Why is the Haval H6 so fuel-consuming?

[OMia]

For the high fuel consumption of the Great Wall Haval H6, you can pay more attention to driving habits. Generally speaking: avoid prolonged engine idling, and try to avoid sudden braking and acceleration. Use high and low gears reasonably and maintain an appropriate driving speed. Additionally, perform regular vehicle maintenance: dirty air filters and oil filters, worn spark plugs, and problematic emission control systems can all increase fuel consumption. Apart from personal driving habits, the following factors may also contribute to the high fuel consumption of the Great Wall Haval H6: 1. Tires: Tires are relatively easy to check, so they should be inspected first. If the tire pressure is insufficient, fuel consumption will increase. If the tire pressure is normal, check the wear level of the tires. Severe tire wear can lead to frequent slipping, which also increases fuel consumption. 2. Engine: If there is a significant buildup of carbon deposits in the engine over a short period, it can also cause high fuel consumption. This situation is likely due to the use of substandard fuel. The solution is to add a certain amount of cleaning agent when refueling. If the effect is not noticeable, it indicates a substantial buildup of carbon deposits in the engine, in which case it is best to take the vehicle to a 4S shop or repair shop for professional cleaning by a technician. 3. Oxygen Sensor: As an internal control unit in the car, the oxygen sensor primarily monitors the fuel-air ratio in the engine. Once it is damaged, it will disrupt the fuel-air ratio, inevitably leading to abnormal increases in fuel consumption. After the oxygen sensor is damaged, the vehicle will emit darker exhaust gases during operation. In this case, the oxygen sensor should be replaced as soon as possible. 4. Faulty Engine Control Unit: Although the electronic control unit (ECU) of the engine is highly reliable, faults may still occur in older vehicles. If one of the control units malfunctions, it may lead to increased fuel consumption, accompanied by poor performance and thick, black exhaust emissions.
