What is the Major Difference Between Conventional and Synthetic Oil?

Let’s say you’re in the market for a new oil. You’ve narrowed it down to two types, trying to decide which one to buy. One is a conventional oil, and the other is a synthetic oil. So, what’s the difference? The difference between conventional and synthetic oil is straightforward.

Conventional oil is made from crude oil, while synthetic oil is made from artificial chemicals. This oil is cheaper to produce, but it also has more impurities. On the other hand, synthetic oil is more expensive to produce, but it has fewer impurities.

Because of its purity, synthetic oil performs better than conventional oil in all areas. It lasts longer, runs cooler, and produces less friction.

Synthetic oil also has a higher viscosity index, which means it resists thinning in extreme temperatures. As a result, synthetic oil is ideal for high-performance cars and engines subject to high-stress levels.

So, if you’re looking for the best possible performance from your car, go with synthetic oil. In this blog post, we’ll have an in-depth look at the major difference between conventional and synthetic oil.

Major Difference Between Conventional and Synthetic Oil

They make conventional oil by crushing or heating crude oil. On the other hand, synthetic oil is chemically identical to conventional oil but they create them in a lab using a process called hydrocracking.

The result is a more efficient and cost-effective oil. Synthetic oil is more resistant to high temperatures and friction, making it more durable.

Synthetic oil better protects the engine of a car, resulting in a longer engine lifespan. This oil has good resistance to friction which increases its power and efficiency. Therefore, synthetic oil is more beneficial than conventional oil.

Synthetic oil is perfect, especially for people who are on the road and need to maintain a reliable engine. One of the main advantages of synthetic oil is that it lasts a long time. That means you don’t have to worry about changing your oil often. And that’s important for people who spend a lot of time on the roads.

Synthetic oil performs better in extreme temperatures than conventional oil, making it a better choice for those who drive in harsh conditions, such as heavy snow or the desert.

Synthetic Oil – Overview

While all oils are created from plants, they are made in the industry in two different ways. One of these ways is called conventional oil.

Conventional oil comes from crude oil, you can naturally find them in underground reservoirs. These reservoirs can take millions of years to form and are often located in regions with difficult weather conditions.

While they make synthetic oil from crude oil, it goes through a process of refining and purification that makes it of a higher quality.

Synthetic oils exists through a chemical process and can be twenty-four hours. These oils are also of a lower cost, which makes them more desirable for consumers.

This oil is a great choice for both performance and classic cars. It from a blend of different petroleum products and has a higher viscosity than regular oil. It means that synthetic oil stays in liquid form at higher temperatures.

Besides, synthetic oil also provides better protection for the engine, reducing wear and tear and helping the engine last longer. Lastly, synthetic oil does not produce as much pollution as conventional oil.

What Are the Pros and Cons of Synthetic Oil?

There are pros and cons to using synthetic oil in your car. Here are the most important ones:

• Synthetic oil lasts longer than conventional oil, so you don’t have to change it often.
• It’s more resistant to heat and stress, so it’s a good choice for high-performance cars.
• It’s better for the environment than conventional oil.

• It’s more expensive than conventional oil.
• It can damage your car’s engine if you don’t use it correctly.
• It can be challenging to find in some areas.

Conventional Oil – Overview

The benefits of using conventional oil are: less expensive than synthetic, available at most gas stations, and helps protect your engine. Synthetic oil is more expensive than conventional oil.

It is not readily available at gas stations, and it’s not recommendable for older cars. Conventional oil more effective at protecting your car’s engine.

If you’re in the market for a new car, make sure your mechanic checks the oil and replaces it as needed to keep your car running smoothly.
Conventional oil comes from naturally occurring crude oil. It is but can become bad ver time because of its impurities.

As we said earlier, synthetic oil comes from petrochemicals and has a higher viscosity and lower gas and sulfur content. Synthetic oil helps your engine run more quietly and prevents engine wear and tear. Also, it helps your car release fewer emissions into the air.

What Are the Pros and Cons of Conventional Oil?

Let’s take a look at the pros and cons of using conventional oil in your vehicle:

• Conventional is cheaper than synthetic
• It’s available at most gas stations

• The oil doesn’t lubricate as well as synthetic oil
• It doesn’t protect your engine as well as synthetic oil
• Causes engine issues over time

How Do I Choose the Right Oil for My Car?

Choosing the right oil for your car can take time to know where to start. Do you go with either? What’s the simplified difference, and which one is right for you?

Here’s a breakdown of the differences between conventional and synthetic oil:

• Conventional oil is made from crude oil extracted from the ground.
• Synthetic oil is made from petroleum-based or plant-based chemicals.
• Conventional oil is less expensive than synthetic oil.
• Synthetic oil lasts longer than conventional oil and produces less pollution.
• Conventional oil needs to be changed more often than synthetic oil.

So, which one is right for you? That depends on your needs and budget. If you’re looking for a cheap option that will need to be changed more often, go with conventional oil. If you’re looking for a more expensive option that will last longer and produce less pollution, go with synthetic oil. Autozone offers incredible oil types.

Frequently Asked Questions:

What is the primary difference between conventional and synthetic motor oil?

The primary difference is in the composition of the oil. Conventional oil is derived from crude oil and contains impurities, while synthetic oil is engineered in a laboratory and is more refined and consistent in its composition.

Which one is better for my vehicle: conventional or synthetic oil?

The choice between conventional and synthetic oil depends on your vehicle, its age, your driving habits, and the manufacturer’s recommendations. In many cases, newer vehicles and high-performance engines benefit from synthetic oil, while older vehicles may use conventional oil.

Are there any advantages to using synthetic oil over conventional oil?

Synthetic oil offers several advantages, including better high-temperature stability, improved cold-start performance, reduced engine wear, longer oil change intervals, and improved fuel efficiency.

Is synthetic oil more expensive than conventional oil?

Yes, synthetic oil is generally more expensive than conventional oil. However, it can offer cost savings in the long run due to longer oil change intervals and potential engine protection benefits.

Can I switch from conventional oil to synthetic oil in my vehicle?

Yes, in most cases, you can switch from conventional oil to synthetic oil. However, it’s essential to follow the manufacturer’s recommendations and ensure compatibility with your vehicle’s engine.


The biggest difference between conventional and synthetic oil is the refining process. Conventional oil is extracted from the ground, while synthetic oil is made in a lab. The refining process matters because it affects the final product.

One is refined to remove impurities, while the is refined to create a uniform product. It means that synthetic oil is more consistent than conventional oil and less likely to break down under extreme conditions.

Synthetic oil is the better option if you’re looking for a high-quality oil that can withstand extreme conditions. Conventional oil is a good choice for everyday use because it’s more affordable and easier to find. Get more car maintenance tips from Vehiclesforall.
