Best Synthetic Air Compressor Oil [Buying Guide 2021]

In A Hurry !

Well, if you in a hurry, got no spare time, and just want to know which is the best synthetic air compressor oil. Then I’d recommend the Royal Purple 01513 Synfilm Recip 100 as the best companion.

Lubricants are the essential ingredients for the life of the compressor. Conventional or synthetic whatsoever, they satisfy the thirst of the machines.

Though, conventional oils deliver sufficient lubricity. Yet, they can’t effectuate the overall performance and protection offered by the synthetics.

Benefits of Synthetic Oil To Air Compressors

Synthetic oils are tailored to the demands of a specific application. They are more refine and higher in quality than the conventional ones.

Conventional oil descends from crude oil, while synthetic lube takes its source from conventional oil. It is further modified and improved for optimum performance, protection, and lubrication.

The benefits offered by the synthetic compressor oils are above and beyond that those claimed by the conventional lubes. We sum up a few FYI.

  • Synthetic oil prevents carbon buildup.
  • They reduce the wear and control of the scaling deposits.
  • Eliminates the excessive consumption of power and energy.
  • Due to their durability over conventional oils, they save you extra oil costs.
  • Synthetic oils don’t deteriorate easily. Thus, reduces the oil-change out hassle.
  • They clear the engine or pump from the sludge. Thus, Increasing the compressor’s lifespan.
  • Built to resist wear at high temperatures. The extreme cold doesn’t affect the flow. Thus, the compressor works smoothly in summers and starts quicker in winters.

Moving on we did dig up the best synthetic air compressor oil and dished it up for you. Explore the chemistry developed in the labs that makes a big difference at the job site.

Best Synthetic Air Compressor Oil [Buying Guide 2021]

Starting the journey now with the critical components that steer you to shop around. Have an insight into basic terminology, before getting through the reviews.

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.

In the winters, one of the major issues experienced is the difficulty in starting up the machine. Improperly weighted lubricant is one of the major causes. Therefore, it is recommended to fill up the tank with low viscosity oil.

On the other hand, in summers, you have to quench the thirst of the compressor with high-grade oil.

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.

Satisfy the craving of the tank with the recommended grade oil while keeping the climatic condition in view. Consequently, experience the prolonged streamlined performance of the equipment.

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 breakdown 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.

You should select the viscosity of the oil according to the weather conditions. Low viscosity lubricant will serve great in the cold weather. However, in summers, you should pour high-viscosity oil in 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 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 and muddy. 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, a balanced lubricant in features and price march on with green signal for final purchase.

Besides, the oil change frequency also affects the overall budget on a long-term basis if you compromise on the lubricant quality.

Best Synthetic Air Compressor Oil FAQs

Q: What Oil To Use In Air Compressor?

Ans: The manufacturers and air compressor experts always recommend compressor oil depending mainly on air compressor type and weather conditions you’re living in. In colder temperatures and regions, SAE 20 oil due to its lower viscosity/weight. While for hotter regions and temperatures SAE 30 is best due to its high viscosity. Also, make sure to check which type you’re using a synthetic blend or full synthetic air compressor oil.

Q: How Much Oil Does An Air Compressor Take?

Ans: Usually, it depends on the size of an air compressor. Larger industrial air compressors require more oil than the normal shop or garage compressors. The general norm of oil holding capacity of most compressors is 1 Gallon (4L).

Q: How To Add Oil To Air Compressor?

Ans: Below are simple step by step instructions for adding oil to your air compressor:
1. Check the location of the oil draining cap/plug.
2. Put an oil filling pan write below the cap to collect the previous oil.
3. Remove the plug/cap by using an adjustable wrench.
4. Now, slowly put the manufacturer’s recommended oil in it.
5. Monitor the dipstick or sight glass for oil level.
6. Once filled then replace the plug/cap on the pump.
