Does anybody have experience with the use of BioDiesel Fuel in mid 80's Mercedes, esp '84 300SD type engines (mine). I understand that this type of fuel is common in Europe. I have heard that a 20/80 bio/normal is ok in "anything". Any experience with higher blends would be helpful.
If only fuel lines were in question I would have no problem changing those. My biggest concern is what rubber or other non compatible components might be hidden in EXPENSIVE places like the injector pump.
