Moin in the round, I had read here on MT last week a fairly well-founded contribution to E-10 which took me many worries and after checking again the compatibility for my engine decided to test it just once for a tank filling. The tank was almost empty and so the E-10 immediately came to the effect unmixed: IT WAS A DIFFERENT! I always got angry about the rough run of the 1.8er and that was suddenly gone. The engine runs quieter and quieter. Or did I succumb to a placebo effect here? I have always fueled SUPER+ or even ULTIMATE so far, but didn’t feel any improvement and now rather unconsciously registered the change after starting… Did I want to put in the room like this… Greeting KK
