What are the reasons for high car fuel consumption?

Introduction to the reasons for high car fuel consumption: 1. If you notice a significant decrease in the current coasting distance while driving, you should check whether the tire pressure meets the standard. Insufficient tire inflation will also increase fuel consumption. 2. Check the degree of tire wear. If the tires are severely worn, slipping will often occur, increasing fuel consumption. 3. If you hear abnormal noises from the wheels while driving or starting, promptly check whether there are faults in the bearings or braking system. If the wheels do not rotate normally, it will affect the speed and increase fuel consumption. 4. Clutch slipping will cause the engine to lose RPM. If you notice the engine tachometer increasing rapidly during hard acceleration but the vehicle speed increases very slowly, you can determine that the clutch is slipping. 5. When the car has traveled 200,000 to 300,000 kilometers, insufficient cylinder pressure usually occurs, and fuel consumption will increase significantly at this time. 6. If the spark plugs have been used for too long, fuel consumption will also increase. Damaged spark plugs will reduce ignition energy, slow down acceleration, and lead to a noticeable increase in gasoline consumption. 7. When the car's temperature control switch and thermostat are damaged, fuel consumption will increase. This is because damaged temperature control switches and thermostats will lower the water temperature, preventing the carburetor from working properly and leading to poor gasoline atomization.
Having driven for over a decade, I've noticed that high fuel consumption is often due to poor driving habits. For example, accelerating aggressively to overtake right after hitting the road, stomping on the gas pedal hard, and braking frequently all put a heavy load on the engine, burning fuel quickly. On the other hand, smooth starts and maintaining a steady speed save a lot of fuel. Another factor is blasting the air conditioning on and off, especially in summer, as the cooling system increases engine load, naturally raising fuel consumption. When parked and waiting, avoid idling the engine for too long—it's just wasting fuel. I recommend developing gentle driving habits: less sudden braking and hard acceleration can save a significant amount of money. Regularly checking tire pressure is also crucial; underinflated tires increase rolling resistance, which also wastes fuel. Overall, driving technique is the main factor, and small changes can effectively reduce fuel consumption.
