How to Deal with High Fuel Consumption?

To address high fuel consumption, it's essential to first understand its causes. The related explanations are as follows: 1. Driver's skill level: Unreasonable gear shifting and excessive braking during driving artificially increase engine power loss. Additionally, frequent braking leads to more starts, as the fuel consumption rate is very high during starting. Low-temperature driving: The engine is designed to operate at normal temperatures (80°C to 90°C). If the car is driven without preheating after starting, the engine remains at a low temperature, resulting in poor atomization of the air-fuel mixture and incomplete combustion. 2. Engine technical condition: The fuel level in the carburetor float chamber is too high; the air filter is excessively dirty, or the carburetor air jets are clogged; the carburetor fuel jets have been enlarged by fuel erosion over long-term use; the idle speed is adjusted too high; the semi-horizontal hole in the float chamber is blocked, causing siphoning, etc.

To address fuel consumption issues, I start with the basic condition of the car. If you notice a sudden increase in fuel consumption during normal driving, pay attention to the engine's condition. Common problems like carbon buildup on spark plugs or a clogged air filter can lead to incomplete fuel combustion, wasting gasoline unnecessarily. I recommend regularly inspecting these components—replace the air filter every six months and try changing the spark plugs every 50,000 kilometers. Tire pressure is also crucial; I've seen many car owners overlook this. Soft tires increase rolling resistance, leading to higher fuel consumption. It's best to buy a tire pressure gauge and check weekly, adjusting to the recommended value. Additionally, poor-quality engine oil increases internal friction—switching to full synthetic oil can make a noticeable difference. Don’t forget, driving habits are key—sudden acceleration and braking consume more fuel. Develop smooth starts and maintain steady speeds, using cruise control on highways. Finally, if the issue persists, visit a professional shop to check the oxygen sensor or fuel system to prevent minor problems from escalating.

I find dealing with high fuel consumption quite straightforward, starting with adjusting my driving habits. Through experience, I've learned that aggressive acceleration from a standstill and sudden braking consume the most fuel. On city roads, I try to anticipate traffic lights and slow down in advance to coast and save fuel. Additionally, carrying too much weight in the car isn't cost-effective, so I avoid cluttering the trunk with unnecessary items and regularly clean it out to reduce weight. Another key point is tire maintenance; I've noticed that low tire pressure can increase fuel consumption by up to 10%, so I use a manual pump to check tire pressure weekly and inflate them to the recommended level. If the air filter gets dirty, I replace it promptly—buying parts and replacing them myself is quite convenient, with plenty of tutorials available online. Regarding engine oil, switching to a lower viscosity type can help reduce resistance. On long trips, using the air conditioner significantly increases fuel consumption, so on hot days, I first open the windows for ventilation before turning on the AC. Regular maintenance is essential; I never skip changing the oil and checking the system every 5,000 kilometers. These small habits, when accumulated, make a noticeable difference in fuel efficiency.

Fuel consumption can be primarily addressed through driving habits and maintenance. I usually focus on smooth acceleration and avoid sudden throttle inputs; maintaining a speed of 40-60 km/h in the city is most fuel-efficient. Regular maintenance includes checking the air filter and spark plugs, replacing them if clogged or worn out. Don't overlook tire pressure either; checking it monthly and adjusting to the standard value can save a significant amount of fuel. Cleaning out the trunk to reduce weight helps lighten the load. If fuel consumption issues persist, it's advisable to visit a professional shop to diagnose potential oxygen sensor malfunctions. These methods are simple, practical, cost-effective, and environmentally friendly.
