Why does a used Beidou Xing consume more fuel?

[AlainaRose]

Factors affecting car fuel consumption are as follows: 1. Displacement: The engine displacement has a certain impact on the car's fuel consumption, but this impact is a fixed value. 2. Tire pressure: The car's fuel consumption is also directly related to tire pressure. When the tire pressure is too high or too low, the car's fuel consumption will increase. 3. Road conditions: The road conditions on which the car is driven also affect fuel consumption. 4. Combined fuel consumption: This is calculated by dividing the total emissions from both urban and suburban driving cycles by the total mileage completed in these two cycles, and then using the emissions to calculate the corresponding fuel consumption value.

I used to drive a second-hand Beidou Star, and its high fuel consumption was a real headache, mainly due to the aging of the vehicle. Severe carbon buildup inside the engine, such as worn piston rings and valves, reduced combustion efficiency, leading to fuel wastage. Clogged air filters were also common, and insufficient air intake increased the engine's workload. Additionally, aging spark plugs caused inaccurate ignition, requiring frequent checks and replacements. If the tire pressure was too low, driving resistance increased, especially when carrying heavy loads, which made the car even more fuel-intensive. I recommend first replacing the air filter and spark plugs, as regular maintenance can effectively improve fuel efficiency. Even if the car is old, proper maintenance can keep it running smoothly—at least it saves you money and hassle in the long run.

When I bought a used Suzuki Alto, I noticed the fuel consumption was too high. After driving it for a while, I realized the previous owner didn't maintain it properly. Infrequent oil changes caused the engine internals to become sticky, leading to poor operation. Driving habits also played a role, such as sudden acceleration or frequent stop-and-go in traffic, which can cause fuel consumption to skyrocket. Additionally, the oxygen sensor on the car might be faulty, sending incorrect signals and resulting in an overly rich fuel mixture. I tried adjusting my driving style—gentle starts and steady cruising—and the fuel consumption dropped significantly. Checking whether the tire pressure is normal is something I can easily handle myself; it's better not to rely too much on repair shops.

High fuel consumption in a used Suzuki Wagon R is usually caused by mechanical issues. Engine components such as carbon buildup in the fuel injectors can lead to inaccurate fuel injection. Blockages in the air intake system restrict airflow, affecting combustion efficiency. Oxygen sensor failure is common in older vehicles, where incorrect readings result in excessively rich fuel supply. Low tire pressure increases rolling resistance and also wastes fuel. I recommend using simple tools to check tire pressure and replace the air filter for initial improvements. With an aging vehicle, overall system degradation requires comprehensive maintenance to restore fuel efficiency.
