Nah. Didn't come up in the search que the first time I tried.

Seafoam is a useful product, it works well on a lot of different stuff!
But it is way expensive for what it is...

It is:
50% mineral oil
20% rubbing alcohol
30% benzine

I've used it to free up rings on outboards and it restored compression to factory specs on a 25 year old motor. I think most people have used it through the brake booster on a car or two.

Not sure I'd put much in the crankcase of the Powerstroke because of the HEUI system. Not really worth putting it in the fuel either. I'd use a good diesel additive.

If your intention was to use SeaFoam as an engine flush, don't waste your money.
Use GUNK "motor flush".
If you've never used it before, pour in two bottles and let your engine run for 10 minutes @1500rpm or less with no load on engine (no driving, turn off AC).
It will dissolve junk and it will be mixed in with the oil, so drain it right away.
Monitor your oil pressure while you are running it with Motor Flush.

If you want to take an extra step, after draining refill with some walmart 10w30 after running that for a 10 minutes drain it, replace oil filter, fill with good diesel oil.
