What is the Best Synthetic Air Compressor Oil?

Updated August 11, 2024 by Searchforparts.com

Many people ask, “What oil should I use for an air compressor?” The air compressor is an essential piece of equipment in any workshop. It helps to power tools like nail guns and spray guns, and it can be used to fill up tires or inflate sports balls. But did you know that your air compressor needs oil to work properly?

And if you have the best oil, it’ll work even better.

The oil reduces friction between the moving parts of the compressor, which helps to prolong its lifespan. Over time, the oil will break down and become less effective. This is why it’s important to check the level of oil in your compressor regularly and top it up when necessary.

In this blog post, we are going to provide information on the best five compressor oils, each depending on their ISO grade. If you’re a regular here, you know we’re big fans of Amsoil products. Spoiler alert: Each of the five compressor oils is made by Amsoil. So you know each is a quality product and they are 100% full synthetic oils.

Let’s get started with the five best compressor oils from Amsoil!

The Best Synthetic Air Compressor Oil by ISO Grade

As mentioned above, we couldn’t recommend Amsoil enough when it comes to compressor oils. The five we want to share, based on ISO grade, are:

Synthetic Compressor Oil – ISO 32, SAE 10W
Synthetic Compressor Oil – ISO 46, SAE 20
Synthetic Compressor Oil – ISO 68, SAE 30
Synthetic Compressor Oil – ISO 100, SAE 30/40
SIROCCO™ Compressor Oil – ISO-32/46

Each of these air compressor oils has the same types of efficiency, wear reduction, heat resistance, and more. We’re going to list the oil and then provide one particular snapshot of each. For example, for ISO 32, and SAE 10W, we’re going to cover why it’s so efficient (and so on). Let’s take a closer look next.

Get the best made in USA synthetic compressor oil recommended for use in rotary screw, rotary vane, reciprocating and other compressor applications. Compatible with PAO, ester- and petroleum-based compressor oils. Not compatible with glycol- or silicone-based compressor oils.

Above are the available oils listed by grade. Improve compressor efficiency, control foam, wear, resist water contamination, heat and oxidation! The SIROCCO™ oil is recommended as a direct replacement for PAG compressor oils such as Sullair Sullube 32 and Ingersol-Rand SSR Ultra Coolant.

Synthetic Compressor Oil – ISO 32, SAE 10W

Amsoil Synthetic Compressor Oil – ISO 32, SAE 10W is specifically formulated to improve operational efficiency and performance. The advanced synthetic base oil protects against wear and maximizes efficiency, while its low-friction properties and exceptional oxidation resistance help prevent viscosity increase.

Viscosity increase can lead to inefficient operation and performance loss in compressors. This can cause increased strain on the system and potentially lead to costly repairs or replacements.

Synthetic Compressor Oil – ISO 46, SAE 20

Amsoil Synthetic Compressor Oil – ISO 46, SAE 20 is an ashless and high-flash point formulation that provides improved fire safety. This oil has very low carbon-forming tendencies which minimize the risk of ignition, reducing the potential for dangerous “hot spots”.

While this product cannot be considered non-flammable, it does give operators and users increased safety protection in comparison to other compressor oils. It is the perfect choice for those looking for reliable fire safety in a compressor oil.

Synthetic Compressor Oil – ISO 68, SAE 30

Amsoil Synthetic Compressor Oil – ISO 68, SAE 30 contains anti-foam additives for your compressor that help to:

Reduce heat
Oxidation
Decrease Wear

This helps to extend the life of the compressor and reduce maintenance costs. This allows your compressor to maintain optimal performance.

Synthetic Compressor Oil – ISO 100, SAE 30/40

AMSOIL Synthetic Compressor Oil – ISO 100, SAE 30/40 is formulated to resist water contamination and provide long-lasting protection for your compressor. This oil helps protect against rust and corrosion by separating quickly from any accumulated water that may have entered the system

The oil is hydrolytically stable, so it resists the formation of acids and can easily be drained for disposal and extended lubricant life. With this oil, you can rest assured that your compressor is well-protected against water contamination.

SIROCCO™ Compressor Oil – ISO-32/46

Amsoil SIROCCO™ Compressor Oil – ISO-32/46 is designed to keep your compressor running at peak performance for longer. It resists foaming and inhibits rust and oxidation, meaning it won’t break down due to exposure to moisture or other environmental factors.

This oil is specially formulated for use in rotary screw compressors, providing the highest levels of performance and extended drain capability. With its superior protection against breakdowns caused by high temperatures and moisture, Amsoil SIROCCO™ Compressor Oil – ISO-32/46 will ensure your compressor runs smoothly.

Let’s take a look at some related questions next.

What is the Best Air Compressor Oil?

Amsoil offers the best air compressor oil because it is specifically formulated to meet all the demands and requirements of air compressors. It contains

Highly refined base stocks
Special detergents
Rust inhibitors
Anti-wear agents
Oxidation inhibitors

This list above supports wear protection and improves system efficiency.

Does Amsoil ISO 32, SAE 10W Compressor Oil Minimize the Risk of Ignition?

Yes, Amsoil ISO 32, SAE 10W Compressor Oil helps to minimize the risk of ignition. It has been formulated with a combination of synthetic base oils and advanced additives that provide superior protection against wear, oxidation, and rust.

How Often Should I Change My Compressor Oil?

The frequency with which you need to change your compressor oil will depend on the type of air compressor you have and how often you use it. For example, if you have a small portable air compressor, you might only need to change the oil once a year. Alternatively, if you have a large industrial air compressor, you will need to change the oil more often.

Can I Use Any Oil in My Compressor?

No, you cannot use any oil in your air compressor – it must be specially designed for compressors. Using the wrong type of oil can damage your compressor and void your warranty. Be sure to check your owner’s manual before purchasing oil for your air compressor.
