Redline 85 Plus and DFC are identical.

I run 85Plus in every tank, and have owned my 300D for about 8,000 miles, all of which have been aggressively driven. At this point, I NEVER see any smoke from this car, at all, no matter what. Period.

Guess I got rid of the carbon, because it used to smoke a bit, but not a lot.
