A member on another Mercedes forum, where I posted the same question provided a link where the characteristics of the new Diesel fuel are described.

http://chevron.com/products/prodserv/fuels/diesel/faq.shtml

I just read that link and this does not sound good at all, especially the section where Chevron states that there is a good chance that rubber seals throughout the injection system may dry up and start leaking. Apparently lubricity IS NOT the problem, but dried out "O" rings and seals are. Chevron also state that fuel additives will not help.

This is not good.
