We airgunners are a bit ocd, and with that in mind, I've tried to find a good grease for the GX compressors like the CS2's gearbox. The grease that comes with the unit is some kind of super tacky, thick grease, that does tend to last a while, but after some time it works it's way off the gears and it is never coming back, it is way too thick. Knowing that the lifeblood of one of these compressors is grease in the gears, I went on a search, and tried a bunch of different greases, and finally found a winner. Green Grease will work but it too migrates off the gears and soon goes the way of the do-do. Lucas Red N Tacky is very good and could conceivably last several months, but it also goes off the gears with time. This is my 2nd place winner. But for a grease that is so tacky it sticks and yet runs back after a lot of time, I will be using Chevron Open Gear Grease. This stuff is like molasses thick, and takes forever to run, but it DOES run down and can be picked up by the gears again. It is very tacky, like getting it on polished stainless utensils is hard to clean off. So it stays put a long time yet will eventually run down and back on the gears. I loaded up the driven gear and the pinion and then used just enough to create a puddle at the bottom of the gear case so when it does run down, the gear can pick it up again. So far, it is working fantastic. I think you could go a year of hard use with this in the gear case, in the proper amount, and it would be fine. I got a tube on ebay and it was $15 so it's not going to break the bank. Pictures to follow the next teardown, as it's hard with your hands covered in grease.
