Features and Benefits

A Promise of Protection to Your Pump
No matter you use an air compressor or vacuum pump, you won’t be compromising the quality of performance and security for it. DEWALT D55001 is a 1-quart pack, made of premium-grade synthetic material.

It’s good at Dealing with Extreme Temperature
In many cases, air compressors fail due to excessive temperature and the lubricant’s inability to eat that up. But DeWalt is aware of the situation and made this lubricant work at even the highest temperature a compressor system can reach.

It Doesn’t Let Any Carbon Buildup Take Place
The main reason why we invest in synthetic air compressor oil is, we don’t want any carbon build-up into the valves. This model serves us precisely with that.

Anti-wear Protection
Wearing out parts is one of the common issues that every automotive owner hates. This oil will fully work in your favor and protest the wearing as much as possible.

It’s good to go for 200 Hours
Once you fill your compressor up with this best synthetic air compressor oil, it will be good to go for the next 200 hours of operation. So, you’ll be free of worries for almost and year.

Dewalt itself is the guarantor of the air compressor we’ve just talked about. Starting from the protection, it provides lubrication, wearing-less function, a long-lasting lifetime of the compressor, and so on. What do you think of this oil?

What is the compressor oil?

No matter you have an automobile vehicle or you run a high-performance internal combustion engine, you need to keep the air compressor smooth. To do that, the kit we use almost every time is the air compressor oil.

Here is the dictionary definition of it-

Air compressor oil is a chemical solution formulated from highly refined additives and a paraffinic base. The purpose of this solution is to produce lubrication, resistance from friction, diminishing the noise, and enhance the performance of an air compressor.

There are many ISO viscosity grades to define variations of air compressor oils at different extents. But the sole purpose of all of them is the same.

Uses and Benefits of Air Compressor Oil

No matter whatever the application is, air compressor oils are a must-to-have part of the whole compressor system. It has some uses, each impacting the overall performance of the compressor.

Here is a list of each of the benefits that we can receive from a good quality air compressor-

Resistance to Oxidation and Thermal Degradation

This property of air compressor oils helps to reduce the deposit of carbon. Also, deduced the amount of oxidation and thermal degradation helps to enhance the lifetime of the compressor.

Anti-wear Protection

Again, air compressor oils are good at reducing wear. And that eventually enhances the lifetime of the compressor. Also, you have to do the least amount of maintenance works in this way.

Corrosion and Rust Protection

No one wants his air compressor to be blown away by corrosion and rust. A good quality air compressor might be your companion right there.

Releases of Foam and Air

Rapid release of foam and air from the combustion chamber helps with the lifespan of the components. It helps to aerate the ingredients and to prevent cavitation damage to it.

Water Separation from Oil

Carryover to down-strip equipment may leave a severe impact on the performance of the air compressor. And good quality oil helps to deduce that.

What kind of air compressor oil types do I need?

When you are up to find the best air compressor oil to use, you’ll be blown up with hundreds of options ahead of you. It’s such a chore and to see the right one needs some expert hand.

The type of air compressor that you should use massively depends on the standard and synthetic blend of the product. From manufacturer to manufacturer, they vary a lot.

But typically, the ideal recommendation is to use oils with 20 weights or 30 weights. Both of them are of a non-detergent type. Also, there are intense debates as well as misconceptions among motor oil vs. compressor oil, synthetic oil vs. non-synthetic oil, and so on.

However, we have got some head-to-head comparisons of different kinds of oils and lubricants. Go through the points below and get a complete idea of what type of air compressor oil you should use.

Air compressor oil vs motor oil 

Air compressor oil vs motor oil 

We’ve seen many new users use motor oils in their air compressors, which is entirely wrong. Compressor oils are specially designed for air compressors, where motor oils are for motors of trucks, cars, etc.

Motor oil contains some detergent actually in it. And that’s because such ingredients are helpful for internal combustion, which motors have to deal with a lot.

But a compressor doesn’t have any such necessity. The presence of detergent causes a build-up of carbon, which is eventually bad for the health of the air compressor.

Moving forward, using motor oil in your air compressor may ruin the warranty of your compressor. Usually, when the manufacturers find that you are using non-standard motor oil in your compressor, they deny providing the warranty or guaranty.

Our last advice is to avoid any motor oils or oils that contain detergent in them for your air compressor. Non-detergent air compressor oils are 20 to 30w, and they are available in any local auto parts store.

If your thought is to buy only one oil for the whole automobile (motor, air compressor, etc.), then we would insist on reconsidering your opinion. Each of the parts has its demands. And you as the owner have to hear that up.

Recommended Motor Oil on Amazon: 

AmazonBasics Full Synthetic Motor Oil - 5W-30 - 5 Quart
  • For best performance, follow the manufacturer's recommendations in your vehicle owner’s manual.
  • Formulated for longer drain intervals
  • Helps prevent build up that can cause rust and corrosion
  • Reduces friction for less engine wear
  • High resistance to viscosity and thermal breakdown

Synthetic vs Standard Air Compressor Oil 

Now, we have to disclose the debate between standard air compressor oil and synthetic compressor oil. Both of them are widely is used for air compressors. But inaction, they have their features that you should be aware of.

The fact that matters while choosing between standard and synthetic air compressors is- how often you are using them on your compressor.

A standard compressor would be okay to use for cases where the air compressor isn’t in use a lot. For occasionally used compressors, they are occupied in a mid and light level of workloads, and the working hours are not even high. So, conventional compressors oil will be just fine.

Now, come to the point of synthetic air compressor oils. As you know, the price point of the synthetic air compressor is way higher than standard oils. So, the case of uses should have enough reasons to worth such an investment.

What we are trying to say is, synthetic air compressor oil is for professional cases where the frequency of using an air compressor is too high. By the word ‘too high,’ we mean that at least thrice a week. Good quality synthetic compressor oil should be there to provide better protection from overheating, and lubrication.

Also, synthetic air compressor oils are likely to have a broader range of temperatures when your compressor is running under cold temperatures. Also, synthetic compressors are likely to provide smoother operation as long as long-lasting performance.

According to many users’ perspectives, synthetic air compressor oils are better regarding performance and accuracy.

100 synthetic oil vs fully synthetic

We’ve got a lot of questions posted on forums about the difference between 100 synthetic oil and fully synthetic oil. In this section, we are going to showcase the difference between them.

By 100 synthetic oil or 100% synthetic oil, there develops new compounds or molecules. They are capable of providing better lubrication, more protection, and more resistance to the pressure that builds up inside your air compressor.

A manufacturer, who develops 100 synthetic oils, can control the quality of each of the drops of the oil. The quality of the oil is refined and contains the same class as mineral-based oil.

Some of my favorite 100% synthetic oils are Motul’s High Tech 8100 and 300V ranges. In this model, each of the drops of the oil is purely synthesized.

Fully synthetic oil on the other hand is just the regular synthetic oil that you get to find in any market. They are good so far. But there are some drawbacks if you compare them with 100 synthetic oils.

We are going to put them down as a list-

First thing first, there is no strict regulation or definition of what we call ‘fully synthetic oil.’ There are many cases where the companies claim to make fully synthetic oils but what they do is just highly refined synthesize the raw materials.

You have to pay some severe bucks when you’re up for buying fully synthetic oils. But what you end up with may not be adequately synthesized oil at all.

The fully synthesized oils have a percentage with them, which is not often disclosed. In most cases, they are like 90%, 60%, or even 2% synthetic. And the more serious problem is, you don’t know this actual number.

Recommended 100 Synthetic Oil on Amazon: 

Motul 7100 4T 5W40 100% Synthetic Engine Oil 4 Liters (104087)
  • For best performance, follow the manufacturer's recommendations in your vehicle owner’s manual.
  • 100% Synthetic Ester
  • Formulated To Meet The Latest Manufacturers' Specifications
  • Improved High Temperature Deposit Protection And Sludge Control
  • Ensures Optimum Clutch Performance At Start-Up, Acceleration, And Full Speed

Vacuum pump oil vs compressor oil

Vacuum pump oil vs compressor oil

You may have heard to use the term ‘compressor and vacuum lubricant’ quite often. The fact is, many companies treat these two types of lubricant oils as one. But actually, they are not.

Go through the section below to understand the difference between them-

Vacuum pump oil is usually, made out of a high-performance mineral base. The formula or this oil contains an excellent grade of anti-wearing properties. So, the induce proper lubrication among the parts of a vacuum pump. They also secure the vacuum pumps with long-lasting durability and protection from corrosion and rust.

Vacuum pump oils are also known for their property of containing anti-oxidants. This is impactful when it comes to enhancing the service life of the lubricants.

As a result, you don’t have to use lubricants frequently to get the best performance out of your vacuum pump.

Air compressor oils, on the other hand, are manufactured to reduce the carbon buildup between the compressor valves. Which eventually, results in a long-lasting air compressor? There are many variations of air compressor oils regarding viscosity, organic chemicals, and so on.

In this post, you can already see some variations of air compressor oils. And choosing the right one from them takes a toll on long-lasting research. However, the best kind of air compressor oil is known as synthetic oils, and that’s what we are talking about throughout the whole post.

Recommended Vacuum Pump Oil on Amazon:

  • 1 quart (32 oz.) bottle

How to Change Air Compressor Oil?

Once you get the best synthetic air compressor in your hands, it’s time to change that with the previously put oil.  However, we will take you through a set of steps on how to do that.

Let’s start-

Step 1: Locate the Drain Plug and Remove Obstacles

Your first duty is to find where the drain plug is. Also, there can be many obstacles throughout the way of the draining process. You have to locate that as well. If you don’t do so, the whole process of draining can turn into a mess.

Step 2: Catch the Old Oil

Already there can be the presence of precvio9usly put air compressor oil. Find a bottle or something to collect that and empty up the whole inside. Also, you can do that with a drain pan or small container.

While draining the oil out, secure the position of the drain plug and drain pan. In some of the compressors, you may need to hold the other end of them as well.

Once the draining process is done, put back the drain plug into its position.

Step 3: Find the Fill Cap

The third step is to locate the fill cap and refill the compressor with the new oil. You can take the help of a small funnel to do that, and that will prevent slipping off oils.

Remember, you are advised to refill the air compressor as per the instructor’s manual. So, make sure to have a firm idea about that.

While doing the refill, keep an eye on the fill level to check whether it has got a sufficient amount of oil or not. Make sure that you don’t refill the oil at an excessive level.

Step 4: Recycle the Old Oil

There are many uses of used air compressor oil. Once you’re done with filling up your compressor with the new oil, ask at the local auto parts shop whether they have any way to recycle the old compressor oil or not.

Once done, you’re good with the whole changing process.

Air compressor oil substitute

Although, we are not recommending you to use anything else instead of air compressor oils. But there have been a lot of places where people are getting over with using so. Mainly, for portable air compressors, many engineers use automotive transmission fluid, also known as ATF.

In this section, let us give you a brief on the fact-

Automatic Transmission Fluids (ATF) is a kind of lubricant used in industrial-grade automobiles. Many properties in ATFs suit the necessity of a compressor fluid as well.

For example, in an automotive system, the ATF performs the task of lubricating, cooling parts, keeping the deposits away, play the role of a hydraulic medium, and reduce friction forces among elements.

You may already see similarities between what air compressor oil can do, and what ATF does.

But there are some drawbacks as well. If you use ATF instead of compressor oil, there is a good chance of incompatibility between the existing lubricant and the newly put ATF.

Also, the can cause additive issues if your compressor is not a portable type. So, we would recommend you consult with an expert before getting such air compressor oil substitutes in use.
