Gun Oil Buyer’s Guide

Aside from a good cleaning, lubrication is the biggest part of good gun maintenance. Finding the best gun oil for your firearm may seem easy, just choose a product with a high rating and hit that buy now button. But the truth is, there is a shocking amount of low-quality products currently on the market. Many of the best gun lubricants that you’ll come across are very heavy. A thicker oil doesn’t make it better. A lubricant that’s relatively thin should still be used sparingly.

In terms of performance, most lubricants will work the same, just some are better than others. When it comes to low quality lubricants, these are the products that often fail in terms of protecting a weapon against corrosion and must be reapplied often.

This buying guide on shopping for the best gun oils will go over how to choose the right oil for your firearm, the different application methods available, and how to find a product that won’t let you down, and one that will keep your firearm working smoothly AND protect it from corrosion.

The Importance of Keeping Firearms Lubricated

gun and cleaning accessories

As a gun owner, you already know the main reason lubrication is needed is to reduce friction between any moving parts. When you lubricate a weapon using the best gun lubricant, it reduces the friction coefficient between metal on metal components, providing a smoother operation, while helping to minimize wear. A firearm will use one or two types of lube: oil or grease. The type of lubricant you use will depend on the type of firearms you have. Always follow a manufacturer’s recommendations in terms of what type of lube will work the best for a specific firearm.

Types of Gun Oil

Lubricating firearms is one of the most important things you can do for routine gun maintenance. While it’s not exactly difficult to do, it can take a little practice before you learn how to apply the right amount. Keeping a weapon lubricated is so important because it ensures your firearm is able to perform at its highest level, while also protecting a firearm from wear and tear.

To accomplish this, the moving parts in a firearm must not directly rub against one another.

A thin layer of the best gun oils will grease the inner workings of a gun, allowing them to function properly, using minimal friction. This helps to significantly reduce wear and tear. It will also keep your gun working at the optimal level of performance and can extend the gun’s lifespan.

Anti-Wear/Extreme Pressure

When you’re shopping for gun oils, you’ll come across the term anti-wear/extreme pressure, frequently. A good oil will come with plenty of these additives, which can help keep your gun in top condition. These additives are mixed with straight oil to add additional properties and to thicken the lubricant itself. There is a wide range of different mixtures to choose from, each of which is designed for particular needs. In fact, there are literally hundreds of different compound mixtures that are used to give a lubricant the desired thickness level, in addition to other special properties.


Clean, lube, and protect products, or CLP for short, is considered an all in one product with compounds that work with each other to lubricate and clean a firearm. Some people recommend avoiding them since these products are made with chemicals that have to remain in the same can together for several years at a time. This means that the manufacturer must use a weaker cleaning solvent and a lighter oil. These products also don’t have a reputation for working for a long time like dedicated oils. When it comes to dissolving leading, copper fouling, or powder residue, these CLP products can’t do much. Some people recommend purchasing a dedicated gun cleaning solvent and a dedicated oil for a better performance and longer acting protection. However, other people argue that many of the top CLPs have come a long way and offer protection and cleaning power that’s comparable to a dedicated product. In the end, it can be a matter of personal preference.

Other Important Features

Choosing the right lubricant can be a matter of personal preference, since some lubes can be easier to apply than others. Additionally, you’ll find that some need to be reapplied more often.

Each type of firearm will have its own lubrication needs, depending on their function and design. The best gun oils can be used after a bore cleaning to lubricate every surface and keep your firearm working smoothly and firing efficiently.

Using a type of catch-all lube will not meet a firearm’s operational needs. Because of this, it’s important that you apply the right type of lubricant in the correct areas, as recommended by the manufacturer.

Application Methods

These days, a gun owner can choose from three to four different application methods. Some are easier and less messy to use than others. All types are designed to reach every part of a gun for fast and efficient lubrication.


Some people find that sprays are the easiest application method to use. Sprays  are pressurized cans of oil that can give you more control over where the oil goes and how much you want to use. However, spray oil is not recommended if you want to apply oil to the inner parts of a firearm.

Needle Applicators

If you’re looking for the most precise application method, then make sure you purchase a lubricant with a needle applicator. Oil that comes equipped with a needle applicator is designed for precision application. The long needle-like tool will allow you to apply oil exactly where you want it, and nowhere else.


Wipes are pre-soaked in oil, so all you have to do is take a wipe and run it over the surface of different parts of a gun. This allows for even application of the lubricant, but wipes can be difficult to use in hard to access areas. Wipes can also be one of the best things to bring with you in the field, if you need a fast, efficient way to lubricate your gun.


Some products will not come with any type of applicator, spout, or tool that will aid you in applying in the oil. Most gun enthusiasts will just use a clean cloth and dip it in the oil to apply it. This method may not be the best choice for the beginner, since it can be very easy to overapply a product.

Grease has a higher viscosity than oil. Lower viscosity means that it offers little impedance on moving parts and flows easily. Oil is usually the go-to lubricant for use between components that have a close operational tolerance, such as firing pins, slides, bolt internals, and fine trigger assemblies.

With its higher viscosity, grease can stick to a metal part longer than oil, so it offers a type of self-dispersing lubing function.

The majority of seasoned gun owners will consider an oil’s viscosity when shopping for a good product. A product should have a high viscosity index if you’re looking for an oil to use on a modern firearm. Viscosity refers to how thick a gun oil is. Because of the different types of additives used in gun oil, the oil can be thick like syrup, runny like water, or somewhere in between. The best viscosity is debatable. Most new gun owners believe that a thicker oil is the better choice. However, most parts of a weapon require a product with an oil-like consistency, not a thick grease-like consistency. Most of the parts of a firearm that need oil will benefit more from using a thinner oil.

Rust Prevention

When you’re shopping online, make sure you pay close attention to a lubricant’s reputation for keeping rust at bay. Rust is one of those things that can be a death sentence for a firearm. Depending on whether you’re oiling your gun before you store it, or you plan on using your firearm often, the type of oil that will work the best can vary. Firearms that are kept in pristine condition, with frequent gun cleaning will fire properly each time they’re used. If you live in a humid environment, rust will be a major concern, so you’ll want to focus on a product that contains additives that are specifically designed for rust prevention.

If the city you live in experiences harsh winters, then you’ll need an oil that’s designed specifically for those conditions.

Temperature Control

Using a type of non toxic synthetic oil can result in improved heat dissipation and temperature control. This can include both high and low temperature performance. Most types of synthetic oils feature colder pouring points. Many people claim this results in a faster lubricating process. Additionally, this allows a gun to perform better in colder temperatures. Synthetics have a higher viscosity index that allows for more consistent viscosity. All of this works to make a gun function in extreme conditions.


Some oils are thinner than others. If you live in a colder climate, one that includes freezing temperatures and plenty of snow, make sure you choose an oil that’s thinner, since it tends to flow better in colder conditions.

In a hotter climate, you’ll want to go with an oil that’s thicker, so you don’t have to worry about the oil running and being a magnet for dirt.

Gun Grease or Oil?

The biggest difference between grease and oil is the consistency. The best gun oil is much thinner, while grease is thicker and contains a type of sediment that can help reduce friction. You can find oil available in a variety of consistencies and weights and it’s used for parts that need protection against rust and oxygen.

Oil is used for components that reciprocate and rotate. Grease is meant for parts that slide. For example, the slide rails on a semi-auto pistol should be greased. These parts must slide without binding, with friction kept at a minimum. While grease can protect the surface of a firearm from rust, oil is a much better option. Oil doesn’t hold onto grim and dust and isn’t quite as gooey.

Gun Oils Versus Gun Solvents

People who are new to gun ownership may not know the difference between oil and gun solvents, but they actually have two very different jobs. Gun solvents are designed to clean dirty firearms, and can be used as a bore cleaner  to improve a firearm’s shooting accuracy and overall performance. Solvents are something all gun owners should use since it can get rid of fouling, dirt, sand, and grim. Cleaning your firearm with solvents ensures that your guns will fire predictably. Solvents are definitely an essential part of firearm maintenance. People who are shopping for a new lubricant for their firearm should also look for a good gun solvent. The solvent should be used prior to lubrication. After you’ve used a gun solvent, you can apply the lubricant.

Mineral Oil- A Non Toxic Option

This type of non toxic lubricant has been used for generations and it’s something most people will store in their kitchen or garage as a natural lubricant that’s free from that harsh chemical smell.

Non toxic, many people swear by using mineral oil to keep their gun lubricated. Unfortunately, if you use mineral oil for your firearm, you’ll find that you have to reapply it more often, compared to gun oil.

The Great WD40 Debate

WD40 has been the go-to lubricant for many gun enthusiasts over the years. However, as a lube this product is not the right alternative to a dedicated oil, which is petroleum-based. It’s also not a good substitute if the manufacturer recommends using a grease. In terms of protection, WD40 contains a large variety of chemicals that may potentially cause damage to wood and metal finishes, so you should avoid using it for firearm protection.

WD40 does a great job of lifting moisture from certain metals and between tight metal components. If you’ve accidentally dropped your firearm in water or it’s been exposed to rain, then using WD40 is a great way to get all of the moisture out before rust has a chance to take over. However, once this step is done, you’ll need to clean your gun as usual, after which you should apply a coat of oil.

Don’t Buy into the Hype

When you’re shopping for the best gun oil, you’ll come across plenty of products that claim to be this year’s miracle product. Unfortunately, there’s really no miracle gun lubes out there. While today’s oil technology is more advanced than what it was years ago, thanks to new additives, most of these new miracle products are nothing more than a different combination of additives that are only slightly different from what you’ve probably already used. You’ll also find that some are overpriced and total garbage. So, if you happen to stumble across the next big thing in gun oil, if  it’s overpriced, keep on looking. You’re sure to find a similar product that works just as well or better, for a price that won’t hit your wallet too hard.
