With my OB 1000 km with LPG behind me. The tank was almost gross 66l and should be net at 53l. I drove the tank completely empty now. But when the tank was refueling it was at 47.5 liters. The range was at a consumption of approx. 12.5l at 380km. I am in principle satisfied with the consumption. Only the net volume and therefore the range seems too small. Is that normal? Greeting s
