Hello Porsche9,
no, every of the listed fuels is unleaded today. Since 1988 leaded fuels are forbidden in Germany. Unleaded fuels were introduced in 1984. Ethanol added fuels E5 (5%) and E10 (10%) were introduced around 2009.
Normal 91ROZ and Super 95ROZ always has 5% ethanol over here. There is also Super 95ROZ with 10% Ethanol available. That is called E10.
There is also E85 available. Which means 85% ethanol. But you need an engine and fuel system that is modified for that kind of fuel.
Regards, Markus
