OK, back to the original question...has anybody (besides Willie) used Biodiesel in a 2005-2006 W211 CDI? MBUSA has approved B5 in these cars as of June 8, 2006.

Any improvement or reduction in mileage and/or performance?

I may be able to find out what the answer is by Monday night. I'll also try to find out what will happen if a more Bio rich mixture is used.

At this point, I only know that current higher sulfer content fuel may clog the emisions equipment in the '07's.
