Has anyone left seafoam in their engine for a couple of hours before burning it out, instead of 15-20 minutes? Is this inadvisable? Talked to a guy who said he always let his seafoam treatment sit for hours.
I would think after a couple hours it would leak down into the oil.
i put seafoam straight in my oil if you were commenting on that being bad, but i think he may have just been saying were the seafoam would go
Is is bad that I recognized the engine in the video as an escort engine before I even played the video?
