Typically, with a rotary screw compressor, you should change the oil every 7000 to 8000 hours that it has been used. For a reciprocating air compressor, you should change the oil every 3 months, ideally. It is important, however, that you change the oil at least once in a year.



Using the right air compressor oil for your compressor is very important. This is true for both rotary screw air compressors and reciprocating compressors. You can't just use your cars oil or hydraulic oil!!!!! Compressor oil has a few important functions:

  • It removes heat from the compression

  • It works as a sealing to prevent air leakage.

  • It lubricates all moving parts

  • It's used to cool important parts of the compressor element.

Air compressor oil is specifically designed to do the above jobs well. If you use oil from your car, your compressor WILL DIE!!

Compressors (and the oil) can get very hot.. normal maximum outlet temperature of a rotary screw compressor element is set at 120 degrees Celsius (if it gets hotter than this, your screw compressor will shut down).

If you would operate your compressor on a too high temperature for a too long time, the oil will form a thin layer on the entire inside of your compressor (piping, compressor element, oil cooler). When this happens to your oil-cooler, it won't be able to cool the oil as effectively as it used to. 


What Type Of Oil Are You Currently Using: Knowing what type or brand of oil you are currently using with your air compressor is very CRUCIAL to the performance of your compressor. Compressors have a long life time and over that lifetime you may have filled it with different brands or types of oil. Compatibility is key and knowing what type of oil is currently in the unit helps guarantee product compatibility. Remember the old Pennzoil add on TV "PAY ME NOW OR PAY ME LATER"

An ounce of prevention will go a long way in maintaining the health of your air compressor. We recommend changing your oil at least 2 times a year on most piston air compressors. Our typical visit to your location and the service that we perform on your compressor looks something like this.

1. check the belts and hoses and adjust or replace if necessary.

2. change out the air filter.

3. drain and fill the pump with Teresstic ISO 100 high grade compressor oil.

A typical visit to you location and the service that we perform on your rotary screw compressor looks something like this:

1. check belts and hoses.

2. change out the separator.

3. change out the oil filter.

4. blow out the radiator.

5. check for any codes and reset codes if necessary.

6. drain and fill the rotary screw compressor with 8000 hour synthetic high grade compressor oil.
