Buying Guide for the Best Air Compressor Oils

In order to find the best synthetic air compressor oil, you have to go through this section to see what factors you need to tick off.

Oil Viscosity or Weight

The SAE, weight, or viscosity of every oil out there isn’t the same. When it comes to synthetic oil, weight plays an important role. The functionality of your oil compressor depends hugely on how much oil you add.

If your oil has the perfect firmness, then there is a bigger chance of your machine running more smoothly. If the viscosity is high, then oil will be thick and if it is low, it will be more runny and watery.

Mostly, the weight of 20 and 30 are considered to be ideal for any air compressor application.
But in our suggestion, if you have a heavy application, then you should go for the 30 weight oil. For lighter applications, it would be better if you opt for the 20 weight oil.

Choose a 40 and 50 weight oil when the temperature is very high.

Temperature Range

Another important aspect of the buying guide is the range of temperature.

If your oil does not have an accurate temperature, then in no way would your oil work, even if it has the perfect viscosity. Usually, you will find the temperature range written in the bottle.

People who live in places with high temperatures and low temperatures should buy items that can keep the ideal viscosity in the expected range of temperature.

If your compressor’s engine produces a good amount of heat, then you must pick a high-temperature suited oil if you want your machine to perform well and more efficiently.


It is important to know what are the additives that are in your air compressor oil. There are additives that can benefit your machine in a way. So, you should choose accordingly.

Brand of Oil

There is no doubt that you should for sure get a good brand of oil. The quality has to be high if you want your machine to be up and running for a good period of time.

A detergent air compressor oil would do no good to your machine. Be certain that the oil you buy is free of detergent. The quality of the oil should also meet with the air compressor.

Frequency of Oil Changes

You need to change your synthetic compressor oil regularly. The manual of the compressor should give you the proper directions and instructions on when to change air compressor oil.

Ones using a rotary model should get a change done after every 7,000 to 8,000 hours. The DIY ones should be changed once every year. For a reciprocating one, you have to do it once every 2-3 months.

But if you use the air compressor quite constantly, then you would need more oil change.
While adding a synthetic compressor oil, be sure to use an oil filter.

How Much Compressor Oil to Use?

There are times where you would be required to put in 3 oz of air compressor oil to keep a machine functioning properly. In some cases, such as for industrial purposes, 100 oz of oil is required to run the components.

If you follow this buying guide, then you will find the best synthetic air compressor oil according to your requirements.
