Yes, ~22% ATF in all oil changes.

Tell you what, here is a direct quote right from marvel mystery oil's website itself.

"For example, if your engine has a 5-quart oil capacity, replace one of the quarts with a quart of Marvel Mystery Oil. Repeat at every oil change for optimal performance. Marvel Mystery Oil can be added to engine oil 300 to 500 miles before your next oil change to supplement sludge removal and enhance engine cleaning.
How to use - Marvel Mystery Oil

I repeat, iv'e done this with any brand ATF for decades. Each oil change on all my cars and kids vehicles too. Even on my Audi 5000S and '68 Corvette with IIRC the L88 engine.
Only then, when they would rust out (Chicago rust belt) would I get rid of the vehicle, and even then, their engines had never, never needed any internal work done even up to 331,000+ miles on that engine.

You can lead a many a car owner to water (truth), but you cannot get many to drink (to actually overcome fear and to try something different that works).
