The Conventional Oil Guide: Is It The Right Oil For Your Car?

September 9, 2021

Conventional oil is popular engine oil that’s highly affordable

But is it right for your car?

And what is conventional oil in the first place?

In this article, we’ll answer those questions and other related queries about conventional oil. We’ll also cover the benefits of using conventional oil

Let’s begin!

What Is Conventional Oil?

Conventional oil, also called mineral oil or regular oil, is an engine oil used for lubrication and greater engine protection. It’s a type of engine oil that is manufactured from refined crude oil. 

How is this done?

When heated to various temperatures, crude oil leaves behind a heavier oil that becomes the base oil for conventional motor oil. Certain additives are then added to the less refined base oil for additional performance benefits and greater engine protection. 

Conventional oil isn’t as refined as synthetic engine oil and synthetic blend oil), but it still serves various purposes well. 

These purposes include:

So what’s so special about conventional oil?

What Are The Benefits Of Conventional Oil?

Although most car manufacturers recommend using synthetic or synthetic blend oil, mineral oil has many inherent advantages. 

They are:     

1. It is highly cost-effective and economical. 

Synthetic motor oil may cost twice as much as regular oil. In contrast, conventional motor oil is very cheap and easily available. And if you follow a regular oil change schedule and don’t practice extreme driving habits, you won’t need to invest in expensive synthetic motor oil.

2. Conventional oil is better suited for older engines 

Older engines (more than 75,000 miles on them) will experience more engine wear on their inner gears and moving engine parts. 

Conventional oil is better suited for older cars since it has a higher viscosity than synthetic oil. It results in better lubrication and a reduced chance of grinding gears and engine wear due to a slower flow.

Conventional oil also performs moderately well under low temperatures. It’s also likely that your vehicle engine used conventional oil when you first bought it. 

Note: You may also want to switch to high mileage oil for older engines. High mileage oil is specially formulated for cars with more than 75,000 miles on them. 

Clearly, conventional oil comes with a host of benefits.

But are conventional oils the right choice for your car?

Is Conventional Oil Right For My Car?

In reality, there is no ‘bad’ motor oil. 

And unless you drive a high-performance vehicle, you can always use mineral oil. 

Many conventional oils contain important additives that help with better engine performance and provide engine protection against friction and sludge formation. As long as these oils comply with industry standards, they’re safe to use and can be good for your car.

You should also refer to your vehicle’s manufacturer recommendations and manual to determine whether conventional engine oil will suit your vehicle. 

Keeping that in mind, let’s look at other related queries about traditional motor oil.  

4 FAQs About Conventional Oil

Let’s take a look at some commonly asked questions about regular engine oil.

1. How Long Is Conventional Oil Good For?

Conventional motor oil can stay good for up to five years

However, it’s difficult to determine the exact shelf life of motor oil.

To get the most out of your oil, you should ensure that you store it right — in an airtight container, away from direct sunlight. 

When in your engine, conventional oil can last for up to 7000 miles if you practice normal driving habits. 

For people who fall under a severe maintenance schedule — which is when you do a lot of heavy towing, off-roading, stop-and-go driving or short trips in extremely high temperatures or low temperatures — this interval is lower. 

This is because the conventional motor oil in your engine will go bad faster than usual.

2. How Often Should I Change My Oil?

The most recommended oil change interval is suggested to be between 3000-5000 miles. However, you can go up to 7000 miles with conventional oil in some cases.

As always, it depends on your driving habits and car type. 

Older engines and extreme driving conditions will require a more regular oil change. 

Note that conventional oil change intervals will be different from synthetic oil change intervals. The former can usually go up to 5000-7000 miles, while a synthetic oil change may be required every 7000-10,000 miles (or more).

3. What Happens If I Wait Too Long For An Oil Change?

If your car is long overdue for a conventional oil change, it will start exhibiting symptoms like greater engine noise, sludge, and inefficiency in performance. 

You can use the car’s dipstick to check your conventional oil.

Here’s how to spot when your conventional oil needs changing:

In addition to these signs, conventional oils will deteriorate the longer you wait to change them. Ultimately, it may lead to complete engine failure or other severe issues.

4. Conventional Oil Vs. Synthetic Oil: What’s The Difference? 

While conventional and synthetic oil both contains base oil and additives, synthetic oil is more refined than the former and thus has fewer impurities. 

Synthetic motor oil is man-made and refined in the factory. 

It consists of various chemical compounds and synthetic additives.

Compared to conventional oil, synthetic engine oil has a better viscosity and is more resistant to extremely high temperatures. It doesn’t break down very easily, and therefore has a longer oil change interval. It also contains a higher quality base oil with fewer impurities.

On the downside, synthetic engine oil is far more expensive than conventional oil. 

Most newer vehicles with modern engines use synthetic blend oil. 

It’s cheaper than synthetic oil and contains a higher quality base oil with fewer impurities than mineral oil. 

Closing Thoughts

Conventional motor oil has many benefits, but the best of all is that it is substantially cheaper than any other oil. 

Just remember to maintain a routine oil change interval, and you’ll be looking at better engine performance with adequate lubrication.
