Hi
When you can get it cheap go for Shell VPower Racing oder Aral Ultimate (both 100 Octane)
Or just take "Super Benzin" (95 Octane) like Shell Fuel Save Super for Example....
But you have to watch out .... since a few month the coverment is trying to sell us Super E10 (E10 means 10% bioethanol)
Our engine is E10 ready but it simply sucks ....
Less Power and a higher fuel consumption.....
Only thing about it: It´s 10% biological.....
Hate this crab like 75% of all Germans so it stays in the Gas stations
