Does Synthetic Oil Clean Sludge?

by Chris Lewis.

Are you annoyed about having to address engine sludge issues at every oil change? No matter how careful you try to be with your driving, engine sludge is an issue that’ll keep coming back.

If you’re looking to fix the engine sludge problem, flushing the engine at every oil change will not cut it; you’ll need a long term solution.

One solution most mechanics give out is to use the more expensive synthetic engine oil, but does it work?

Before answering this question, it’s better to give you a more in-depth understanding of what synthetic oil is and why it comes highly recommended.

Types of Engine Oil


The market comes with a wide variety of motor oils; however, we’ll look into the three most common types and how they are different from synthetic oil.

  • Conventional Oil

Conventional oil, better known as mineral oil, is the simplest and most affordable product you’ll find in the market under the motor oil category.

The oil is simply crude oil that has been refined in a factory, with some special additives added to make it stable to use for vehicles.

This type of oil should provide you with a relatively fair amount of performance for a good price range. However, mineral oil is not what you might be looking for, improving the performance or fixing issues in an engine.

  • Fully Synthetic Oil

Compared to the mineral oil we discussed above, synthetic oil is the complete opposite. Unlike mineral oil, this oil is not refined from the naturally available crude oil; instead, it is designed entirely in a laboratory.

Thus, the oil can be very expensive; however, it also ensures peak performance from your vehicle and provides the ultimate protection.

  • Semi-Synthetic Oil

Semi-synthetic oil is quite honestly the best value for money options you’ll find in the market. This oil combines both worlds’ best, creating a hybrid from the mixture of mineral oil and synthetic oils.

They allow an improved performance of the vehicle while also protecting the engine as well.

Even though synthetic oils are one of the more expensive choices you can go for, they are still what we would recommend for you to purchase.

Since these oils are designed precisely with the features and abilities of the engine in mind, they provide benefits that other oils cannot, such as:

  • Tackles Extreme Temperatures

Handling extremely high/low temperatures is one of the most significant advantages of synthetic oil.

The ability to handle such conditions allows the oils to function optimally. Thus, keeping the engine’s performance stable in the most extreme scenarios.

  • Keeps the Engine Fresh

The oil also provides one of the highest protection levels to the engine compared to almost any other oil type.

Its chemical properties keep the engine interior walls safe from ash and any other deposits; thus, keeping the engine clean and clog-free.

  • Offers Higher Range

Synthetic fuels also provide a much longer range between oil extraction or changes. This ability to get a range of around 7000 miles to 10000 miles means the chances of you overusing the engine oil are lower.

Therefore, the damages that usually occurs from overused engine oil are much lower than usual.

  • Resists Oxidation

The synthetic oils are also resistant to all forms of oxidation; thus, it keeps the oil in the engine intact for a longer time, even if left unused.

  • Enhanced Performance

With the lubrication’s improved performance, the engine’s performance should also drastically improve. Smoother movement of the gears and pistons inside the engine means the engine can achieve quicker and higher torque.

Improved torque figures should also improve the engine’s horsepower, giving you a beefier output.

Now that you’re better aware of synthetic oil’s abilities, it’s time for us to answer the big question.

The answer to which is a fortunate Yes! Synthetic oils come with advanced properties that allow them to provide a permanent solution to your engine’s sludge issues.

The powerful chemicals already present in the synthetic oils compound work to break down/ disintegrate the sludge that is present inside your engine.

This sludge then mixes with the engine oil, which is filtered out inside the oil filters present in your car. After the sludge collects in the oil filter, you can easily remove it the next time you replace the oil filter and the engine oil.

But that’s not all; synthetic oil further provides an overall coating to your engine’s interior wall. The prevention of oxidation makes sure no new sludge takes form, thus giving your vehicle overall long term protection.


Now that you’ve gotten the answer to the age-old question, “does synthetic oil clean sludge?” it is time for you to make a decision.

We hope you’ll make the right decision to upgrade to synthetic oil so that your car remains protected for years to come.
