But mixed into the oil...there one has to ask, maybe the oil wasn't the right stuff to being with. MMO can't bring or do anything that a quality motor oil couldn't be doing alone.

For the price of a quart it isn't a painful experiment in any case.
I consider marvel as part solvent, part lubricant. I never put it in my oil except once when I had a stuck valve. I think I put in 50/50 marvel and motor oil, then ran the engine at idle, shut it down, ran it at idle, over and over till the valve freed up... can't remember exactly... I do know that I changed the oil and replaced with 100% motor oil before running under load.

The rear valves/rings don't heat up enough and can get gummed (again, memory may be wrong).

I put it in my fuel for a decade with no ill effects, can't prove it helped, but as I was never attacked by a zombie....
