I've been using a combination of Power Service and WalMart 2cycle for about 6 years in my VW Rabbits. I consider the 2cycle is for lubricity at the IP and the Power Service is for performance and injectors. The only reason I'm using Power Service is because I picked up several gallons at a garage sale!
With super low sulphur diesel- I think that the lubricity issue is significant for our Injection Pumps. Now that I have a 6.9L Navistar, I'm using the same approach. I've also heard and believe that Marvel Mystery Oil is a good fuel additive but it isn't cheap.
Gotta watch the red stuff in your fuel. From what I have heard, if they "stick" your tank and it shows red, it is up to you to prove your innocence. Apparently, just having red in your tank proves your guilt!
