Seafoam is great for cleaning any system on a vehicle. It gets expensive if you decide to run a few cans (always recommended), but walmart has a cheaper version of the same stuff.
I've only used marvel mystery oil on air tools. I've never heard of it being used where you'd mix it with other fluids. I can see it being helpful in the cylinder like you did but I don't know about the oil or fuel system.
