Hello guys, today SuperPlus has been filling up and imagining that the car is pulling better. I read in the BMW forum that the modern motors with electronics (dynamic knock control or something like that) offer more power and torque with better fuel. Is that true or is that just my idea? How is your experience on this topic? Furthermore, I have the feeling that the engine sounds particularly rough when I am fuelled by jet and noticeably softer when I am fuelled by Aral… have you made similar observations???
