That's interesting. Never really thought much about it but I can see where the higher viscosity might help with any throttle stall in the higher vacuum ranges.
I've always tried to stay in the 15-20 wt range on my skinners. ATF falls into that range nicely where as MMO runs abit lower than that on the scale.

Worked at a store with a guy for 13+ years ,he bought a brand new for pick up in the mid 90's added m m oil at every change....3years later ....new motor time ..... guy ran the trk to work as a daily driver ,the bed was still NEW ! Count me out ....

Yeah but you go "boing!" when you're at that old timey garage and you catch a whiff of that unique odor which can be embarrassing.

Used it as a substitute for kerosine in Ed's Red. Don't know if it adds anything but the mix works really well. And smells good. (No, I don't mean as in the first paragraph.)

I mostly use it for air tools. MMO makes a different oil for air tools but I never buy or use any thing special.
It also works great for tap and die jobs.
