I once killed a ford 300, listened to a friend and did the mystery oil thing and ended up with a serious rod knock.

get the stuff out! run some 30 weight and run it a little and change the oil again.

Marvel Mystery Oil is "Top end lubricant" fuel additive, mainly for diesel engines. It's been 25 years since I've read the label but I don't remember anything about putting in your crankcase.
