Hot Shots products are a must for all diesel owners.

Ended up not needing this for my injectors after I yanked some fools ts6 chip, but man it really brought my piston rings around in my 7.3, have almost no blow by now!Also tried in friends 7.3 with injector issues, did a run without, low power and engine light came on under load, maybe a little low on oil, then put the whole bottle in and immediately more power, no more engine light, and kept clearing up as we drove it.Still will have to re-oring his injectors at the least as its burning oil, if not replace or full rebuild, but it'll clear up the sludge in your engine bigtime, and fix stiction in many different places.Worth it totally.
