My friend has an '07 E320 with the Bluetec, and put a tank of B100 in it. Not many miles later, it was suffering from a lack of power. I changed the fuel filter on the engine, and he filled the remainder of the tank with pump diesel. The car ran much better, but lacks a little power after several miles of driving. I drove it around this weekend (he went away, and asked me to put some miles on it for him), and put eight gallons of diesel in it. It seems to be about 80% now. I am wondering if there is another fuel filter other than the main filter located in the "V" of the engine?
