What to do if the fuel consumption of Haval H2 is getting higher and higher?
2 Answers
Excessive carbon deposits can roughen the intake pipe walls, affecting the intake efficiency and the quality of the air-fuel mixture, leading to a sharp increase in fuel consumption. It is recommended to clean the carbon deposits every six months. The concentration of the air-fuel mixture in the engine is often too high, which can also increase fuel consumption. If damaged, it will reduce the ignition energy, causing uneven combustion of the air-fuel mixture, resulting in slower acceleration and increased fuel consumption.
My Haval H2 has been running for over three years, and the sudden increase in fuel consumption really worries me. I remember it was only 8 liters per 100km in the city when I first bought it, but now it's over 10. I think the key is to change my driving habits—avoid slamming the accelerator and brakes too often, and maintaining a steady speed of 80-90 km/h on the highway is the most fuel-efficient. Check tire pressure every two weeks; low tire pressure can cause a sharp rise in fuel consumption. Also, regular maintenance is crucial—I change the air filter and engine oil every six months. If neglected for too long, carbon buildup can become severe, forcing the car to burn more fuel. Slow warm-up in winter might also lead to higher fuel consumption, which is normal. Monitor the data recorded by the car app, and if any abnormalities are found, visit the 4S store early to avoid minor issues turning into major expenses.
