Post Gearbox Greases

I'm sure this has probably been posted in the past, but I figured I'd shed new light onto this since we're bringing life back into the forum. Admins delete if not allowed, pls no banhammer.

I'm not responsible for what you do to your guns, nor am I telling you to try this. This is my own test and my own research.

For a long time, white lithium has been the only gearbox grease that I've heard of people using due to it's lack of any sort of petroleum, which is used in the mixing of rubber and therefore also breaks down rubber, thus destroying your o-ring and your bucking.

As the years have progressed, guns are getting faster and just generally getting more advanced. Electronic triggers and such really increase trigger response and allow for a much faster cycle. I've been hunting for a thicker grease to better withstand the higher amount of stress. This involved delving into ingredients into different types of greases and there uses. One that I found in one of my other hobbies, is wheel bearing grease. Now obviously there are different blends of this stuff, but I would imagine that there would have to be little to no rubber dissolving ingredients as wheel bearings are sealed units. However, I did not test wheel bearing grease nor did I investigate its ingredients.

One night after getting off work, I checked the local Walmart to see if they had anything I could use. I came across a multi-duty, hi-temp grease in a small can. The can says that it is a "lithium based complex". It contains: paraffinic oil (Essentially kerosene), mineral oil (heavy), and lithium soap.

Now, a lot of you may recognize these and think: "Hey, some of those eat rubber!". Well I thought that too actually. I decided to do some research on what these ingredients actually do to rubber. Now, granted, a lot of what I read is coming from the automotive world, but I would think some things would carry over. My job is also manufacturing rubber. I currently make window seals for Honda, so I've been looking into what our R&D team uses.

Kerosene is actually a common cleaning agent on engines that have a lot of exposed plastic or rubber seals because it's not as corrosive as brake cleaner or similar cleaners. Kerosene also leaves a thin film on metal, as I discovered today while using GUNK automotive degreaser, which definitely contains kerosene - you can smell it.

Mineral oil is a big one I read into because it DOES contain petroleum, but it has been used in the creation of submerged gaming computers and there are plenty of rubber components that are definitely not automotive grade inside of our PCs.

Lithium soap is essentially a form of white lithium, which we all know what that is.

I am currently testing this in two of my guns. One of the guns I packed the gearbox full of grease, and immediately noticed that it did not stick as well as I had hoped as I was getting literal globs out of coming out of the air nozzle. Had that gearbox actually been mated with a barrel, it would have completely permeated the bucking and barrel. The other gun I am currently testing it on, I only applied a very small amount to a few teeth and on the gear axles to help alleviate friction between the axles and the bushings. If I remember to post updates on this, I will.

What does everyone else use, or is everyone still using the tried-and-true white lithium?
