Gun Oil Friction Test – Otis Bio CLP

Otis Bio CLP is a fairly new product and I have used it on some of my guns. It seems to work well and is non-toxic. It’s really hard to determine how well a lubricant works by testing it on a firearm. You have no way of measuring its effectiveness. That’s why I’m using a scientific friction test. It provides comparable data.

I’m using a simple inclined plane/sled setup to measure friction reduction. Here is the setup…

Gun Oil Friction Tests

This is the 1/2″ x 4″ x 24″ 6061-T6 inclined plane that has been filed true and polished to 400 grit.

Inclined Plane Friction Test

Here is the 1″ x 2″ x 4″ 6061-T6 sled or block.

The Test: One end of the inclined plane is raised until the sled or block slides downward then the incline or slope is measured with a Wixey digital angle gauge. Oil should reduce the friction and cause the sled to slide at a lower angle than bare metal. Bare metal slides at an average of 15 degrees of incline.

I always clean the metal surfaces before each test using M-Pro7 Gun Cleaner. It’s a great cleaner and leaves zero residue plus it’s totally non-toxic and doesn’t smell.

I apply Otis Bio CLP directly onto the inclined plane and the sled in the form of several drops. I then took a few clean patches and spread the Bio CLP evenly. I then take several more patches and wipe off all of the excess. This leaves a very thin film of Bio CLP.

I place the sled on one end of the inclined plane and raise it until the sled moves. I then record the angle from the Wixey digital angle gauge. I repeated this procedure 10 times and then averaged the data. The average angle was 13.77 degrees. Remember that bare metal was 15 degrees. So Otis Bio CLP reduced friction by almost 10%.
