Well, I guess I'm lucky with a 2003 so I don't have to be as concerned as those of you with the newer models. I'll continue to use PS and keep looking for the right answer, if there is any.
Here are 2 web sites to check out.
www.palatineoil.com/fuels.html is a local Marathon distributor.

Q. Do I need to put an additive in my fuel tank to replace the lubricity that was provided by the higher sulfur content?
A. Like Low Sulfur Diesel fuel, ULSD fuel requires good lubricity and corrosion inhibitors to prevent unacceptable engine wear. As necessary, additives to increase lubricity and to inhibit corrosion are added to ULSD fuel prior to its retail sale. With these additives, ULSD fuel is expected to perform as well as Low Sulfur Diesel fuel.
Q. What are the penalties for failing to comply with EPA's ULSD fuel standards?
A. The EPA standards provide strong incentives for suppliers to provide the proper ULSD fuel formulation. Civil penalties of up to $32,500 per violation per day can be assessed for non-compliance with EPA’s ULSD fuel standards, or for misrepresentation of the sulfur level of diesel fuel.
