I really do not feel the additives in motor oils and greases will hurt a firearm. But long term storage can cause issues as the lubricant evaporates over time.
One of the reasons I switched to using Mobil 1 oil and grease was my experience with other lubes snd greases that didn’t perform as well as I was led to believe they should. White Lithium became hard. Traditional mil-spec grease drying out over time. Synthetic gun oils with Teflon didn’t perform and I saw wear where I thought I shouldn’t. After trying Mobil 1 I stopped with all the others. Too bad there isn’t a market for partial bottles and tubes of gun oils and lubes. I have been using it for about 4 years now. I am happy with it...except for this last time I obviously got carried away with it. Even then it was no biggie. I just found it interesting how it migrated under recoil.
