I googled it, watched vids on youtube, and searched the forums here- but I'm still not so sure about pouring seafoam in my powerstroke.

Can someone talk me into it or more importantly, out of it?

 

NOT in the oil. If you want to pour it in the fuel then thats fine.

 

I've ran it in the oil for about 100 miles before the oil change.
Didn't hurt anything.

If you look at any of their info, it will say to do it just before you change the oil.

I've ran it at the start with my gasser, but I don't think i'd do it in my powerstroke, but it did get things cleaned out nice.

Lot more oil in our trucks too, so its really diluted compared to the 6 qt's you put in a gas engine.

Mostly At your own risk sorta deal. But, if I was to give anyone any advice on doing it, put it in a few days before an oil change and just make sure its being driven, not sitting until the oil change.
