How often do I change the oil of the air compressor

The replacement cycle of air compressor oil varies depending on the type of oil used, the use environment and operating time of the air compressor. The following are general guidance and suggestions:

Determine the replacement cycle according to the type of oil

  1. Minite oil:
    • Replacement cycle: It is recommended to replace it every 3 to 4 months, or every 2,000 to 3,000 hours of operation.
  2. Semi-synthetic oil:
    • Replacement cycle: It is recommended to replace it every 6 to 8 months, or every 4,000 to 6,000 hours of operation.
  3. fully synthetic engine oil:
    • Replacement cycle: It is recommended to replace it every 10 to 11 months, or every 6,000 to 8,000 hours of operation.

Adjust the replacement cycle according to the use environment and operating time of the air compressor

  1. Newly purchased air compressor:
    • First replacement: Newly purchased air compressor must be replaced after running for 500 hours.
    • Subsequent replacement: After that, replace it every 4,000 hours according to the normal oil change cycle.
  2. Special working environment:
    • Many air impurities: If there are more air impurities in the air compressor, the engine oil should be replaced in advance.
    • Contains corrosive substances: When corrosive substances are contained in the air, the replacement cycle of the engine oil should be appropriately shortened.
    • The ambient temperature of the computer room is high: When the ambient temperature of the compressor room is high, the replacement cycle of the engine oil should be appropriately shortened.
    • Contains a lot of dust: When the air contains a lot of dust, the replacement cycle of the engine oil should also be appropriately shortened.

Precautions for replacing air compressor oil

  1. Select the right engine oil: Choose the appropriate engine oil type and specifications according to the use environment and requirements of the air compressor.
  2. Confirm the quality of the engine oil regularly: Check the performance indicators of the engine oil color, viscosity and other performance indicators. If abnormalities are found, replace them in time.
  3. Full cleaning when changing the engine oil: When changing the engine oil, the oil filter, oil pan and other components should be thoroughly cleaned to avoid the residue of old engine oil contamination on the new engine oil.
  4. Follow the manufacturer’s advice: Air compressors of different brands and models may have specific requirements for the oil replacement cycle, and it is recommended to follow the manufacturer’s advice.

Summary

The replacement cycle of air compressor oil is a result of comprehensive consideration of multiple factors. In order to ensure the normal operation of the air compressor and extend its service life, it is recommended to reasonably formulate a replacement cycle based on factors such as the type of oil used, the use environment and operating time of the air compressor, and regularly check the quality of the oil, and change the oil in a timely manner. At the same time, following the manufacturer’s recommendations is also an important factor in ensuring the normal operation of the air compressor and extending its service life.
