A couple told me that someone online(ie PBnats) told them not to ever oil there guns!
Wow. That's bizarre.
I think the problem is that kids assume that what's "good" for electropneumatic spool valve platforms is good for everything else. I can't even begin to list the problems I've seen because someone decided to lube their Spyder or Cocker's lower and upper tubes with copious amounts of Lithium Grease. Hell, Lithium Grease isn't even good on Spools. That stuff turns to sludge as soon as it hits the windchill from a butterfly's fart.
