I have tried using both DFC and 85+ in my 300D, and I used to run DFC in my old 300SD. I have done some reading on the Redline website, and the only differences that I can discern are that the 85+ contains more cetane while the DFC contains smoke suppressors.

Are there any other differences in the two products? It is time to order some more (from PartsShop of course), and I'm not sure what I should buy. Which would be more beneficial for my 91 300D?
