Does the new Passat hot air conditioner consume oil?

Accurately speaking, turning on the air conditioner does not require the engine to consume extra power, but only transfers the normal engine heat to the carriage, but the operation of the blower needs electric energy, and the use of these electric energy will have a certain impact on the generator, thus increasing the load of the engine, but this load is negligible for the engine, basically negligible. If you want to take this load into account, then I can suggest that you raise the temperature, turn off the blower, put the air conditioner on the external circulation and let the cold air outside enter the car through the radiator at the speed of the car. If the fuel consumption is too high, you'd better put all spare tires, tools and cushions in the garage and go to the toilet before driving. Hehehe, just kidding.
