How Do I Dispose of My Old Oil and Oil Filters?

Changing the oil and oil filters on your compressor is one of the most common routine maintenance tasks to perform to keep your compressor running efficiently. After you remove your old oil and oil filter, you may find yourself wondering, โ€œWhere do I dispose of these?โ€, or โ€œCan I just throw them in the trash?โ€. Because oil is toxic and a pollutant, disposing of your old oil and filters is not as simple as just tossing them in the trash.

EPA regulations require all oil and oil filters from equipment, vehicles, etc. to be disposed of or recycled properly. The used oil can be recycled or refined into lower grades of lubricating oils or fuels. You can also choose to take your used oil to a local body shop or service station and they will recycle the oil for you. According to the EPA, used oil from one oil change is enough to contaminate 1,000,000 gallons of water. This is why the oil should not be disposed of in regular trash cans or dumped in the grass or on the side of the road.

Oil filters must also be disposed of properly since they contain, at the very least, trace amounts of used oil. To dispose of your used oil filters, you have 3 options: puncture & hot-drain the filter, crush the filter or take the filter by a body shop or local recycling facility that accepts used oil filters. To hot-drain the filter, carefully remove the filter from your unit while it is still warm (Use caution when hot-draining filter to avoid being burned. Protective equipment such as safety glasses and gloves should be worn to prevent injury). Then carefully puncture the end of the filter and set upside down for at least 12 hours to let the oil drain out into a container or pan. Once completely drained, you can recycle the empty can and the oil. You can also purchase a filter crusher that will crush your old oil filters, similar to drink cans, and they can then be recycled. If you do not want to handle the recycling process yourself, you can also take your old air filters to a local body shop or recycling center. 

Disposing of your oil and oil filters properly ensures less harm to the environment, and no fines for your business if you frequently need to dispose of oil related items.

Just like any other equipment, a compressed air installation also requires the necessary maintenance work during its entire lifespan. Even though maintenance costs are only about 5 to 10% of a machine's annual operating costs, failure to budget for maintenance can have potentially disastrous consequences.


The air dyer is one of the most ignored cooler in the system. A dirty condenser will cause water in the lines, or worse it will cause complete dryer failure.


Using nitrogen is not about fully replacing CO2, but it can reduce their consumption of CO2 by close to 70%. Using nitrogen is about sustainability. Creating your own nitrogen is easy and will reduce the use of a greenhouse gas, which is better for the environment. It will also save you money as early as month one adding that savings to your bottom line.
