Okay, this arrived today:
Smells like Methylsalicylate/Menthol (BenGay). Haven't "tasted" it yet.Anyways, here's an excerpt:
"It. . .will clean & moisturize skin." Hmmm. . .
Will see how it "performs" as it's intended.
Mostly I use Mobil 1 with a hint of Slick 50 in it.
I do like Otis Tech Dry Lube too.
I've used Hoppes 9, WD40, SW014, One Shot, Remmy DriLube, Otis Tech and all kinds of Motor oils.
I do keep some WD40 in my range bag just in case. In case of what? No idea.
The difference between a revolutionary and a dictator, is a matter of timing.

Ok, I have been holding back on this topic for a while but I will say what I have to say. I wouldn't go near any of my rifles or guns with motor oil, forget WD40! motor oil is just that, MOTOR OIL (engine oil),which contains additives and detergents for CAR ENGINES. I am in no way an expert on this topic but the only way I would use a lube like motor oil is if I was in a situation where I had no other choice to keep it lubed. Just my honest opinion. Any chemists want to chime in and possibly convince me otherwise?
Break free CLP and Slip 2000 EWL for the most part. Grease on specific applications.
Reciprocation metal parts is reciprocation metal parts. The motor oils out there are designed to work in much tougher conditions than a gun.
Not wanting to rewrite any of this myself, you must look at what the oils are designed to protect against, not where the bottle says it goes. Here is a good summary:
Since Mobil 1 is subjected to such extreme conditions (in terms of thermal stress, oxidation and pressure) inside of an internal combustion engine, it appears that it should possess both adequate film and barrier strength to serve as a small arms lubricant.
The criteria that these lubricants were evaluated by are:
1. Pour Point (P/P): The lowest temperature (in degrees F) at which the lubricant will flow within a specified timeframe.
Minimum requirement: -50 F
2. Flash Point (F/P): The lowest temperature (in degrees F) at which the lubricant will produce vapors that, if subjected to an ignition source, will ignite and combust.
Minimum requirement: +450 F
3. Viscosity at 100 F (V/100): The viscosity (in centistokes) of the lubricant at 100 F.
Minimum requirement: 40.00 cSt
4. Viscosity at 212 F (V/212): The viscosity of the lubricant (in centistokes) at 212 F.
Minimum requirement: 8.00 cSt
As a point of reference, the kinematic viscosity of pure water at:
68 F (room temperature) is 1.004 cSt
100 F is 0.658 cSt
212 F is 0.294 cSt
5. Transient Operating Range (TOR): The sum of the absolute values of the Pour Point (P/P) and the Flash Point (F/P).
Minimum requirement: 500 F
6. Viscosity Index (VI): An arbitrary numerical value assigned to a lubricant indicating its ability to retain its viscosity across a specified temperature range.
Minimum requirement: 110 (Very High)
Low VI: 35 or lower
Medium VI: 35-80
High VI: 80-110
Very High VI: 110 or higher

WD40 is shit for guns, I'll give you that, it's not even a real lubricant.
A firearm isn't that much different than an engine; heat, pressure, and the presence of carbon are all common factors. IMO no gun lube will ever match the superior lubrication properties of a commercially developed synthetic motor oil. Motor oils are designed to withstand breakdown due to heat, actively clean and absorb carbon, and provide lubrication. I've used mobil 1 for the past several hundred rounds I've shot and there's no carbon stuck on the bcg, its all caught in the motor oil. The most extensive cleaning I ever do is a quick wipe down of the bcg. The one area I think lacking with motor oil is corrosion protection. An engine's crankcase is sealed off from the environment so I don't think corrosion protection was ever a major part of the design criteria.

I appreciate all the information and agree that as far as a lube, motor oil is superior in many ways. I'm weary of the additives and detergents, that are specific to engines and also the toxics/toxins involved that you are exposed to on different levels. If your ok running with these then I respect that, but I will stick to the ones mentioned: Break free CLP and Slip 2000 EWL for the most part. Grease on specific applications. Again I respect all of your information and impute and I am in no way trying to start a shit storm.

Sounds like Dri-Slide...

No, thats not the one I saw in the mag. It was a "new" product, in a new product section. But, that Dri-Slide does pique my interest. I wish some of these companies would send out samples for T&E. Wait, I think I still have some Militec samples that they sent me YEARS ago to try out.Maybe I will try that out, so I won't have EWL dripping out of my duty gun anymore.
Except Motor Oil is designed for a sealed system that is actively re-lubricated with an oil pump. It relies primarily on hydrodynamic lubrication.
A firearm is an open system with no active re-lubrication. It needs a lube that relies heavily on boundary film mechanisms to lubricate.
My brother saw Deliverance and bought a Bow. I saw Deliverance and bought an AR-15.
