An air compressor is a machine pressuring air to power tools and inflates tires. The compressor has an oil reservoir that lubricates the machine’s moving parts. If there is oil in the air tank, it means that the compressor is leaking oil, and this is not a good thing.
Excess oil will build up in the compressor tank, and eventually, it will seep out. The oil can find its way into the airlines or into the pump itself. It is not a good thing because oil is not compressible like air.
If you notice oil in your air compressor tank, you should take it to a mechanic to have it fixed. In the meantime, do not use the compressor until it has been repaired.
Let’s get more in-depth about why having oil in the air compressor tank is the problem and how to prevent it.

Why Is There Oil In My Air Compressor Tank
If you’ve ever found oil in your air compressor tank, you’re probably wondering why it’s there and what you can do about it. Here’s a look at the most common causes of oil in an air compressor tank and how to fix them.
1. Leaky Piston Seal
A leaky piston seal is one of the most common reasons for oil in an air compressor tank. If the piston seal is damaged or worn, it can allow oil to escape from the crankcase and mix with the compressed air in the tank. You can usually fix this problem by replacing the piston seal.
2. Bad Check Valve
Another common cause of oil in an air compressor tank is a bad check valve. The check valve prevents air from flowing back into the crankcase, but if it’s damaged or defective, it can allow oil to enter the tank along with the compressed air. You can usually fix this problem by replacing the check valve.
3. Bad Air Filter
A bad air filter is one of the most common causes of a dirty air compressor tank. The air filter is responsible for trapping harmful contaminants before they can enter the tank. However, if the filter becomes clogged, it will no longer be able to do its job properly. As a result, contaminants will build up in the tank, eventually causing damage to the compressor.
4. Check hoses and fittings
One possibility is that the oil is coming from the hoses or fittings. It is usually caused by a loose connection or a crack in the hose. Inspect all of the hoses and fittings on your compressor to see if any are loose or damaged. If you find a problem, tighten the connection or replace the hose.
If you’re still seeing oil in the tank, it’s possible that there’s a leak somewhere in the system. If you have a small leak you can’t locate, your best bet is to take the tank off the compressor and use a pressure washer to spray it down. This way, you’ll see exactly where any leaks are coming from.
Why having oil in the air compressor tank is a problem
Oil in the air tank can cause a number of problems.
- It can cause the compressor to overheat.
- It can contaminate the air that is being compressed.
- It can damage the tools that are being powered by the compressor.
- It can cause damage to the compressor, reduce efficiency and shorten compressor life.
How to prevent oil from getting into the air compressor tank
If you find oil in your air compressor tank, it is important to take action to prevent further contamination. You can do several things to prevent oil from getting into the air compressor tank.
- Ensure that the compressor is properly installed. Oil can seep into the air tank if the unit is not level.
- Perform regular maintenance on the compressor. It includes checking and changing the oil as needed.
- Use only high-quality lubricants in the compressor.
- Avoid using the compressor in dusty or dirty environments.
These simple steps prevent oil from getting into your air compressor tank and keep your unit running smoothly for years to come.
Conclusion
Air compressors work by compressing air. This process creates heat, and the heat causes the oil to break down and mix with the compressed air. Over time, this mixture will begin to gum up and clog the system. To prevent this from happening, manufacturers add a small amount of oil to the air compressor to lubricate the moving parts and help cool them down.
So, if you find oil in your air compressor tank, don’t worry there are many reasons why this can happen, and you get the answer to how to prevent it in this article. If it is difficult for you, then contact professionals of Air Compressor.
