I don't think I'd do it if I had a catalyst to worry about, so that would tend to exclude modern engines, at least where emissions are tested.
If they aren't I suppose you could ignore or eliminate the catalyst.
Not my thing either. However, oil is simply a hydrocarbon, in very small quantities, it is easily handled by modern catalysts. An oil's additives could be another matter, depending on choice of oil. Marvel Mystery Oil does not seem to harm catalysts, and I do not recall any restrictions for modern vehicles on it's packaging. It might simply be less risky to use MMO if some additional lubricity is desired.
FWIW, TCW-III is a very effective lubricity additive for diesel fuels. Bringing the HFRR numbers of Jet-A from the high 600's all the way down to 255. A huge improvement.
And, modern gasoline does contain traces of oil and other friction modifiers.
