Things You'll Need

  • 2 cups automatic transmission fluid

  • 1 cup 10W-30 synthetic motor oil

  • 1 cup oil treatment, such as STP

  • 32 ounce bottle with sealing lid

  • Permanent marker

Several kinds of guns need to be well oiled.

Guns are used mainly for protection, hunting or serving the public in a professional capacity like law enforcement. No matter how you use your gun, or the type of gun you use--rifle, shotgun or pistol--each time you fire one, it needs to be thoroughly cleaned to prevent rust and backfiring. Cleaning includes oiling all components and is a part of gun safety. If you purchase a bottle of gun oil, it can cost around 10 dollars for a few ounces, as of 2010 prices. You can make your own oil for considerably less than that and have more than a few ounces to show for it. The best part is that you probably have the ingredients sitting at home in your garage.


Step 1

Use the permanent marker to label the empty bottle "Gun Oil".

Step 2

Pour the automatic transmission fluid, synthetic motor oil and oil treatment in the bottle.

Step 3

Screw the lid on the bottle and shake vigorously for two minutes to thoroughly mix the oils. Each time you use this oil, you must shake it vigorously to mix the ingredients.

Step 4

Apply the mixture to your guns during the cleaning process.


In order to mix the solution more quickly before each use, fill up a bowl with hot water and place the bottle into the water. Let it sit for 5 minutes and shake around. The heating up of fluids will also give you more usage out of the oil because it thins it out without taking any of the properties away from it.


Guns can be dangerous. Exercise extreme caution when handling guns to avoid injury to yourself and others. Store well out of reach of children and household animals.

This solution is highly combustible. Do not use flame or fire around this product to avoid combustion and injury to you and others around you.
