Can I Use 3-in-1 Oil on My Gun?

Most gun owners would not recommend using 3-in-1 mainly because it gums up pretty bad. It also does not have rust protection. It was pretty popular back then. However, there are oils that are specifically catered to for maintaining guns.

What Is 3-in-1 Oil?

The 3-in-1 oil is a multipurpose oil used in most households since 1894. It is a flexible formula that you can use to clean grime, lubricate components, and provide some protection from rust. That’s why it’s called 3 in 1 oil.

You can use 3-in-1 oil in almost every tool and equipment that requires oil for maintenance. That’s why it was popular before CLP came up. Be careful, as 3-in-1 oil can cause gumming, especially in dusty areas.

3-in-1 oil is now owned by WD40, so they made clear differences with it compared with other lubricants. 3-in-1 oil is meant to be for general use, so you shouldn’t expect it to work effectively with guns.

Pros of 3-in-1 Oil

If you’re considering using 3 in 1 oil, here are some advantages of using 3-in-1 oil:

  • A pure oil-based product
  • Lighter for flexible use
  • It can be used with other items outside of guns
  • It saves you money  since it’s multipurpose

Cons of 3-in-1 Oil

If you weigh in between other options, you should also know the bad things to know if it’s a dealbreaker:

  • Can easily gum and attract dust
  • It can clog up when you apply too much
  • It is not as effective as WD40 when it comes to protection
  • Outdated and outclassed by modern oil products
