These have been my cleaning mainstays for years but I think I'm ready to bail on Rem Oil. I swear their new formula is different, I had the same handful of old ass bottles forever and finally had to try a new one and the stuff mostly dries out overnight! Yes things will be clean and it's better than nothing but I feel like it's just WD-40 now, you can feel the "water displacement" but it's not an active oil type of lubrication. I know this industry is as close to "snake oil" as you can get with the hype around different lubricants. Every time the autists get involve and do testing, most of these products are just regular motor or vegetables oils diluted down some. My car uses 0W-20 synthetic and I love the stuff on tools, I think I'm going to transition over to it on my guns for a while and see how it goes. THR has a 10 year old topic about it which I just found while making this thread, classic stuff! https://www.thehighroad.org/index.php?threads/mobil-1-synthetic.291494/ My main issue is avoiding greasy stuff that leaves residue, hate that especially on carry guns. Rem Oil used to be the answer because it semi-dries but the new formula is just too dry in general ... I'll probably continue to use it for blasting nooks and crannies since I have a big can of it but for basic oil-on-patch duties, I'm jumping over!
