I've use Power Services Diesel Kleen, Howes, 2 stroke, and a number of others. For the last 4-5 years I've been using Diesel Services 4 + in all the diesels. Also every year or two a can of Diesel Purge is run through at 100% til the can is done. Had the injectors done (new tips) in the 13BT least year as well, which made a huge change in the acridness of the exhaust. Biggest change in smoke from the exhaust for the 1HD-T and 13BT thus far was changing from Coop diesel to Petro-Canada diesel.
There are a number of us testing the XP3, though a few will not have much data till a long trip in May. Too soon to report back and it is entirely unscientific, other then fuel mileage as I am tracking my trucks with Fuelly. I want to get a bottle of LubeCorp Premium Diesel Plus at some point and try that as well.
A discussion was going on a while back in the Smoke Thread about cetane and diesel fuel quality in different areas. There are a couple links to interesting discussions on the same topic in TDI forums.

EDIT: Here is a study from 2007 on a number of additives. It is dated, however still interesting. If there are any new reports on line it would be interesting to see them.
