Lucas Gun Oil > MPro7...I think

[WDR]

FireClean FTW!... Also works for seasoning cast iron, in a pinch.

Kidding.

As of late I've been using EWL30... but I also have half a gallon of CLP that I still need to use up. I've tired various lubes over the years, and nothing really stands out, other than dry guns don't like to run, and really cold temps (below say 15 degrees)can do weird things with lube.

Grease has a place, but most of the time oil is going to be sufficient for firearms use.

I have accumulated a number of lubricants, some even GUN Oil, and have found that the best lube is some.

I do think Lucas is good stuff, but I have too much other stuff on hand and won't likely buy more when my free sample runs out.

I have most of a case of Mobil 1 in the garage left from when we had a functioning minivan. Probably a couple lifetimes supply for me now

While they did not test all brands, and specifically Lucas Extreme Duty. I thought this video, which is somewhat scientific was interesting:

I recently used a sample pack of Lucas Extreme that came with a Sig I was given. I really like how it went on compared to what I was used to (Hoppes). It seems to sit and stay where you put it rather than just getting everywhere and having wet hands by the end of re-assembly. I haven't shot it yet on my guns, but they feel a lot smoother and I don't feel as much friction on the slide.
