Magnum Airpower's HIGH-PERFORMANCE AIRGUN OIL
is non-toxic and provides the highest level of wear and corrosion protection in the industry. It works exceptionally well in all temperature ranges staying fluid at -40° F and maintaining the optimal SAE 30 viscosity at the highest possible environmental temps. It has an operating range of -40° F to 500° F  with a flash point of 450° F. This oil is recommended for all variable pump and CO2 models. It also works exceptionally well for break barrel models that require petroleum-based oil.
It should not be used in the compression chambers of PCP, HPA, dual-fuel or break barrel models that require silicone oil. For assembly and maintenance of such components use our
HIGH-PERFORMANCE SILICONE OIL.
VARIABLE PUMP :
These models should be assembled with oil to lube all the seals and moving parts. Add a drop of oil directly into the pump chamber every couple hundred shots. You can do this more often if the piston isn't working smooth or produces inconsistent performance. If you accidentally over-oil you can fire the gun with the barrel pointed straight up, unloaded and safely away from you. In that position excess oil settles near the valve stem and blows out through the barrel. To prevent oil-lock, only use one pump for each shot until excess oil is cleared from the pump chamber and valve. A drop of oil should be applied to all pivot points of the pump lever and one at the back of the piston seal. This will lubricate the contact points of the pump assembly. The owners manual should indicate other model-specific lubrication points.
CO2 :
Like the pump models above, these should be assembled using oil to lube all the seals and moving parts.
CARTRIDGE POWERED:
For models with a piercing cap or rod that threads into the front of the gas tube, the threads should be oiled occasionally to keep them working smooth and prevent rust. A drop of oil should be placed on the tip of each cartridge before installation. For 22XX this prevents the piercing pin from getting stuck in the cartridge which keeps the cartridge stuck in the tube. It also lubricates the valve, ports and barrel to preserve performance and reduce corrosion. After installing a cartridge the gun needs to be fired once (unloaded) to pierce it. This is not a malfunction, it's how they are designed to operate. Other types of CO2 guns will pierce the cartridge automatically during installation.
BULK-FILL :
A drop of oil should be placed in the fill nipple before each fill.
This is not safe for dual-fuel PCP models. Dieseling could occur during a rapid fill from a high-pressure (HPA) air tank. Use our
High Performance Silicone Oil
for Dual-fuel models.
AIRGUN OIL MYTHS
It's a myth that petroleum oil is harmful or unsafe to use for airguns.
This stems from the common misconception that petroleum oil and distillates are the same thing. They're not, oil is what's left after the distillates are removed from crude oil. Petroleum distillates are not safe for use in airguns for a variety of reasons.
Some petroleum oils also contain distillates and those are also not safe.
This subject is even more confusing to many because some distillates are commonly referred to as oil. The most common examples are heating oil and penetrating oil which are both petroleum distillates. The oil that's safe for airguns is called mineral oil also known as heavy oil. Mineral oil is non-toxic and non-flammable but it's combustible at very high temperatures. It protects against wear and corrosion better than silicone or natural oils, will not harden and doesn't become rancid. This is why all engine oils, including synthetics, are mineral oils. Many believe synthetic engine oils are made from non-petroleum substances like silicone, this is not true. Synthetic engine oils are made from mineral oil. Silicone oils are synthetic also but aren't used for engines due to their poor lubricating and anti-wear characteristics. Engine oils, natural or synthetic, will not hurt the seals in your gun. Modern airgun seals are made of materials like Nitrile and urethane which are engineered for use with petroleum oils. We've been using mineral oil (engine oil) in airguns for many years and have never seen a Nitrile or urethane o-ring swell or dissolve.
This oil is not safe for PCP & HPA due to the risk of rapid compression autoignition (dieseling) so the silicone oil we have listed is recommended for those applications. Silicone oil will swell and soften Viton o-rings so Nitrile or urethane should be used.
It's a myth that engine oil is toxic.
Most are not. Some do contain potentially harmful additives, these will say so on the container and should be avoided. Used engine oil is typically more toxic, combustible and can even become flammable, this is due to fuel contamination and engine wear.
It's a myth you shouldn't use detergent oil for an airgun.
It actually works better than non-detergent. The "detergents" are metallic salts that reduce wear and corrosion. They also help keep particles suspended in the oil so they can be removed by a filter or exit machinery as they work their way through. Moisture is absorbed and passed through without negatively affecting the lubricating properties of the oil. Emulsification is what many fear with detergent oils, this doesn't happen to a significant degree in an airgun and wouldn't be an issue if it did, it would simply mean more moisture was present and being worked out of the gun. Moisture content in emulsified oil does not affect it's lubricating and wear reduction properties.
Crosman Pellgunoil (re-packaged Monolec GFS 8430)
is SAE 30 engine oil with a high level of detergency. Because it's single-viscosity it gets significantly thicker in cold temps.
Our HIGH-PERFORMANCE AIRGUN OIL
is full synthetic and multi-weight. It flows freely at very cold temps and maintains it's viscosity at very hot temps. It has the highest level of anti-wear and anti-corrosion additives of any oil on the market.​
