Best Synthetic Air Compressor Oil [Buying Guide 2021]

Why You Should Choose 01513 Royal Purple?

“Time is Money” as the Quote speaks itself… What’s really important is to save your time and money. So, following the quote, I am giving you “My Personal Recommendation” on the best synthetic compressor oil. Based on our deep analysis, and hard research, the 01513 Royal Purple is overall best due to the Synerlec Additives that prevents engine rust and corrosion. Plus, it cheapest compared to others.

Synthetic compressor oils are one of the essential ingredients for an air compressor to keep it cool and work properly. Whether you’re using a small oil-lubricated compressor or if it’s commercial-grade big compressors that come with 20, 30, 60, 80-gallon ranges.

No matter which size of air compressor if they oil-lubricated then getting the best synthetic air compressor oil is essential. Let me give you an example.

I usually make an analogy of an “Angry Man” here. Meaning when you’re hot n burning with anger… You get a drink for yourself to keep it cool or cool it down. That’s what I am talking about. These machines work the same way as we ourselves do.

On the technical side, air compressor synthetic oils fulfill the most critical job of lubricating the internal components of your compressor. Over time the lube in compressor internal components starts becoming dryer.

Due to the roughness and simultaneous collision of components with each other, the worst enemy of your compressor is born i.e., “The Friction”.

The friction in return works as a “Hitman” by generating excessive heat that damages your compressor from inside.

Friction – The Hitman

Friction can be defined as the resistance in movement between two bodies, or elements produced due to the velocity, surface roughness, and simultaneous collision of those components with each other.

That’s why synthetic compressor oils are used to prevent all these problems. They are specially designed based on the machine’s demand. They are more refined and higher in quality than conventional oils. Thus grant more benefits compared to other oils.

Here is a brief list of benefits that I made:

Benefits of Synthetic Oil To Air Compressors
  • Prevents carbon buildup
  • Control scaling deposits in compressor
  • Reduces friction and wear in internal parts
  • Highly Durable & doesn’t deteriorate easily
  • Protects the compressor from rust and corrosion
  • Eliminates excessive power and energy consumption
  • Helps compressor in resisting wear at high temperatures
  • Helps in the “Quicker Compressor Starts” even in winters
  • Efficiently cleans up the engine and pump sludge to extend the compressor’s lifespan

So, getting the best synthetic air compressor oil is really important. As it’ll give optimum protection, lubrication, and improve your compressor’s performance. And that’s my core reason to write this buying guide.

Best Synthetic Air Compressor Oil 2021 [Buying Guide]

Let’s begin the analysis with some crucial aspects that’ll give you really important info on what to look for before choosing the synthetic oil for air compressor.

The Viscosity

Viscosity is a vital factor to consider before buying the lubricant. Before getting acquainted with it, let me inform you that viscosity, grade, or weight are alike terms. We will use either of them, don’t get confused.

Since viscosity is related to the thickness of the oil, so you can think of how easy to pour the oil into the tank. However, the temperature has a critical effect on the grade of the oil which I have discussed below in “Operating Range of Temperature”.

You can determine the grade of the lubricant from the label on the pack. It is shown in either SAE or ISO. A low value means low viscosity and vice versa.

Importance of Additives

Additives are the chemicals to enhance the lubricity of the oil and extend the compressor’s life. The oil may become contaminated or break down early without them. Or you can say the parts will wear soon in their absence.

The percentage of additives present in the oil depends on the use and operating conditions. When added they have several benefits such as they improve the viscosity and reduce the friction between the parts.

Moreover, they prevent contamination and the formation of oil sludge. The anti-oxidant, and anti-corrosion capabilities protect the parts of the engine. Being anti-wax and anti-foam, they refine and smooth the working of the compressor.

The Operating Range of Temperature

The overall performance of the oil depends on the temperature. Severe cold or sizzling weather will greatly affect the lubricity of the oil. Such as difficulty in starting up the machine. Improperly weighted lubricant is one of the major causes.

You should select the viscosity of the oil according to the weather conditions. Low viscosity lubricant will serve great in cold weather. However, in summers, you should pour high-viscosity oil into your compressor for the optimum output.

Be informed that heat generated during the pumping also suppresses the performance. Generally, the operating conditions are labeled on the product to get the consistent performance the whole year. However, operating beyond the suggested values will result in the malfunctioning of the equipment.

The Oil Change Frequency

Oil change frequency depends on the compressor type and its operating time. However, the recommended change-out time for reciprocating air compressors is three months or 700-800 hours of use. While for rotating ones, the oil exchange interval is 7000 to 8000 hours of service.

The big industrial giants require to change the lubricant in a shorter pause of 300 hours of operation. As time moves on, the oil gets Thicker, Muddier, and “Darker Than Black”. At this stage, it will lessen the lubricity and increase the friction.

This oil mess will degrade the performance and efficiency of the compressor. If you let the oil course through the compressor body for longer recklessly, It’ll cause wear and damage. A hit to your budget as well.

Quantity of Oil

Diet your compressor to its full. Not clear? Well, you should fill up the oil tank according to the tank size or as per requirement.

There are two scenarios for oil replenishment. The first is to refill the oil wholly after a suggested period. However, the second scenario is more crucial, as the oil level may drop due to consumption or leakage.

The lower oil level will stimulate the wear of the components by increasing the friction. Thus, to prevent this damage, you should check and keep the lubricant in the right amount.

Finally, The Price

Whenever we go shopping, we buy items mindful of our pockets. No doubt, everyone demands high featured products at a reasonable cost. Keep the same in view.

Although the prices also depend on the quantity you gonna get. Another thing you should consider is the oil change frequency also affects the overall budget on a long-term basis if you compromise on the lubricant quality.

My Personal Recommendation

That’s all from me and on my part, I’ll be going for the “Royal Purple 01513”. It’s the best synthetic air compressor oil for me because I don’t use refrigerant compressors. Plus, I am not bothered with the All-season issue as well.

Speaking of All-Season, the Powermate Air Compressor Oil being a 1 QT. full synthetic oil works fine in both higher and lower temperatures.

On the other hand, the OEM All Season Select Air Compressor Oil is a bit unique. Because it works only for Ingersoll Rand compressors. One more thing, this dude supports all models of Ingersoll Rand compressors.

The DeWalt D55001 I think is specially made for DeWalt compressors. But, that’s just my opinion on this one. But, it seems it works fine with all other compressors as well. But, be sharp on that. Even a synthetic oil that doesn’t suit your compressor can cause problems.

Finally the Amsoil Compressor Oil… just like the above OEM All Season it’s also a bit intriguing that it is designed as rotatory and reciprocating compressor oil. But, it also works with vacuum and pressure washer pumps.

As for the decision, I do suggest you ask your manufacturer about the oil your compressor wants and If you have decided then I am here for you.
