I’ve used a lot of TW-25B and the oil. I started using it with Para Ordinances around the turn of the century. It’s worked fine for me, as have many other oils.

I still use it on my pistols for one main reason. I love the smell.

 

Guys, ALL grease is formulated as an oil plus a thickener (aka ”soap”). Most of you would be surprised how ”thin” the oil component is in most greases.

Typical soaps are lithium, sodium, calcium, and a half dozen other chemistries. (OK some are technically not soaps but are still thickeners like polyurea and various clay formulations. Bottom line the soap thickens the otherwise runny oil).

With that said, the only reason to use a grease on a gun is because you need it to stay where you apply it. On guns that means a “grease” with enough thickening agent to not flow and no more.

I’ve had good luck with Tetra and ALG (Geissele), and gun butter. There are others and they probably work fine assuming they don’t have a stupid fomulation that hardens with time\O2 exposure (Frog Lube anyone?)

And as far as I’m concerned, TW25b was never the “gold standard”

 

I use TW25B on all my guns. I much prefer it to the oils.
