What is the actual fuel consumption of the Mengshi?
3 Answers
Dongfeng Mengshi has an average fuel consumption of 11.3L per 100 kilometers. The specific fuel consumption standard should be based on actual usage, as fuel consumption is related to multiple factors such as load, hill climbing, air conditioning usage, and low tire pressure. This model is equipped with a 6.5-ton engine, which results in relatively high fuel consumption. Common reasons for fuel consumption and solutions are as follows: Strengthen vehicle maintenance. The adjustment and maintenance of the vehicle affect engine performance and driving resistance. Statistics show that poorly maintained engines can increase fuel consumption by 10% to 20%. Owners should regularly perform routine maintenance at auto repair shops, such as checking tire pressure, wheel alignment, adjusting brake pad and drum clearance, lubricating chassis points, changing oil on schedule, and inspecting filters. Every vehicle has its optimal fuel-efficient speed, which is generally around 70-90 km/h for sedans (varies by model). High-speed driving significantly increases resistance (mainly air resistance). Proper refueling. Using higher-octane fuel is not always better. When the fuel grade is too high or too low, incomplete combustion may occur, leading to higher fuel consumption, unstable engine operation, or even damage to the engine and other critical components.
As a large off-road vehicle, the Menghshi does consume significantly more fuel than regular cars. Based on my experience driving it for a while, the actual fuel consumption largely depends on road conditions and driving habits. In city traffic jams, it can easily reach 18-20L/100km, while maintaining steady speed on highways may bring it down to around 14L. Frequent off-roading or mountain driving consumes even more, potentially exceeding 22L. I recommend avoiding aggressive starts, accelerating gently, maintaining proper tire pressure, and being aware that AC usage in summer increases consumption. Don't believe the low fuel consumption claims - in reality, it burns through fuel rapidly, requiring frequent gas station visits. Using higher quality engine oil and fuel additives might slightly improve the numbers, but don't expect significant savings. Overall, it's designed for off-road performance, and enjoying its capabilities comes with this fuel-guzzling cost. Using an app to track driving data is advisable for accurately monitoring actual expenses.
After several family trips with the Mengshi, I found the actual fuel consumption really tests the budget. For daily city commuting, it's basically 18 to 20L per 100km, while highway long-distance driving is slightly more economical at around 15L. However, it immediately jumps to 25L when encountering uphill roads or heavy loads. The fuel tank is large, but each refueling is painful—I have to plan my trips carefully to avoid running out of fuel midway. The main reasons are the heavy body and powerful engine. I've tried gentle driving without rushing to overtake, which can save fuel down to 16L. Turning on the AC in hot weather adds about 1L. Rapid tire wear also affects fuel consumption, so regular checks are recommended, and tire pressure shouldn’t be too low in winter. In short, don’t choose this vehicle for fuel economy—prioritize safety and functionality, and treat fuel costs as entertainment expenses. Recording mileage will give you an accurate idea of the real consumption level.
