Gun Oil Buying Guide:

What You Need to Know to Make the Best Selection

gun oil reviews

First and foremost, you might be wondering why lubrication is such an important part of routine firearm maintenance. This, like most aspects of firearm maintenance, is not that difficult. It just takes a little experience and choosing the right oil for the job. Lubrication is important as it helps to prevent wear and tear on the firearm and to allow it to perform at its highest level. In order to achieve both of these aims, you need to keep the moving parts from directly rubbing against one another as much as possible.

A nice layer of oil literally helps to grease the inner workings and allow them to function with minimal friction, thus reducing wear and tear. Not only will keeping your firearm appropriately lubricated ensure that it works at its optimal level of performance, it will also extend the life of the gun. In short, lubrication is part and parcel of responsible gun ownership. It keeps the firearm functioning properly and without undue friction.



It is probably most accurate to say that what you want for your gun is more akin to grease, which is simply a thickened oil. With grease, oil is mixed with one of a variety of bases to achieve certain characteristics depending on needs. The base is most commonly a metallic soap-like substance. Some of the bases will help reduce oxidation. Other bases are meant to help improve the firearm’s resistance to water or extremely cold weather. Depending on the environment you will be using the firearm, the type of base that will work best will vary. There are different grades of grease too. They are denoted with what is referred to as an NLGI number. The smaller the number, the thinner the oil/grease is. The higher the number, the thicker the finished product. This can be very helpful when determining which is the best type for your needs.


AW/EP (anti-wear/extreme pressure)

When you begin to look at different gun oils, one of the first things you will notice is that there are a lot of specified additives that are utilized to provide different functionality when added to the oil. You will see AW/EP quite frequently when looking at gun oils. This means anti-wear and extreme pressure. A good quality gun oil is going to have a lot of these additives to help keep the gun in the best working order possible. These additives are tiny solids that are mixed with a straight oil to thicken it and add additional properties to the mixture. There are a huge number of different mixtures that are tailored to particular needs, concerns, or environmental protections.

Commonly added compounds include:

  • antimony dialkyl dithiocarbamate
  • sulphur compounds
  • boron
  • zinc
  • phosphors
  • polytetrafluoroethylene
  • zinc dialkyl dithiophosphate
  • tackifiers
  • detergents
  • pour point depressant

There are literally hundreds of different additives that are utilized to give the final product the desired thickness and other properties.



Depending on whether or not you plan on using your firearm often, or storing the gun for later use, the type of oil that will work best for you will vary. Guns that are well maintained and cleaned will fire properly every time, even when coming out of long-term storage. If you live in humid southern regions or salty coastal areas, rust will be a bigger concern than for those who live in more temperate areas. Gun owners who live in these regions are encouraged to use a gun oil that has a lot of rust prevention additives.

If you are planning on using the gun in extreme cold, you will want to look for an oil that is specifically designed for these conditions. There are a huge wealth of different products to choose from. The brands reviewed here are, by no means, the only good gun oils available on the market. However, they are some of the most popular and dependable brands that are the best value for the money. It helps to know what type of protection and use your firearm will need and experience. This will help determine what formula of oil will work best.

It is important to understand the basic components of gun oil and what you need for your firearm. There are plenty of new products that are added to the market each year that tout themselves as the best, but too often we just end up with a few bucks less and a useless product. These oils come in a wide range of formulas and come with a wide range of price tags. There are a lot of gimmicks in the firearms market, but oil is not one of them. This is one of the most important aspects of routine gun maintenance and a high-quality oil is worth the money and will prove itself by providing continued optimal performance every time. Guns need to be cleaned and oil well and often to help ensure they work their best.


What Does Gun Oil Actually Do When You Apply It to Your Firearm?

best gun oil

As noted earlier, gun oil is intended to act as a barrier between moving parts. This is used to help the parts slide across one another easier and with as little friction as possible. You may look at your firearm and see a perfectly smooth metal surface, but, in fact, this is not the case. If you look at your firearm under a microscope, you would see that the surface of your gun is, in fact, pitted with tons of tiny little craters that, if left unoiled, will grind against one another and cause wear and tear to your weapon.


When you apply gun oil to your firearm, you fill all of these depressions with a slick substance that aids in reducing friction and allowing the different mechanisms to function without contact. This allows the firearm to function at its optimal level of performance and also reduces undue wear on the weapon as well. In technical terms, this is what is referred to as “hydrodynamic lubrication.” The gun oil allows the moving parts of the gun to “ride” along the oil to aid in friction-free movement. The only problem is that without what is called a “boundary,” which is an additive that thickens the oil, the oil will simply squeeze out of the nooks and crannies when the firearm is engaged.


A gun oil with an added boundary substance will have more solidity that will allow it to coat the inner parts of the gun in a way that won’t just be pushed out when the gun is engaged. The boundary substance helps give the gun oil its protective qualities that keep the pieces from wearing each other to nothing and ruining the weapon. Gun oils are also designed to provide an array of protections for your firearm as well. Many of them include different anti-rust agents, anti-wear agents, and compounds that are designed to handle extreme pressure.


Depending on where you live and what kind of use your weapon will see will determine which formula will work best for you. Oftentimes, there are detergents that are added to gun oils. This means that when the oil is applied, it is also working to break down dirt and other grime that might gunk up the gun. In short, gun oils also work to clean guns as well as keep them lubricated. This is important as grime and dust can get inside a gun and cause it to malfunction. Guns need to be cleaned as a part of routine care.


If you have chosen a 3-in-1 gun oil, you have a product that is intended to clean the gun, lubricate the gun, and to provide protection against things like water and oxidation. These products provide a great all purpose solution for routine firearm maintenance. They might not be suitable for all needs, but for general purpose maintenance, they do work pretty well. A lot of people like this option due to the simplicity of having just a single product to apply, as opposed to a number of different products for different purposes.


8 Important Facts That One Must Know About Gun Oil


  • 1) Gun oil cannot solve all problems. If there is too much wear and tear or there are broken or aging parts, no amount of oil, no matter how high quality, will fix the problem. Guns still need to be taken apart and cleaned. You cannot rely on gun oil to clear all grime and debris, though it does work well for regular maintenance.
  • 2) Most of the “failures” of gun oil have to do with user error, not any problem with the oil itself. You need to learn how to properly oil the gun. There is such thing as too much or too little oil and using too much or too little can cause problems with the firearm. It is important to be sparing in your use of gun oil. A little goes a long way, but at the same time, you need to make sure that everything is adequately lubed. Finding that sweet spot takes practice and experience, but once you find it, oiling your gun will be a snap.
  • 3) There’s no such thing as a miracle gun oil. Companies that make gun-related products are no different than any other company. They are out to make money. To do this, they need to regularly introduce new products and then create hype so that people go out and buy them. Oftentimes, these products claim to be “miracle products” and come with a hefty price tag. Don’t be swayed by gimmicks. Do your research and find a good value that does what you need it to do. If it comes with a lot of bells and whistles, chances are it is just a money sink and an old standard works better at half the cost.
  • 4) Gun oil is often formulated for specific environmental conditions. All-weather formulas exist that will do the trick in any condition, but there are specially formulated blends that are designed for specific environmental factors.
  • 5) Regular use of a high-quality gun lube is a great way to improve performance and extend the life of your firearm.
  • 6) Gun oil is actually a formulated blend of oil and a variety of different additives. Some of these additives are to make the oil thicker. Detergents and other compounds are added to many oils to give them cleaning properties. Anti-corrosive agents and those that help improve water and weather resistance are also added.
  • 7) Boundary agents are added to pure gun oil to give it enhanced properties and to make it thicker. These agents are what keep the oil from simply squirting out of the places it is needed when engaged. Boundary agents make the compound just thick enough to stay adhered to the surfaces where it is needed, but not so thick that it causes the mechanisms to get stuck or be prone to build up.
  • 8) The most expensive kind is not necessarily the best kind. A high-quality gun oil is not going to be the cheapest brand on the market, but it is not the most expensive one either. Look for a trusted brand with a reputation for quality. Any of the brands reviewed above are great values for the money and work for a variety of different needs.
