Why is the fuel consumption of Lavida over 10L/100km?

Here are the reasons for the high fuel consumption of Lavida: 1. Improper driving habits: Fuel consumption is closely related to the driver's habits, specifically manifested in not turning off the engine during prolonged idling or frequent ignition, aggressive acceleration or frequent braking, driving at high speeds in low gears or low speeds in high gears, etc. These driving habits significantly contribute to increased fuel consumption. 2. Abnormal tire pressure and tire wear: Low tire pressure increases friction between the tires and the ground, leading to greater resistance and higher fuel consumption. Normal tire pressure is around 2.5bar, which can be slightly reduced by 0.1bar in summer. Of course, tire pressure should not be too high either; it's best to inflate according to the vehicle's standard values. Additionally, if the tires are severely worn, frequent slipping can occur, which also increases fuel consumption. 3. Fuel quality and carbon deposits: Many car owners overlook fuel quality. Poor-quality gasoline can lead to increased carbon deposits, which roughen the intake pipe walls, affecting the intake efficiency and the quality of the air-fuel mixture, causing a sharp rise in fuel consumption. Therefore, gasoline quality should not be ignored. Regular maintenance at a 4S shop is a forward-looking investment, not only ensuring the vehicle's normal performance but also inadvertently saving the owner from unnecessary future expenses.

The Lavida's fuel consumption being relatively high, exceeding 10 liters, is quite common. I've been driving this car for several years and have encountered similar issues myself. Generally speaking, driving habits are one of the main reasons. For example, frequent sudden acceleration or hard braking can significantly increase fuel consumption, especially in congested urban areas where the engine often operates in inefficient ranges. Checking tire pressure is also crucial, as insufficient pressure increases rolling resistance. If the air filter is dirty, the engine won't get enough air, reducing efficiency and leading to higher fuel consumption. Additionally, check for unusual loads or excessive use of the air conditioning, as the AC puts a significant burden on the car in summer, affecting fuel efficiency noticeably. I recommend first inspecting the tires and air filter yourself and performing minor maintenance. If the issue persists, take it to a shop to check for faulty spark plugs or oxygen sensors. Developing good driving habits, such as smooth acceleration and deceleration, can save a lot of fuel. With proper daily maintenance, fuel consumption will naturally decrease.

My Lavida sometimes consumes over 10 liters per 100km, which is really frustrating. I believe starting with routine maintenance can help. First, check the engine oil condition - old oil increases engine friction resistance, and regular replacement can improve efficiency. Remember to frequently check tire pressure, maintaining around 2.4 bar is generally optimal. Try to avoid rush hour traffic when driving, as stop-and-go conditions are most fuel-intensive. I've also found that vehicle weight matters significantly - don't overload the trunk with unnecessary items as extra weight naturally increases fuel consumption. Clean the air filter regularly to prevent clogging that affects air intake. If these simple measures don't work, there might be deeper issues like injector carbon buildup or ECU control abnormalities, requiring professional diagnosis with specialized equipment. Keeping the vehicle light and developing low-RPM driving habits can significantly improve fuel efficiency over time. Don't overlook small details - their cumulative effect is substantial.
