Hello, I drive a Golf IV 1.6. Normal almost continuously with E10. Mostly I refuel at a free petrol station in our place. From time to time at Aral. Up to now I have never actually filled with Shell. Until 2 weeks ago and since then my car needs extremely little fuel. Can this be related to the fact that I have Shell petrol in the tank? Or are these just different circumstances and the whole thing happens? Have you ever had similar experiences? Greetings, Alex
