Well...I would say, that Lube, is short for lubricate, which is oil.
Grease, means grease, not oil. Ergo, Vaseline.
So yeah, Vaseline on the regs and "light gun oil" anywhere else.
And it would not make sense for Eclipse saying "Vaseline" to be marketing BS, because as stated, it's cheaper than anything else.
If they said ONLY use Eclipse Gun Oil, then that would be marketing BS.
Eclipse don't BS, they don't need to and they know, that we would know they are talking crap...they don't insult your intelligence in that way.
