What factor influences how often compressor oil should be changed?

The frequency with which compressor oil should be changed is significantly influenced by the quality of the shop air. When the quality of air is poor, it may contain higher levels of contaminants, moisture, and particulates, which can degrade the oil more quickly and lead to increased wear on the compressor components. As a result, if the air quality is compromised, the oil will become less effective at lubricating and protecting the compressor, necessitating more frequent oil changes to maintain optimal performance.

Other factors do play roles in maintenance schedules, but they often do not have as direct an impact on the need for oil changes as the quality of the air being compressed. For instance, while the type of compressor can dictate certain maintenance requirements, and the frequency of air use can put more strain on the oil, the immediate consequences of poor air quality have a faster effect on oil degradation and the overall health of the compressor system.

Therefore, monitoring and ensuring good air quality is crucial for establishing a proper oil change schedule to prolong the life of the compressor and maintain its efficiency.
