These two agreed to disagree. One said it was fine and the other didn’t recommend it. I can tell you first hand, it’s fine. Never had any problems with rust on any of my guns. If it’ll work in a car engine, better believe it’ll work the gun. Both agreed it’s a good lubricant. Love the smell of it and it really helps any wood your gun has. Makes it shine.

I try to use the best tool/equipment/product for the job. I side with the guys, including some engineers I know, that talk about differences with car engines because that oil is continuously run through a filter and is designed to be separated from the environment, vs the wide open to everything that’s out there firearm application.
It’s not like dedicated/marketed firearms products are expensive, really.
That said I know guys that use automotive engine oil to lube their firearms and none have any complaints yet.

I’ve been using Mobile 0W30 for my striker fired pistols and never ever got single problem with lubrication and rust.
You must only remember - motor oil is thick and do work ok with mass production firearms. I’d not recommend it for high quality pistols with tight fit, where there is no a lot of space for lube. These need thin oil, like Wilson Combat or Hoppe’s Black.

Great info - even for today, June 2025! It gets so confusing out there with products able to print any claim they wish without verifying if it works or not. I’ve taken his lead before on Milwaukee products, in HVAC he was spot on. We have too many firearms at home, and I needed a faster and better way to clean them. It’s Cleanzoil or Break Free for me. Thank you for the video - it helps!
