Should I use Sea Foam?

seafoam on diesels isn't something I would use, my 95 F350 7.3 turbo diesel has 305k miles and no additives used on it and my John Deere 430 with 2k hours runs mint with no additives.

I would never add seafoam to the oil

 

The tractor had +20,000 hours and would run on all 3 cylinders only if sea foam was used.

 

Careful doing it through a vacuum line to clean the throttle body, I remember a dude on the Yotatech forum back in the day hydrolocked his motor using the stuff. There's a reason they say to have a "professional" do it that way on the bottle.

I'm not a professional and I've done it that way myself, works really well. Just don't be a dunce and pour it too quickly, have to do it slowly. And yeah, your truck will be blowing fog out the tailpipe for a solid 10 minutes afterward lol.

 

I laughed when a buddy poured it into his boat engine carb too fast and blew a head gasket
