What are the reasons for the high fuel consumption of the Max?
2 Answers
The reasons for excessive fuel consumption include: 1. Lack of maintenance: The vehicle has not been maintained for a long time, and the engine oil and air filter have become dirty, leading to increased fuel consumption. 2. Aging: The engine spark plugs are aging, and excessive carbon buildup affects the ignition effect, resulting in high fuel consumption. 3. Insufficient tire pressure: Low tire pressure increases the contact area between the tires and the ground, increasing friction and driving resistance, which raises fuel consumption. 4. Excessive carbon buildup: Carbon deposits can accumulate in the throttle valve, fuel injector, intake tract, and piston top. Excessive carbon buildup in any of these areas can lead to incomplete combustion, thereby increasing fuel consumption.
Recently, I've noticed that the fuel consumption of my S-MAX has increased significantly. Upon reflection, it might be due to my driving habits. For instance, on the highway, I always feel the urge to overtake, and when the speed goes up, the fuel just drains away. In city traffic, frequent sudden starts and stops make the engine work unevenly, consuming more fuel. Prolonged use of air conditioning in summer or carrying heavy loads, like during family trips or hauling goods, naturally increases the vehicle's weight and fuel consumption. Additionally, the tire pressure was a bit low, and I didn't inflate them in time, leading to higher rolling resistance and a spike in fuel consumption. A check-up at the repair shop revealed that the air filter was clogged and dirty, and the technician said the engine wasn't breathing properly, causing it to burn more fuel. The spark plugs were also worn out, leading to incomplete combustion and wasted fuel. Now, I'm learning to accelerate gradually and brake gently, planning routes to avoid congestion, and my fuel consumption has finally decreased a bit. Saving money also means fewer trips to the gas station. Regular maintenance, like changing the air filter and cleaning carbon deposits, is really crucial and shouldn't be delayed.
