I have a 2010 GL350 Bluetec...diesel. MB is walking away from the warrantee if I use anything more than 5% biodiesel, claiming it will foul the injectors. Unfortunately, in Illinois, almost all stations are going to 11% biodiesel in the summer, even on the interstates. MB has offered nothing....no direction as to where we should buy #2 diesel, no offer to make an additive, no help whatsoever...simply turning their back on the customer. Anyone with suggestions, or know what BMW,Audi or VW are doing about this?
