Buying Guide: Best Air Compressor Oil

There are a few aspects more important than others when purchasing air compressor oil. Compare these features within your budget range before you select the best air compressor oil for you.

Viscosity

It’s a measurement of your air compressor oil’s thickness. Which one do you think is better? The oil with higher viscosity or the one with the lower one?

There are generally two types of oils professionals suggest.  SAE20 and SAE30. The first one is comparatively thinner than the latter one.

If you live somewhere cold, SAE20 will be better suited for your compressor. In comparison, for warmer areas, SAE30 is a much better option. You must choose the oil of suitable viscosity, or you’ll end up damaging your air compressor components. 

Temperature Range

Even when the viscosity is compatible with your compressor, sometimes the combination goes wrong because of the temperature range. Areas with temperatures above 120 degrees F or lower than the freezing point can become useless to your machine.

Check the oil specifications and match them with your living area before you can buy the compressor. One other thing to remember is, your compressor also produces heat when running. So, consider it too before choosing the oil.

Additives

Many times, additives in an oil can be temporarily helpful to your compressor but damage it in the long run. Look what additives are used in the compressor oil. Make sure there aren’t any detergent additives in the oil.

Some additives, however, can benefit the compressor both instantly and in the long run. These are necessary to prevent rust and corrosion that can occur due to the friction between the inner components of your compressor.

Synthetic And Standard Oil

Both these oils are compatible with most competitors. So, which one should you go for?

Synthetic oils are more refined. So, you won’t need to change the oil very often. However, these oils come expensive.

Standard oils, on the other hand, will lubricate your compressor but require more frequent oil changing. But, they’re comparatively cheaper.

So, if you run a compressor for your home and do not frequently use it, we will recommend you go for a standard oil compressor. If you use your compressor for industrial necessities, you should go for synthetic oil.

Do All Compressors Need Oil?

There are both oil-lubricated and oil-less compressors. However, oil-less compressors aren’t quite oil-less. Instead, they’re coated initially and don’t require lubrication again.

Not being able to lubricate a compressor means you won’t be able to recover it from wearing. That is why oil-less compressors come with shorter life compared to oil-lubricated ones.

As for an oil-lubricated compressor, with proper care, it can last a long time.

What Air Compressor Oil Does?

Oil-lubricated air compressors require oil as a mandatory maintenance measure. Many people prefer oil-less compressors because they don’t want to go through with maintenance. However, oil-lubricated compressors are more potent than oil-less ones.

Oiling your air compressor allows you to get the best out of your machine. Some of the high-lighted benefits you can get are-

Low Noise Operation

Even the powerful compressors can run quietly with the help of oil. The larger the machine, the louder it’ll sound. Oil can reduce the noise level to a tolerable level.

Smooth Operation

Oil lubricates the metal components of an air compressor. That means less friction and less heat production inside the engine. The cooler the unit runs, the more efficiently it can function. 

Durability

Proper oil lubrication ensures extended lifespan for your air compressor. When you fulfill your air compressor’s necessity, it runs better and longer.

Oil also prevents rusting, corrosion, carbon build-up, etc., to keep the machine going with its best capacity.

How To Change Air Compressor Oil?

Changing your compressor oil is a pretty straightforward job to do. However, many people don’t know how to do it. A little tip, check the manual because this method can differ from one air compressor to another.

  • Make sure your compressor isn’t on. Unplug it from the power source, even if the switch is off.
  • Take a pan, bottle, or container where you’ll hold the old oil.
  • Locate the draining valve. If you can’t find it, check the manual. It’ll most likely be on the lower side of the compressor.
  • Place the container beneath the valve and open it. Let the oil pour into the container.
  • It can take some time to become empty. If it’s possible, angle your compressor a bit to let the remaining oil out.
  • Once it’s empty, close the valve. Make sure you tighten the valve so that oil won’t drip out.
  • There’ll be an oil cap to insert oil into the compressor. The method can vary depending on the compressor. It’s best to stick to the manual for this one.
  • Use a nozzle or funnel to insert oil into the compressor. Keep monitoring the oil indicator to ensure that you don’t overfill it.
  • Close the cap, store your oil container in a secure place.
  • Dispose of your old well using the right way. Or, you can ask the local store if they take used oil.

Air Compressor Oil Substitutes

It’s always better to go with an air compressor oil for your machine. However, if you find yourself in a situation where you need a substitute, you can look for one of the following.

Hydraulic Oil

Hydraulic oil comes with a few features, making it suitable for compressors. In cold temperatures, it features lower viscosity. Low viscosity in cold weather means the oil can move freely through the components.

That is why hydraulic oil is a decent alternative to air compressor oil in cold temperatures. Besides, it doesn’t oxidate, making it suitable to prevent the compressor from rusting.

Automatic Transmission Fluid

Mainly used for cars, automatic transmission fluid can also be put into air compressors. There are a few perks of using this lubricant.  It can reduce tear and wear and tear, for starters. Besides, it makes the components cooler when the compressor generates heat.

It also resists breakdowns and ensures that the compressor is working efficiently. Note that most ATFs won’t work on compressors.

Motor oil

You can only use motor oils that feature a non-detergent substance. Motor oils with detergents can help your compressor engine temporarily but end up damaging the unit by initiating carbon deposits.

These alternatives are only suggested as a temporary solution. Using these oils for a long time can damage your compressor as they’re not made explicitly for compressors. If you don’t wish to spend much money on oil, there are cheap air compressor oils with decent features that you can go for.

Cautions To Use Air Compressor Oil

  • Prioritize the compatibility between the compressor and the oil. If the oil does not suit your compressor, you’ll only end up wasting your time and money.
  • If you rarely use your compressor, don’t go for expensive synthetic oil. Instead, buy a standard oil for your compressor.
  • While changing the oil, make sure you don’t stain the surface. Even though you’ll use a container, keep your compressor on something that won’t get ruined by oil stains.
  • If your compressor isn’t functioning smoothly even after lubricating it, chances are, something is wrong. Consult a local professional for help.
  • If you don’t understand how to choose, use, and change compressor oil, ask someone for help.
  • Always keep your air compressor in check. Look for leaks and get them repaired if there are any.
  • Store your compressor oil as it says on the instruction manual. Don’t ignore the manual because some oil can evaporate if not stored properly.
