Honestly, I can't answer, but I can say and there will be some that will venimently call me names for this or being a liar, but they can go ..... themselves. That said, put some silicon on my threads, a day or so later I read, ON THIS FORUM, that silicon oil is not for metal to metal anodized contact. My threads had been fine when I did it, afterwards the anodizing was GONE. Personally, I'd prefer to err on the side of caution. I also believe that there is close to zero need for silicon oil in an airgun. Everyone is worried about Dieseling, IMHO you aren't going to have that simply coating threads or an o-ring with a light coat of oil. My personal favorite is Mobile 1, the lightest you can get. Mobil 1 is an excellent lubricant and very very very long lasting. It doesn't attack anodizing or Nitrile 0-rings. I use it on my AMP regulators on my Mavericks and have had ZERO issues. Can I say the o-rings last longer, no I can't but I haven't had to mess with them in over a year. I've used the stuff on my Pew-pews for over a decade they just go pew and my air guns still work. My opinion is, if it slides lube it with something slippery. I use the stuff on my $20,000 embroidery machines, some are over 20 years old and are still running perfectly and quiety. I use to have to lube daily now...once a month and it's been a LOT of years. The ONLY reason not to use oil on moving parts is if you're crawling in the dirt or sand, from what I've seen, our guns are as far removed from that as humanly possible.
