Has to be a legitimate reason you would think of adding some type of cleaner to the oil, like a sticky lift or stuck ring, not general maintenance IMO. And, it's usually either a last resort or hail-mary. You can get lucky though.

ATF does have heavy detergents in it, so it does make sense, and it can work in some instances. But never use all ATF.

Oil additive packages are much better these days, and there isn't the same type of 'Quaker State' buildup as in the past. A lot of it is the additives, but poor change intervals and overheating, that plays a big part in buildup.

A-chunk-o-sumthin hanging a lifter or ring, that I understand attempting a hail-mary fix, like I said, you can get lucky, and have personally had luck with lifters.

MMO is basically a detergent additive package, so in theory, it won't really do any 'harm', but if it helps, I think it's base on a number of factors, and again will just say you might get lucky.

Now atf mixed with water, trickled down a carb while working the throttle, that can help with buildups and sticky valves. It's part of the basis of the MMO product success, can do crank case and/or in gas.

Still, I think most of the 'mystery' of any of the 'magic in a bottle' stuff is hype. Marketing. And targets consumers that aren't 'automotive savvy'.

It is cool though, and always gives me a chuckle, when I see people doing seafoam in an apartment/townhouse complex, on an import with a fart-can exhaust, fogging the whole area.
