Why does 12 Land Rover Range Rover Premium Edition waste so much oil?

1, the throttle valve does not match the engine control unit after cleaning or the matching is unsuccessful.

2, the engine electronic control system failure, resulting in the mixture is too rich.

3. The engine ignition coil or spark plug is damaged, and the fuel injector leaks oil, resulting in an increase in fuel consumption.

4, engine cooling system failure, resulting in engine temperature is too low, has been in a warm-up state.
