Marvels Mystery Oil Added?

I added a quart of Marvels Mystery Oil to my car so I can keep my engine clean and to help quiet my lifter tick. It has done a great job cleaning it as the tick is barely there anymore. But I recently see my car is kicking up a lot of smoke lately from the exhaust. It is white/gray and I have heard it is from cleaning the engine kind of what SeaFoam does. Has anyone tried this?

I also replaced my PCV valve as well and added an additive to my transmission to help it. I love my car, it is a 2000 Ford Focus with a 2.0L SOHC.

That is residual MMO inside the cylinders that is being burned off with every power stroke of the engine so it's going to smoke for a little while but there's nothing to be alarmed about. Seafoam won't help. If you love it so much, get the engine rebuilt. Additives are pretty much snake oil. Hmm… Why not lash the valves instead of pouring in mystery oil?

What was wrong with the transmission to make you think that an additive would fix it? The Marvel Mystery Oil may have been a mistake. During the middle of the last century cars were not built with as tight of tolerances or for that matter powered by the cleanest of fuels. 15W-50 motor oil and leaded gasoline combined to make a pretty gunky mixture. Old wisdom was to add a can of (insert remedy mixture brand) to help clean out deposits and keep old oil thin.
Your relatively late model vehicle wasn't anticipating this additional ingredient. Chances are that adding 1 quart of MMO to about 4 quarts of oil has thinned it to the point that it is leaking past the piston rings and is being turned into the smoke you're seeing. Hopefully it hasn't caused any permanent damage, but I would definitely recommend an oil change at your earliest convenience.
As far as transmission additives go it's kind of a mixed bag. If the transmission is having issues (like slippage) I have seen some seeming miraculous solutions poured from bottles. However, if your goal is preventative rather than repair I would say stick to the manufactures spec and schedule. 99.9% of the time, that's your best bet. Let's pretend it did something beneficial in the short term, so now is a great time to drain it out and put in fresh synthetic of the correct flavor and a new oil filter.
