Last few years, I've been using Aeroshell Fluid 18, marketed as suitable for use with "small arms and automatic weapons", but it's primarily a lubricant found in aerospace markets. I've never seen it anywhere else. It's mainly a refined, thin mineral oil with just a tad bit of anti-corrosion additives...nothing fancy but I bought a gallon to use with precision measurement tools because Starrett bends you over for a tiny bottle of their stuff. Its a similar oil to precision machine/tool/sewing machine oil.
To match it, I run Shell Aeroshell 33MS for anything needing grease. 5% molyndenum disulfide and lithium complex, slick as snot. No magic marketing or fancy additives. Just a strict grease used in the aerospace sector. The grease is $20 for a tube and $40 for a gallon of the oil. It's a lot up front but cheaper than paying $5-10 for tiny 1-4oz bottles.
I'd just as happily slather motor oil on the gun, or dig into my brother's big tub of minty froglube. I find the act of actually keeping a gun lubed is more important than the slight gains of one brand over another. Usually when you market an industrial or aerospace lubricant, there are 3rd party lab tests using standardized tests for wear, abrasion, etc. You rarely see that level of scrutiny or controlled tests with weapons lubes so it makes me wonder sometimes if the marketing borders on hype.
