What did Sea Foam do for your motor?

I also used it on my Vibe GT w 185k miles.

Didn't read the entire thread but anytime a "pour to stall" TEC (top engine cleaner) is used it's thought to be wise to do it at an oil change. You'll never see it on the container but it's generally the way we did GM TEC on early cars IF it was done as a "pour to stall". Is it an issue? I'm sure there's been millions of cars done without.

Pour to stall puts the TEC in the cylinder.

I have used Marvel Mystery oil both poured in the gas tank and into the oil directly, not aware that an oil change would be called for. Having said that, I'll probably listen to FUs advice. Would the fact that it was sprayed in rather than poured make a diff?
