Marvel Mystery Oil works best if you have a Marvel Carburetor.

Guten Abend Katy, Sconnors, Flathad und alle Mitleser,
ATF (automatic transmission fluid) is highly unsuitable for internal combustion engines. This is because it is specifically a transmission fluid, and the additive packages used in transmission fluids differ significantly from those in engine oils.
Transmission fluids contain a high proportion of extreme-pressure additives designed to withstand the intense forces exerted on helical gears. Their corrosion-protection chemistry is also different; while it does not need to endure the combustion process itself, the additives are formulated to remain effective for >100,000 miles.
Engine oils, by contrast, contain wear-inhibiting and detergent additive packages that do not leave significant deposits during combustion. Furthermore, they utilize specific corrosion inhibitors designed to neutralize the harmful acids generated during the combustion process.
Moreover, the additives found in transmission fluid will contaminate the engine oil.
Sconnors - How many miles have you driven using automatic transmission fluid so far, and what is the residue amount condition of the piston crowns, as well as the stems and tulip-shaped heads of the exhaust valves?
If you prefer not to use Marvel's Mystery Oil, a compromise would be to use a modern two-stroke oil that meets the API "TC" or ISO "L-EGD" classification.
Flathead, in Europe, MMO has been "prohibited" for some time due to the presence of certain concerning ingredients. Obtaining EU/REACH approval would be prohibitively expensive, especially since the product now serves only as a niche item for classic cars. It must not be used in modern engines, as it can impair the function of particulate filters and catalytic converters.
