Not sure which gas will make your airsoft gun perform best without damaging its internal components? Your choice of fuel affects everything from muzzle velocity to accuracy – especially in the varied Norwegian climate. Here's everything you need to know.
Which gas is best? A quick overview
To make it easy for you, we have put together an overview of the most common fuel types and when you should use them:
| Type | Pressure (PSI) | Best for... | Benefits |
|---|---|---|---|
| Green gas | ~115 | Standard pistols | Contains silicone oil for lubrication |
| Red/Black gas | ~130-150 | Metal guns & rifles | Better performance in low temperatures |
| CO2 (12g) | ~800+ | Hard-firing weapons | Stable pressure regardless of temperature |
1. Green gas: The faithful classic
For most players, the Green gas the default choice. Most modern airsoft guns are designed to run at this pressure. The low pressure causes less wear on internal components and is gentle on seals.
We often recommend Ultrair Power Gas from ASG for its reliability and consistent pressure. If you want a gas with pre-added silicone oil for automatic lubrication during use, Nuprol 2.0 (Green) an excellent alternative.
Expert tip: Look for gas cylinders marked with "Silicone Added." This means you won't have to lubricate your seals as often, as the gas helps maintain them while you shoot.
2. When should you upgrade to Red or Black gas?
When the temperature drops below 10°C in Norway, you will notice that the green gas loses pressure. This is called the cool-down effect. Red gas has a higher pressure which compensates for the cold and ensures that the weapon charges properly.
For the colder days, Nuprol 3.0 Red Gas or the extra powerful Nuprol 4.0 Black Gas be good options, provided your weapon has a solid metal slide.
- Warning: Never use black or red gas on guns with plastic slides, as the high pressure can cause the material to crack.
3. CO2: For those who want the most power and recoil
One 12g CO2 cartridge gives a stronger recoil (blowback) and is almost unaffected by cold. This is perfect for those of you who play outdoors year-round in Norway, as CO2 remains stable all the way down to freezing point.
Need a refill? We have a large selection of CO2 cartridges in multipacks which ensures you never run out in the middle of a game.
Since CO2 is a "dry" gas, it is critical that you apply a drop of silicone oil to the tip of each cartridge before inserting it into the magazine. This will keep your O-rings tight and prevent leaks.
Summary – What should I choose?
If you are a beginner and have a regular gas gun, go for Green gas. It is safest for the weapon and easiest to use. Are you going to play in sub-zero temperatures? Then a CO2 model your best friend.
