better protection. because we advise against utilizing it. The two solutions that are best for you are always fully synthetic and synthetic blends. The finest choice is 100% synthetic. I hope you are aware of the ideal oil for your car today.
