How Often Does the Oil Need Changed in Your Air Compressor?

An air compressor is a convenient tool to use for multiple projects. It needs to stay in tip-top condition to work properly. Maintaining your air compressor will allow it to last longer and prevent costly repairs or replacements. One of the essential maintenance requirements to help your air compressor last is changing the oil. Read on to determine how often you should complete an air compressor oil change.

The Importance of Changing the Oil in Your Air Compressor

Oil is the bloodline of your air compressor, and it is responsible for sealing and cooling during compression. Proper lubrication for air compressors prevents the compressor from overheating and shutting down. The oil also prevents the individual components of your compressor from wearing down or breaking prematurely.

How Often Should the Compressor Oil Be Changed?

The type of compressor you own plays a critical component in how often you need to change the oil. Not all compressors need to be changed at the same interval. The owner’s manual is the best source to determine when you should change it. 

You may be unable to find your owner’s manual, and there are some basic rules to follow. They are:

  • Rotary Screw Compressors need an oil change every 1-2,000 service hours.
  • Reciprocating Air Compressors need an oil change every three months.

You’ll find more detailed information in your owner’s manual, but you should always change the oil at least once per year. 

What Type of Oil Should be Used?

It’s always best to follow the manufacturer’s instructions in the owner’s manual — it’s the best quality for the compressor, and it also ensures you comply with the manufacturer’s warranty. If you cannot find the manual, use 68 or 100-grade hydraulic oil.

Compressor oil is a better choice than motor oil. It’s explicitly designed for compressors, and it’s more likely to give it a longer lifespan. You can use standard oil for compressors that are used for regular use. It costs less than more expensive, synthetic oils. 

Heavy-duty compressors should use synthetic oil. Synthetic oil will prevent the compressor from overheating, and it’s also ideal for cold weather. Compressors will run quieter and smoother with synthetic oil.

Where Can You Buy Compressor Oil?

You should buy compressor oil from an authorized distributor. You can always ask a professional or your friends if you are unsure where to buy the oil.

You can also purchase compressor oil online from trusted sources like Amazon. It’s best to read the reviews to ensure the product is of high quality. You can always check with a professional before purchasing to make sure.

Oil changes are simple maintenance that will keep your oil compressor running effectively for a long time. They will prevent costly breakdowns or replacements.
