How about the fuel consumption and maintenance of the Great Wall Xuandong automatic transmission? Please give me some advice.

Hello, I want to check whether it costs oil. First, when idling, see if the exhaust pipe is out of water. If there is no water, it proves that it is fully burned. On the contrary, the combustion is not sufficient. Second, in the case of insufficient combustion, check whether the throttle, spark plug and fuel injector are not smooth in oil circuit and lack of cylinder leads to insufficient combustion, resulting in fuel consumption.

Automatic transmission, the general fuel consumption is relatively high, especially domestic automatic transmission like this, the price is low and the gearbox matching is too simple. It is recommended that the owner go to a professional 4S shop for testing.
