What Kind of Oil Goes in a DeWalt Compressor?
It is extremely important to refer to your compressor manual before purchasing DeWalt oil for your DeWalt compressor. We have numerous DeWalt compressor manuals available on our brand page so please visit here first!
The manual will tell you what DeWalt oil is compatible with your air compressor, if you cannot locate your manual, please contact DeWalt directly or visit their website to download a manual for your compressor.

Alternative Compressor Oils Available on Amazon
A few alternatives to the DeWalt advised compressor oils are produced by Mobil. Again, it is very important to ensure the oil is compatible with your air compressor before putting it into the system, so please check first!
The first is the Mobil 101016 Rarus which is suitable for reciprocating air compressors whether they’re single or multistage. This oil lubricant boasts excellent water separability, protection against rust and corrosion, long life for extended oil drain and provides your compressor with very clean air valves.
The second is the Mobil 100870, boasting similar benefits as the previous oil but potential to work with reciprocating, rotary screw and rotary vane compressors.
How Much DeWalt Oil to Use in a DeWalt Compressor?
It’s quite a difficult task determining how much DeWalt oil a pump requires in a specific model without having the manual at hand.
If you’re finding it hard to locate your specific manual, you should contact DeWalt directly or search the internet for the specifications of your DeWalt compressor and its model to be able to find it!
I will now provide you some useful tips on how to check the DeWalt oil amount inside your compressor and then present a step by step guide on how you can go about changing it.
DeWalt Oil Sight Glass
The image below shows a sight glass with the DeWalt oil inside on a compressor pump. This will allow you to check the DeWalt oil level which should be approximately half way up the red dot.
DeWalt Oil Dipstick
In some cases you may need to check the DeWalt oil level by using the dipstick, if the pump doesn’t have a sight glass.
Take the dipstick out of the sump and give it a clean before putting it back in the sump and checking the DeWalt oil level via the markings.
Alternative Method for Checking DeWalt Oil
If you don’t have a sight glass or dip-stick on your DeWalt compressor then an alternative method is draining the DeWalt oil from the tank into a reservoir and judging the level from that.
How to Drain DeWalt Oil from the Sump
Locate your DeWalt oil plug drain and unscrew it – allowing you to drain the DeWalt oil into a reservoir, which can help you gauge how much DeWalt oil was in your compressor pump.
Note: Be careful not to get any spillages when draining the DeWalt oil. A useful idea may be laying something out on the floor below the compressor like dust sheets to avoid this and catch any spillages.
How to Change DeWalt Compressor Oil
Of course, changing the DeWalt oil on each model of DeWalt compressors can vary significantly. Before doing anything, check the model manual or contact DeWalt directly to find whether your compressor is definitely oil lubricated.
Changing DeWalt Compressor Oil Process
Follow the steps previously described for draining the DeWalt oil from the compressor into a reservoir, and then securely tighten the plug back into the bottom of the sump.
Now, add the replacement DeWalt oil you have at hand into the intake port at the top of the sump.
Given that the process can vary depending on the specific model of your DeWalt compressor, it is difficult to be any more specific than this.
You should add near to the same amount of DeWalt oil that you’ve removed, or gauge the level using the sight glass or dipstick if you have either.
Note: when filling the compressor with DeWalt oil, ensure you do not fill the air intake on the pump or overfill the sump.
The above methodology is simplified for ease into the following steps:
- Check the DeWalt compressor oil level
- Locate plug on compressor sump
- Drain the DeWalt oil
- Securely tighten sump plug
- Locate the DeWalt compressor oil intake port
- Replenish the compressor with the same amount of DeWalt oil as previously removed or judge it by using the dipstick or looking in the sight glass (do not overfill)
Without having access to every air compressor model manual, and assuming that the manual tells the reader what the DeWalt oil volume is, there is no way to be anything but vague when providing advice about changing DeWalt compressor oil and the level in which you must add.
