Can Frequent Oil Changes Remove Sludge? Shocking Truth!

One thing for sure is that motor oil can develop into sludge faster than you think. Sludge is known to be a dark gel-like substance that is form by oxidation and contamination of the engine. It can definitely affect the performance of the engine by reducing its ability to lubricate the moving parts and may even cause damage to your car if it not cleared out.

However, you might have heard of theories that recommends changing the engine oil more frequently since it helps remove sludge and doesn’t allow it to form overall.

In this article, we are going to explain everything you need to know about engine sludge and whether frequently oil change helps to remove it.

The Importance of Regular Oil Changes

We think it is best to perform a regular oil change as it helps to keep your engine’s interval clean. By simply changing your engine oil will remove all debris that have been created by the friction of your engine as well as allowing maximum lubrication at all times. Having a well lubricated engine is important since it enables fewer restriction on the moving parts, allowing them to work effectively.

Can Frequent Oil Changes Remove Sludge?

Can Frequent Oil Changes Remove Sludge

The short answer is yes. If you take the time out to change your engine oil on a regular basis then it can remove sludge and other harmful contaminants. If it’s a case where the oil is synthetic then it is even better.

The reason for this is because synthetic oil is great at removing sludge, varnish and other carbon buildup. We appreciate the fact of how effective synthetic oil is as it helps to keep the engine clean. If you decide to change the engine in a short time frame, the drain oil will come out clean, if not then you know something is clearly wrong.

With that said, conventional oil is not the same as synthetic oil when it comes to its effectiveness. They tend to have a higher chance of leaving contaminants behind that needs to be removed as soon as possible.

What Does Sludge Do to An Engine?

We all know by now how complex and precise a engine actually is. So, in order for it to perform effectively it requires the right amount of inputs and oil plays a very important role with this. It’s safe to say that the thickness and viscosity of the oils are known to be measured in weights.

For performance and longetivity, your engine actually needs a specific type of oil type, amount and weight. Sludge is harmful since it is considered to be a thick contaminant that reduces the amount and viscosity of the oil.

How to Remove Engine Oil Sludge?

It is relatively easy to remove sludge from your engine. The only thing you have to do is follow the oil change and maintenance that your vehicle manufacturer recommend.

Frequently changing your engine oil on a regular basis is always a good thing to do as it ensures your oil is always clean. We know for sure that a lot of people haven’t been following the maintenance on their vehicle closely but there is no need to worry because we’ve got you covered since there are other methods you can implement.

Use a High Quality Engine Flush

There is no doubt that using a engi be flush is one of the most effective and easiest way to actually remove sludge from the engine. The reason for this is because engine flush utilize an additive that contains detergent that are used to dissolve the contaminants in your engine oil. You can use this high-quality chemical sludge remover which goes by the name LiquiMoly engine flush.

In order to perform a engine flush you’ll have to prepare your chemical sludge remover first. The product that we’ve listed is of high-quality and should be able to get the job done effectively. Remember we only recommend buying from our trusted source to get the right quality product.

At this point, you’ll need to add the chemical sludge remover to the old oil in your engine and turn the engine on while the car is in parked. You should let the engine idle for roughly 20 minutes. This will give the chemical solution enough time to dissolve all the sludge in the old oil.

Now, you can go ahead and change the oil as usual. Upon draining the old engine oil, the sludge will be drained out as well.

What Problems Can Oil Sludge Cause to An Engine?

The biggest issue you’re likely to face when there is oil sludge is that it affect the natural flow if oil throughout the engine. When there is a poor oil circulation, it results in an increase of friction and cause overheating to occur. At this point, the heat will take a toll on the moving metal parts within the engine which can lead to you having to get an expensive engine repai.

How Do I Prevent Motor Oil Sludge in My Car?

The most effective way to prevent oil sludge from happening is to frequently change your engine oil. So, if it’s a case where your engine is always forming sludge and other buildups, then the best thing you can do is to change your engine oil every 3,000 miles or every three month.

Also, if you are currently using conventional oil, then we highly recommend switching to synthetic oil just to prevent oil sludge from forming. The reason why we recommend this is because synthetic oil is more effective when it comes to removing carbon buildups, and deposits which will help the engine to stay clean at all times.

It is also known to last a lot longer when compared to conventional oil. Therefore you won’t necessarily need regular oil change when you are using synthetic oil.


As you can see, sludge tend to take a toll on the engine which sometimes results in it being damaged. This is why we recommend using synthetic oil since it helps remove engine sludge and keep the engine clean.

If somehow you notice sludge in your engine even after frequently changing the oil, then something is definitely wrong which means that you should visit your mechanic to get the issue solve.
