How often does the air compressor oil change?

The replacement cycle of air compressor oil is not fixed. It is affected by many factors, including oil type, model, working environment and frequency of use. Here are some general guidelines:

mineral oil: It is usually recommended to replace it after 3 to 4 months of use. It is also recommended that mineral lubricants be replaced in 2000 to 3000 hours.

Semi-synthetic oil: It is generally replaced after 6 to 8 months of use, or it is recommended to replace it in 4000 to 6000 hours.

Fully synthetic engine oil: It is recommended to replace it after 10 to 11 months of use, and it is also recommended to replace it in 6000 to 8000 hours.

For screw air compressors, especially new screw air compressors, the lubricating oil should be replaced after 500 hours of first operation, and then every 2000 to 4500 hours, depending on the operating environment and the specific conditions of the machine. Sometimes, although the cumulative operating time does not reach the recommended number of hours, if the time without changing the oil has reached a certain length of time (such as half a year), the lubricating oil must also be replaced.

In addition, the replacement of air compressor oil is also recommended according to the actual oil test results to determine. Regular oil inspection can find the deterioration of the oil in time, so as to determine whether it needs to be replaced.

In general, in order to ensure the normal operation of the air compressor and extend its service life, the air compressor oil should be checked and replaced regularly. When choosing air compressor oil, you should also pay attention to choosing the appropriate type of lubricating oil and avoid mixing different brands or types of oil.
