I did. Let's assume for the sake of argument that he knows what he's talking about. Here are his key points:
BAD:
Motor oils: Generally good boundary lubrication (particularly the Havoline formulations), but very poor corrosion resistance and poor resistance to open-air oxidation. In addition, their pour-point additives often contain benzene compounds, which aren't a good thing to have next to your skin on a regular basis! ATF performs better for firearms use on every count, even if it is a tad more expensive. (ATF is still 1/10 to 1/100th the cost of a specialty "gun oil"!)
Automotive motor oil additives: Usually a boundary additive in some sort of light mineral oil carrier, they usually lack corrosion protection and often oxidize rapidly; some have poor migration characteristics and rely on the oil to which they'll be added to provide those things. There are better and cheaper alternatives, though when mixed with an appropriate oil additives do have some merit (see above.) By themselves? No.
GOOD:
Dexron-type Automatic Transmission Fluid (ATF): Scores pretty well in corrosion testing is also the readily available and dirt cheap. It also has good migration, a good boundary lubrication package, is the right weight (thickness) for general firearms use, doesn't oxidize over long periods of storage, and is compatible with a wide range of metals and plastics. In addition, it is recommended by at least one real degreed firearms engineer!
"Best in Class" (his words):
Lubriplate's FMO-AW oil (350-AW weight): This is an oil designed with very high boundary protection and very high corrosion resistance - especially in the presence of acids, alkalis, and moisture. It is darned near tailor-made for our use! (Note that it's also non-toxic and certified by the NSF as safe for "incidental contact with food.")
So this guy didn't actually compare any "gun" lubes (he mentioned Rem Oil in passing but that was it.) He completely skipped over a number of gun lubes that would seem to meet his criteria, many of which share more common ground with Lubriplate than ATF. I'll concede that ATF is cheaper, but based on his own analysis it's not "best."
Let's assume that firearms manufacturers know whats "best" for their products. Do any of them recommend using ATF? If it was indeed "best" why wouldn't they recommend it? A vast conspiracy of firearms manufacturers colluding with lube peddlers to squeeze us for a $10 bottle of purpose-designed gun lube that will last the average shooter a lifetime? Seems doubtful to me, but I've never been big on conspiracy theories.
