How many kilometers can a Haval Big Dog run on a full tank of gas?

[McAlaina]

Haval Big Dog can run 318 kilometers on a full tank of gas. Solutions for high fuel consumption: 1. Clean engine carbon deposits: Excessive engine carbon buildup is a major cause, primarily due to the use of unsuitable fuel. It is recommended to add a certain amount of fuel cleaner when refueling. If the effect is not obvious, it indicates significant carbon deposits in the engine. In this case, the car must be taken to a 4S store for professional cleaning of the engine carbon deposits by technicians. 2. Check the oxygen sensor: As an internal control unit of the car, the oxygen sensor mainly monitors the fuel-air ratio in the engine. Once it is damaged, it will cause an imbalance in the fuel-air ratio, leading to a sudden increase in fuel consumption. After the oxygen sensor is damaged, the exhaust pipe will emit darker-colored exhaust gases while driving. At this point, the oxygen sensor should be replaced.
