For older diesels like my 300td, regular use of
Diesel Kleen makes a noticeable difference in running and protects the injector pump from the ravages of ULSD. The problem is keeping it in the car and on hand for when I fill up -- it's nasty stuff and the smell permeates the cabin through the bottle!

That stuff really does work well -- just don't do it where the massive smoke will be a problem!
