Hello! I had my first year inspection a few weeks ago. I also had an oil change done, got Mobil1 5W50 and brought with me. After studying various oil and typeR threads here sometimes an ideal choice for the R. In the first week however I had a fuel consumption between 17 and 24 (!!) liters on 100km. My normal average value in urban traffic and mixed otherwise lies at 12.8L. A week later the consumption has calmed down slowly and levelled at 15.4L. That is still 2.6L more consumption than before with the factory oil. Does something go wrong? Defected sensor etc.? Or can the oil really have such a negative influence on the fuel consumption? Since you buy already the best of the best… gruß
