Hello in the round, My r172 would have to be based on the 204 it platform which I could drive with 220 CDI on average on 5 liters. I now have the first 250 km behind us and watch the speed, which always moves nicely close to the 1000 rpm. The car has just over 6000 km and the average is shown to me with over 6 liters of diesel. The transmission is learningable and the engine was driven last year only 6000 km. Is there anything else?
