Marvel Mystery Oil?

[40th GT]

How does this stuff compare to Seafoam? The local Autozone didn't have the Seafoam in stock so I picked up some of this..Can I run this stuff through the PCV like I would with Seafoam?

no i believe it goes in the crankcase

Yeah, the bottle says to use it either in the gas tank or crankcase, or both but I wanted to ask because it seemed similar to Seafoam.

yes marvel mystery oil goes in the crankcase. nothing like seafoam.

I wouldn't put anything in my engine with the word "mystery" in the title.. just superstition I guess. Besides man, you got an '04.. it can't be to the point of needing additives yet, can it?
