I know people say the best lube is high weight Mobil 1, but what about this Harbor Freight Tools 3-in-1 bottle? Does anyone use this on their AR-15?

Nah you gotta use something marketed for firearms use that costs at least $10 an ounce

It says Marksman Twist on the bottle, sounds like a gun thing. (seriously tho, i just happen to have this in the house and dont feel like getting a separate bottle of mobil 1 like some internet troll)
 
It doesn't matter.

Guns are not a challenging environment for oils. It's not like an engine reving at 7,000 RPM. Yes, any 3-in-1 oil will be fine. The reason many of us recommend engine oil is that it comes in large volume bottles and so it is cheap. Buying gun oil in 1 oz bottles is stupidly expensive in comparison.
 
Basically all my guns run fine on any oil, CLP etc.. but I do have one AR PCC that is a dirty girl and will start jamming after only about 40 rounds. Just gunks right up. I tried a bunch of greases and landed on: Lucas Oil Extreme Duty Gun Grease. And now I just put that on everything and a little bit of oil. I use the Lucas oil as well, but if it's not nearby then just toss CLP in. Specifically on that AR I was having the issue with. Using the grease and lucas oil I went from jamming consistently after 40 rounds, to going over 500 rounds and even using low power ammo and changing out buffers just trying to make it jam.. wouldn't jam. Lucas grease and gun oil is in my range bag now.
 
I have talked on the subject with various (high end) gunsmiths and the common thinking is that frequency of cleaning and lubing beats quality of lube as long as you don’t cheap out badly. I use Mobil 1 0-40 around the year. Clean and lube after each shooting session.

I can't believe WD-40 went the longest without rust in the rain. Although it was some "Specialist" variant. I was always told that WD-40 is not a replacement for grease when you need it to last, as WD-40 evaporates over time. I guess that's regular Wd-40... I just realized I have a bicycle sitting outside and I should probably go spray the gears with WD-40 for the winter.
