How to Oil A Nitro Piston Air Gun? 4 Easy Steps!

It’s vital to look after your air gun if you want it to last long and perform well. Oiling or lubricating your air gun is one of the most critical things you can do. But it’s done to ensure that all internal components perform with little friction and wear. 

So, exactly how to oil a nitro piston air gun? 

Oiling a nitro gun is a relatively straightforward process. Start by detaching your piston and scrutinizing it. After that, clean all the parts. Once you’re done cleaning, you need to wash the piston of residue and lubricate it using motor oil. Finally, reassemble all the parts. 

Let’s take a look and see what you need to know about these topics to keep your air gun in top shape.

Things to Note Before Oiling Your Nitro Piston Air Gun

Every springer is a steel-based air-compressing mechanism. This is the key to understanding your springer’s lubricating requirements. As a result, there are 3 points to consider before you start your lubrication: 

  • Except for the barrel channel, your springer must be completely airtight.
  • Your springer is subjected to many loads, and its components are prone to mechanical abrasion.
  • It will erode if your springer comes into touch with water, acids, or humidity.

How to Oil A Nitro Piston Air Gun?

Oiling a nitro piston air gun may seem complicated at first. However, it’s nowhere near as twisted as zeroing a scope. 

The compression chamber and internal components of spring airguns should be lubricated using cotton cloth PCP and silicone oil. Follow through these steps to lubricate your gun correctly.

Step 1: Scrutinizing the Seal

The first thing that you need to do before oiling a nitro piston gun, is to scrutinize the seal. 

For that, take your piston to remove the piston’s seal. Then check the seal to examine if it’s cut or melted. 

If the seal is melted, you need to change it and place a new/fresh one. It’s because having a functioning seal is important

Sometimes your benjamin fails to hold air. This happens when your seal is broken. 

Once done, clean all the edges around the perimeter. 

Step 2: Cleaning the Piston

Now, clean your piston. To scrub the piston and the seal, take a cloth and clean it thoroughly with a solvent or cleaner. Here are our top picks for cleaners: 

After that, wipe it down with a solvent-soaked cloth if the seal material allows it. 

Now, wrap some microfiber cloth around the end of a long wooden stick. Use your cleaning rod for this. 

However, a stick might last longer. Plus you won’t face any blending issues. So, you can use that as well. 

After that, apply a few drops of solvent to the inside of the cylinder and clean it.

If you have a long enough cleaning rod, you can access the barrel through the cylinder and clean it. The barrel should also be given a solvent wash because the diesel effect can occur inside the barrel.

Step 3: Oiling the Piston

Now, let’s get into the main part. Oiling your piston requires patience and acute attention to detail. 

Start by rubbing one drop of full synthetic motor oil over the seal and piston front with your fingers. Here are our top choices when it comes to motor oils: 

Make sure to reach all the nooks and crannies of the piston air guns. 

Refrain from going overboard with the oil. Putting too much oil might do more harm than good. 

Step 4: Congregating the Gun 

Once you’re done oiling the piston, install the piston in the cylinder. Finally, reassemble your gun after going through the steps. 

This marks the completion of oiling your nitro piston air gun.   

3 Tips for Oiling Your Nitro Piston Air Gun

Now, that you know how to oil your nitro piston air gun, there are some additional tips that you need to follow. They are-

Tip 1: Stick to Petroleum-based Oil

The lubrication should be done with petroleum-based oils and greases. Metal parts should never be lubricated using silicone-based lubricants. 

Tip 2: Go with Tested Lubricants

Don’t be fooled by claims of Teflon coating, liquid Teflon, or “contains Teflon.” You’ll be fine if you stick to tested lubricants.

Tip 3: Don’t Use Organic Lubes

Organic (vegetable or animal fat-based) lubes should not be used. They disintegrate quickly and yield mild acids.


Do You Have to Refill Nitro Piston?

Yes, the rifle’s sealed nitro cylinder never has to be changed or refilled because it is a part of it. Instead of air or spring, the single pump compresses nitrogen like in most air guns. 

What Can You Use If You Don’t Have Gun Oil?

If you don’t have gun oil then you can use ATF or Mobil One synthetic for lubrication. Brake/carb cleaner works great for cleaning barrels, but you might want to pass if you don’t have excellent ventilation.

Can You Use Baby Oil on Guns?

If you want your gun to run, you really shouldn’t use baby oils on guns. Mineral oil is essentially what baby oil is, and it will respond negatively to temperature extremes. 


With that, we’ve reached the end of this segment. I hope by now you’re clear about how to oil a nitro piston gun.

As always, exercise caution when dealing with your gun. Try not to do anything unsafe or risky.

With that in mind, go ahead and put your gun through its paces!
