The Tuguan fuel gauge shows that the car can still drive about 20km at 0.
The oil lamp lights up when the fuel gauge shows 0 km, which is just a warning to refuel. In fact, there is still oil in the fuel tank. It is basically OK for ordinary family cars to run at least another 20 or 30 km. But how far it can go depends on the specific model. After all, the fuel tank size, fuel consumption and settings of each model are different. In the city, it is totally OK to stick to the nearest gas station.
