How to Solve the High Fuel Consumption of 12L/100km for Haval H6?

Here are the solutions for the high fuel consumption of 12L/100km for Haval H6: 1. Fully synthetic engine oil: Switch to a branded fully synthetic engine oil. 2. Shift gears according to speed in urban areas: Start in 2nd gear, shift to 3rd gear at 15-20 km/h, 4th gear at 30-35 km/h, 5th gear at 50 km/h, and 6th gear when exceeding 65 km/h. 3. Throttle control: Apply the accelerator pedal gently. 4. Reduce vehicle weight: Try to minimize the vehicle's weight. Always fill up the fuel tank completely, as excessive air in the tank for a long time can lead to gum formation. Below are some additional details about the Haval H6: 1. Body dimensions: The Haval H6 measures 4653mm in length, 1886mm in width, and 1730mm in height, with a wheelbase of 2738mm. 2. Powertrain: It is equipped with a 7-speed dual-clutch transmission, delivering a maximum horsepower of 169. The vehicle has a maximum power output of 124 kW, with front-wheel drive. The front suspension is a MacPherson strut independent suspension, and the rear suspension is a multi-link independent suspension. The tire specification is 225/60R18.

A fuel consumption of 12 is indeed a bit high, as the normal range for a Haval H6 is around 8-10. Having driven a Haval for several years, I found that aggressive driving habits are the main cause. Gentle acceleration is key—avoid sudden acceleration or hard braking, and maintain a steady speed between 60-80 km/h for optimal fuel efficiency. Additionally, tire pressure below the standard value increases friction loss, so it's recommended to check tire pressure every two weeks. A dirty air filter also affects intake efficiency, and replacing it annually can improve combustion. Furthermore, avoid prolonged idling with the AC on, as this can significantly reduce fuel consumption. Making these small daily adjustments can greatly improve overall fuel efficiency. Developing good habits is more effective than anything else.

The high fuel consumption of 12L/100km for the Haval H6 might be related to vehicle maintenance. If the car is driven frequently without proper maintenance, spark plugs can accumulate carbon deposits, leading to incomplete combustion—try replacing them with new ones. Thick engine oil can also increase engine resistance; switching to lighter synthetic oil is better. Worn tires or misalignment can also increase fuel consumption, so ensure tire rotation and balancing during each maintenance. Frequent use of air conditioning increases load—reduce usage or lower fan speed in hot weather. From my experience, regularly cleaning engine bay dust and adding fuel system cleaners naturally lowers fuel consumption. If all else fails, take it to a repair shop for a full inspection—it saves time and effort.

A fuel consumption of 12L/100km isn't uncommon, but if a new car shows this, it's worth paying attention to driving habits. Check if there's excessive cargo adding weight, and remove rarely used items. Ensure tire pressure is at the manufacturer's recommended level (typically 2.2-2.5bar for Haval H6) and refill immediately if low. Using air conditioning increases fuel consumption by about 10%, so close windows when possible to reduce drag. I usually avoid frequent stops and starts in urban areas, opting for smooth routes or highways to balance consumption. Also, avoid aggressive starts; maintaining steady speeds is far better than constant braking. Simple adjustments can significantly reduce fuel usage.
