A little known product is HilCo Lube in aerosol and wipes.
When I was working on the 16th Cavalry officer side of the Armor School, the Marines brought up a tub of them that they had used during OCS at Quantico. Hill Company actually specializes in commercial and industrial cleaning gear, but this product impressed all of us and I have used it ever since.

My Unit Armorer instructor at Fort Lewis – a retired Master Sergeant by the name of  Butterfly – apparently had a standard joke he would roll out for each class when asked if there was something better than CLP.
His answer was;
“Yes, there are better products than CLP, but it has one overriding quality that really can’t be beat….(long pause)…..it’s free.”

Best Gun Oils for All Guns

Shooting is a ton of fun, but it’s also inherently dirty. There’s powder residue, carbon fouling, copper and lead buildup, and more.

Whether it’s your granddad’s single-shot shotgun that you’re going to pass down to your own kids or a brand new long-range shooting rifle that you spent far more on than you care to admit, the goal is to keep them both running smoothly for decades to come. In order to do this, you’ve got to keep your guns clean. Regardless of what it cost or how old it is, the best way to do this is to use the best gun oil.

Things to Consider Before Buying Gun Oil

Just as there are a wide variety of guns on the market to choose from, so, too, are there a bunch of gun oils to decide amongst. Here are a few things to consider when choosing gun oil:

Intended Purpose

Most gun owners own more than one gun. The reason for this is because different guns serve different purposes. As such, you’ll want to use different oils for guns with different purposes. Here are some things to consider:

• Self-Defense: If you’re going to be using the gun for self-defense, you’ll want to make sure that the oil you use won’t have an adverse impact on your gun’s reliability. Make sure it doesn’t attract dust or lint particles, doesn’t get gummy over time, etc.
• Competition: Guns used in competition need to be smooth shooters. Pick an oil that offers top-notch lubrication in this case.
• Collectibles: Preservation is the name of the game here. A gun oil that doesn’t break down over time is a good option here.

Frequency of Use

You might have a couple of guns that get used regularly. Others may only come out of the safe during certain hunting seasons. If this is the case, then you’ll want to choose different gun oils for guns that see lots of use and guns that see only occasional use. Here are some things to consider when choosing a gun oil based on the frequency of use:

• Thickness: Some gun oils run like water while others plod along like syrup. Thinner oils are good for overall lubrication on guns that see frequent use, but a thicker oil will last longer on guns that aren’t shot as often.
• Scent: This might seem like an odd one to put under the frequency of use, but I promise it makes sense. If you only use a certain gun during a specific hunting season, then the scent is actually a big deal. A lot of hunters put in a good deal of effort to keep their scent signature down when in the field, and an aromatic gun oil will kill all that effort in an instance.

Climate

• Thickness: Thin gun oils spread more easily than their thicker counterparts, but they also evaporate more quickly. Choosing a thicker gun oil is better in a more humid climate because it will stick around longer – literally.
• Prevention: If you live in a coastal location or a place with high humidity, rust is going to be a bigger concern for you than for someone in a more temperate climate. Thankfully, there are plenty of gun oils that offer great rust prevention.

Anyone who has been around guns for five minutes has heard of Ballistol, CLP, and Hoppe’s. They’ve all got loyal followers who have been using their products for decades and for generations. However, if you want to go with the best old school gun oil, the choice is clear: go with Hoppe’s No. 9 Lubricating Gun Oil.

The Hoppe’s No. 9 line of gun care products is legendary. The company’s lubricating oil has a high viscosity to prevent gumming or hardening for an extended period of time. You can buy it in bottles, pumps, aerosol cans, and jugs to best fit your needs. Because it is part of the larger No. 9 product family, it works incredibly well with the gun solvent and grease.

Best Gun Oil Wipes: Clenzoil Field & Range Saturated Wipes

Key Features 

• Perfect for quick use
• Can also be cut and used as bore patches
• Cleaner, lubricant, and rust preventative

You won’t always be in a situation where you want or need to do a complete teardown, cleaning, and oiling of your gun. Sometimes, you just need a way to quickly oil down your gun and move on. One of the best ways to do that is with the best gun oil wipes, Clenzoil Field & Range Saturated Wipes.

Pros

• Formula is time-tested
• Convenient application method

• Wipes only come in one size

The green oil offered by Clenzoil has become iconic, but a liquid gun oil isn’t always ideal. To remedy this, Clenzoil created these wipes that are ideal for a quick and easy wipe down after a day in the field or on the range. Each container comes packed with approximately 50, 5 x 7-inch cotton fiber pre-saturated wipes, which ought to keep you good to go for quite a while. The only downside is that you might not need a full-size wipe every time, and so then you’ll be slowed down by having to cut pieces off or sacrifice a full-size wipe.

Clenzoil is another company that has been around for a long time. It was founded in 1948 by a World War II vet and thousands of gun owners swear by their products. Being able to have their oil in a pre-saturated wipe just makes things all the more streamlined for quick care wipe downs on the go.

For this, we’d recommend using Break Free Collector Long-Term Protectant, the best gun oil for long term protection.

Methodology

In my years as a firearm historian, I have used a variety of oils to ensure the arms in a collection stay protected. The number one concern of someone charged with the preservation of museum objects is to ensure their proper working order and their longevity. As such, I’ve also had plenty of conversations with colleagues at similar institutions not only in the US but around the world regarding what we think works best.

I chose the oils on this list with a variety of criteria in mind, including:

• Cost: In general, gun oils aren’t expensive. Still, money doesn’t grow on trees. You don’t want to waste your money on products that over-promise and under-deliver. You won’t find those here.
• Prevalence: If you see a certain product on every gun bench, chances are high that it isn’t a coincidence. There are some gun oils that are found everywhere and have been for decades, and that’s with good reason.
• Application: The gun oils on this list are available in a variety of application methods. This is important because not everyone wants or needs a giant bottle of oil when a precision applicator or wipe is really needed.
• Performance: If a gun oil doesn’t work well, then it isn’t worth using. That’s pretty simple, right? It’s got to be trusted to clean, lubricate, and protect your guns.

FAQs

Final Thoughts on the Best Gun Oil

Choosing a good gun oil is very important. But thankfully, it isn’t expensive or difficult to do. There are so many options on the market that it’s really hard to pick a bad gun oil. However, that doesn’t mean that every gun oil is right for every situation every time. They’ve all got their pros and cons, so just be aware of what they are before you buy some. Really and truly, though, gun oil is just like everything else in the gun world: you’re going to buy more than one kind over the years before you truly find the right one for you. It’s just like choosing ammo, holsters, etc. You can never have too many options.
