Can You Use Regular Oil After Synthetic? (Answered)

Using the right type of engine oil is important to keep your car engine in good condition. Many people prefer using synthetic oil instead of regular conventional oil for their engines. In this article, we will discuss the pros and cons of regular oil and synthetic oil. 

Can you use regular oil after synthetic? 

It’s completely fine to use regular oil after synthetic because they both have the same application. Synthetic oil provides better protection to your engine than regular oils. But switching to regular oil after using synthetic oil won’t cause any damage to the engine nor impact the driving. 

Using the right type of engine oil is an essential part of maintaining your car. Engine oil is supposed to protect the engine and prevent the car from lagging or idling. 

In addition to that, the right type of engine oil will provide you with the best mileage and performance efficiency. 

There are different types of engine oil available in the market. In some cases, the engine manufacturer company recommends the specific type of engine oil required for the engine. 

Generally, there is a conventional regular type of engine oil and synthetic engine oils available in the market. You can use the regular one or the synthetic one depending on your choice. 

Some people prefer to use synthetic oil because it provides better protection to your engine and improves the performance as well as the mileage of your car. 

But then again, you may think that it is not possible to switch back to conventional oil when you are using synthetic oil. Both oil types are compatible with each other. 

The conventional engine oil is recommended by the manufacturer company of the engines. So many people tend to use that oil. But there are no drawbacks to using synthetic oil instead of using conventional oil. 

And if you ever consider switching back to conventional oil from using synthetic oil, it’s completely fine. They have the almost same type of application. Both the oils will play the same role to keep your car engine in good condition. 

As a result, switching back to conventional engine oil from synthetic engine oil will not cause any changes to your engine or harm the performance.

Is it OK to put regular oil in after synthetic?  

The right type of engine oil helps to improve the engine performance and efficiency. Generally, most people tend to use regular conventional engine oil for their car engine. 

But some car owners prefer to use synthetic oil because it provides better protection for the engine, compared to the conventional engine oils and has multiple benefits. 

That is why you can use synthetic engine oil in your car engine if it is recommended to use instead of regular engine oil. 

But in case you want to change your mind and switch back to regular oil after using synthetic oil for a long time, it won’t affect the performance or the efficiency of your car engine. 

Because both the engine oils have the almost same type of operations and applications. That is why it is fine to put regular oil in your car engine after using synthetic oil.

Why can’t you go back to regular oil after synthetic?  

The importance of using the right type of engine oil for your car is immense. It helps to improve the driving efficiency of your car and keeps the engine running smoothly. 

That is why you can use regular engine oil that is recommended by the engine manufacturer company. There is a substitute for conventional engine oil that is slightly costlier, which is known as synthetic engine oil. 

Synthetic engine oil is composed of chemically engineered molecules that are designed to provide higher performance and efficiency for your engine than the other oils. 

But once you start using synthetic engine oil, it may become difficult for you to switch back to regular engine oil. The following explains why you cannot use regular engine oil over synthetic engine oil: 

You may lose the engine protection: 

Synthetic engine oil gives better engine protection, switching to the conventional engine oil after using synthetic oil causes the loss of engine production. You may notice smaller changes to engine behavior.

The fuel efficiency and mileage will be gone: 

Synthetic oil helps to provide you with better fuel efficiency and mileage. So, if you switch back to conventional engine oil after using synthetic engine oil, your engine will never be able to provide the fuel efficiency.

It may shorten the service life: 

Synthetic oil is known to provide double service life compared to conventional engine oil because the chemical composition in synthetic oil does not break over time. 

If you go back to the conventional engine oil after synthetic engine oil, it will shorten the service life.

What happens if you use conventional regular oil after synthetic?  

The right type of engine oil is important to keep your car engine running smoothly and provide better fuel efficiency. That is why you need to use engine oil that is recommended by the manufacturer. 

Generally, most people use conventional engine oil. But there is also synthetic engine oil that can provide you with better engine protection. Although synthetic engine oil is a little bit expensive, most people prefer to use it because of its benefits. 

In some cases, you may think about using conventional engine oil after you have used the synthetic engine oil. But this causes some events which may have some effect on the engine. 

The following is a description of the changes that can be noticed as a result of using conventional oils after using synthetic oils:  

Lessens productivity of the synthetic oil: 

When you use regular oil instead of the synthetic engine oil, it lessens the productivity of synthetic oil. It also affects the service life time of the engine.

Creates synthetic blend: 

When you use the conventional engine oil after using the synthetic engine oil, it creates a synthetic blend inside the engine. That means, it will mix the synthetic and conventional engines altogether and create a new blend.

It will save you money: 

The best part about using the conventional engine oil rather than using the synthetic engine oil is that it will save you money.

Can you switch back and forth between synthetic and regular oil? 

Yes, you can switch back and forth between conventional engine oil and synthetic engine oil

Since both these engine oils are made using the same type of compound, and they have almost the same applications, watching back and forth between the synthetic engine oil and regular engine oil will not harm the engine. 

But the best part about using synthetic engine oil is it will be able to provide you with better fuel efficiency, mileage, and engine protection. That is why many people prefer to use synthetic engine oil to extend the lifespan of the engine. 

The synthetic oil will be able to provide your engine with an adequate amount of lubrication performance which a conventional engine oil cannot. 

If you use the engine oil and synthetic engine oil back and forth, it will make a synthetic blend which is a mixture of synthetic and conventional oil.

How to switch from regular oil to synthetic oil?  

If you’re tired of using regular conventional engine oil for your engine and getting average performance, it’s time for you to gear up and change the engine oil type. You can simply switch to synthetic engine oil. 

Synthetic oil has adequate lubrication performance compared to the conventional engine oil that helps to run the car smoothly. 

Synthetic engine oil is composed of chemically engineered molecules that are designed to provide higher performance and better fuel efficiency for your engine. 

Rather than using conventional oils. That is why you can switch to synthetic oil from regular oil very easily. Below is a brief discussion on how to switch from regular oil to synthetic oil: 

Read the manual: 

You need to make sure that your car supports this synthetic engine oil. So, you need to read the manual carefully before applying synthetic engine oil to your car.

Flush the engine: 

It is important to flush your car engine so that the accumulated sludge and a debris can immediately get removed from the car engine. 

Pour the synthetic engine oil: 

Once you’re done flushing your engine, now it’s completely ready to take in the new type of engine oil. Although there can be a little bit of accumulated regular engine oil present in your car, adding synthetic engine oil will make a synthetic blend.

Final thoughts 

You can use regular engine oil after using synthetic engine oil. It will not harm the engine because both of these oils are made using the same type of compound and are used for the same applications. Although the synthetic engine oil is expensive and will provide you with better engine protection.
