2012 Great Wall H6 has a comprehensive fuel consumption of 7.2L/100km to 8.5L/100km according to the Ministry of Industry and Information Technology, while the actual fuel consumption ranges from 8.6L/100km to 9.8L/100km. The following factors affect fuel consumption: 1. Environment and road conditions: Low temperatures cause the vehicle to take longer to warm up the engine, leading to higher fuel consumption. Actual user vehicle conditions vary greatly, with road surface and slope, dryness or wetness, curves, and mountainous roads all affecting actual fuel consumption. 2. Driving conditions: Driving conditions have the greatest impact on fuel consumption. Frequent city driving results in higher fuel consumption; normal highway driving leads to lower fuel consumption; frequent short trips mean the vehicle operates at ideal temperatures for relatively less time, also increasing fuel consumption. 3. Number of passengers or cargo weight: Vehicle weight has a significant impact on fuel consumption. When carrying more passengers or a fully loaded trunk, fuel consumption inevitably increases. Therefore, minimizing unnecessary items in the vehicle can save fuel.

Driving a 2012 Great Wall H6 for over a decade, I find its urban fuel consumption generally ranges between 9 to 10 liters per 100 km. During peak traffic congestion, it can rise above 11 liters, but drops back to 7-8 liters on highways, which is quite decent. Many factors affect fuel efficiency—for instance, driving habits: my smooth acceleration and minimal braking save significantly more fuel compared to my friend's aggressive throttle inputs. Road conditions matter greatly too; frequent stops at city traffic lights increase consumption. With an aging vehicle, regular maintenance is essential—after replacing the air filter and spark plugs last time, fuel economy stabilized somewhat. Maintaining proper tire pressure reduces rolling resistance, saving 1-2 liters. Though older cars tend to be thirstier, their simple maintenance and low costs make them surprisingly satisfying once adapted to.

I use a 2012 H6 for my daily commute, with an average city fuel consumption of around 10 liters. During peak traffic jams, it spikes to 12 liters, while cruising on the highway drops it to 7 liters—driving habits make a huge difference. I always decelerate steadily, brake gently, and avoid sudden stops. Complex road conditions add to the trouble, with frequent starts and stops causing fuel consumption to soar. Older cars require careful maintenance; last year, I had the fuel injectors checked and the throttle body cleaned, which improved efficiency and lowered fuel consumption. With fuel prices high now, monthly expenses are steep, so I’m considering adding a tire pressure monitoring system or switching to low-viscosity oil for better economy. Opening windows on the highway increases drag, while using the AC with windows closed is actually more fuel-efficient. I’ve adapted to the old car’s rhythm—though its fuel consumption is high, it’s reliable and durable.

Driving a 2012 H6, fuel consumption was found to be 9L in the city and 7L on the highway. Driving habits are the main factor, with rapid acceleration consuming more fuel and gentle pressing saving fuel. Complex road conditions such as numerous traffic lights in urban areas lead to higher fuel consumption. Aging vehicles with dirty fuel injectors and old spark plugs need timely replacement. Closing windows on the highway reduces air resistance, and maintaining a steady speed of 80 km/h is economical. A clean air filter can increase efficiency. Older cars are not as fuel-efficient as newer models but are simpler and cheaper to maintain, with monthly maintenance keeping fuel consumption under control.
