What are the reasons for the high fuel consumption of Dongfeng 580?

There are three main reasons for the high fuel consumption of Dongfeng 580. The following is a detailed introduction to these three reasons: 1. Abnormal tire pressure: If it is found that the vehicle's coasting distance is significantly shortened during driving, the tire pressure should be checked to see if it meets the standard. If the tires are underinflated, fuel consumption will also increase. The tires should be properly inflated in time. 2. Tire wear: Check the degree of tire wear. If the tires are severely worn, slipping will frequently occur, increasing fuel consumption. New tires should be replaced when necessary. 3. Bearings and braking system: If abnormal noises are found in the wheels during driving or starting, the bearings and braking system should be checked for faults in time. If the wheel rotation is abnormal, it will affect the speed and increase fuel consumption.
Driving the Dongfeng 580 feels like it consumes a lot of fuel, and for me, it's often a matter of driving habits. I enjoy driving fast in the city, frequently accelerating and decelerating, and when I press the throttle a bit harder, the fuel consumption shoots up. It's better when driving steadily on the highway, but in congested areas with stop-and-go traffic, it's too fuel-consuming. Using the air conditioning or driving with the windows down also increases air resistance, making the car work harder. I suggest trying gentle driving, avoiding sudden braking and hard acceleration, and using cruise control if the car has this feature. Tire pressure should also be checked regularly, as values below the standard can cause slippage and increase fuel consumption. Regularly changing the air filter and engine oil can help the engine run more smoothly. Carrying too much load isn't good either, so avoid keeping unnecessary items in the car. Overall, adjusting these small details can save a lot on fuel costs.
I think the high fuel consumption of the Dongfeng 580 is often due to inadequate maintenance. A dirty air filter means the engine can't get enough air, so it has to inject more fuel; old engine oil with poor lubrication also reduces efficiency; low tire pressure increases rolling resistance and consumes more fuel. I check the spark plugs and throttle body every six months—excessive carbon buildup leads to poor ignition and wasted fuel. Cleaning the fuel injectors is also crucial, as clogged injectors cause uneven fuel spray and a spike in consumption. Poor urban road conditions or heavy loads like using the AC are contributing factors, but regular maintenance is key to minimizing losses. I recommend replacing the air filter every 10,000 km and the engine oil every 5,000 km to keep the system clean and the engine running efficiently. In practice, this makes the fuel gauge drop much slower.
