This conversation was starting in another thread. I thought it deserved a thread of its own.
EDIT: I just checked the Material Data Safety Sheet of the Hoppe’s Synthetic Blend Oil and found it to contain 97% mineral oil, i.e. petroleum distillate. So it doesn’t appear it would be any more or less damaging to plastic gun components than old fashioned gun oils. The term synthetic must simply refer to the special lubricants included in minor amounts in the formulation like molybdenum sulfide and Teflon.
Shall we discuss?
You raise a good point that I had never considered before. As a plastics material scientist, I should have thought of this before. I have had two cans of standard gun oil (Hoppe’s and Sears) for 40 years since my only gun was a Security Six stainless .357. When a I started really shooting 5 years ago, I just started using up those petroleum oils even though now a couple of my guns have polymer frames. I don’t think there is a problem with glass-filled nylon, but why take a chance. I will order some of the synthetic. Thanks.As far as using engine oil for lubrication- even "synthetic" engine oils use petroleum base stocks and I would be hesitant about exposing a poly-framed pistol to them for any length of time, just because petroleum oils, plastics, and rubber don't play nice together. Hoppes Synthetic gun lube is petroleum free and would be my first choice. Just my 2c....
