Lube

[Phil-Himself]

what kind of oil is good for Classic Valves, other than the AGD lube. I know pertrolium distilates eat away at orings. also, does the xvalve need to be lubed, and does it use the same stuff?

Use KC.
There are a few people here selling it for $5 a bottle.
Can't be beat.

KC, the blue stuff. Use it in my XValve.

The X-Valve most definitely needs to be lubed. In fact all guns with o-rings (all of them) need to be lubed. Dry o-rings create an incredible amount of friction.

KC is the best oil out there for paintball guns. For a more economical approach, it's okay to use the silicone oil used for RC car shocks. You can get it in different weights and 20wt is ideal for paintball gun valves.
