That's an interesting test, but I suppose the results are open to a wide variety of interpretation. While the results suggest that a product like Frog Lube has outstanding performance, it comes at an exorbitant price. In one iteration of the lubrication test, regular WD-40 outperformed it. I suppose as a low-pressure friction reducer, WD-40 might be one of the better bargains out there, but I wonder how water would have performed in the author's test. In the corrosion protection tests, it looks like three products stood out: WD-40 Specialist, Frog Lube, and Hornady One-Shot. The products were tested under extreme exposure conditions but only for a short term measured in days. This doesn't necessarily extrapolate into long-term storage in conditions where chemicals other than salt water are working over a period measured in years. On the other hand, taking into consideration a reasonable amount of use, the protectant will wear off, be cleaned off, and need to be reapplied frequently. In those conditions, the less expensive products are more practical. One-Shot probably has the best results in this test for lubrication and corrosion protection for the money, but outside an environment with salt mist, it looks like regular WD-40 and Rem Oil are practically just as good or better.
FWIW, I'm not attached to any product. I'm currently using Ballistol, Break Free CLP, Hoppes #9 and Rem Oil. I use Renaissance wax for storage but I live in a very arid climate and it's not challenging. I like Ballistol for cleaning but I get impatient with it as a copper solvent and turn to #9. I have a small can of Break Free and the aerosol spray just sort of spits and dribbles. As a C, L, and P, it doesn't seem to do any of them remarkably, but it hasn't really failed either. I love the fine mist aerosol on my can of Rem Oil and the can seems to last forever. I lubricate my reloading press with it and occasionally wipe a gun with it and otherwise use it all around the house and garage like someone would use regular WD-40.
After reading those test results, I'll probably get some WD-40 Specialist for my rotary push mower. Sorry Frog Lube, I just don't love the mower that much.
I'm interested in a lubricant for revolvers. According to the test, regular WD-40 is one of the best. I can see how WD-40 might produce less friction in a fidget spinner bearing, but I'm going to keep the thick axle grease I have in my 4x4's wheel bearings. Revolver actions? Lithium gun grease has a higher film strength but tends to collect contamination. A light, dried coat of Rem Oil probably has less film strength but won't collect as much grit. Since I clean and lube them often, I probably can't make a difference either way.
