What is the reason for the constant fuel consumption of the Volkswagen Lavida?

Reasons for constant fuel consumption: Issue with the fuel level sensor: The fuel level sensor, also known as the fuel float, may be malfunctioning. Check if the plug on the fuel level sensor in the fuel tank is loose, and observe if there is any obstruction during the sliding process of the fuel level sensor. Problem with the fuel gauge circuit: Remove the instrument panel and use a multimeter and a needle to accurately locate and inspect the corresponding fuel gauge circuit on the instrument panel. Precautions: The fuel gauge displays the amount of gasoline in the car. It is particularly important to note that when the fuel gauge pointer drops below the red line and starts to alarm, although the car can still continue to drive for 30 to 40 kilometers, it is not recommended to wait until the fuel level alarm goes off before refueling.
I've noticed that the fuel consumption of my Volkswagen Lavida has remained consistent, likely due to my regular driving habits. I take the same route to and from work every day, maintaining a speed of around 60-70 km/h, with minimal sudden acceleration or braking, so the fuel consumption stays stable at approximately 6.5 to 7 liters per 100 kilometers. Additionally, I always keep the tire pressure at a moderate level, around 2.3 bar, which helps reduce rolling resistance. If the weather doesn't change much or I use the air conditioning sparingly, it has even less impact. Regular oil and filter changes also prevent engine wear. Therefore, as long as the road conditions don't change significantly, the fuel consumption naturally remains steady. This is a good thing, indicating that the car and my usage are well-matched.
As a car owner who often does minor repairs myself, I believe the reason for the stable fuel consumption of the Lavida is due to proper vehicle maintenance. I check the engine oil and coolant levels monthly to ensure they are adequate; I clean the throttle body and fuel injectors every six months to prevent carbon buildup from affecting combustion efficiency. Changing the air filter frequently ensures smooth air intake. The tires wear evenly, and I maintain the tire pressure at the recommended value, which reduces additional resistance. Additionally, I usually drive on stable road conditions with more highway driving, and the system adjustments are precise, with no sensor errors, so the fuel consumption readings always remain consistent. If there were oil leaks or aging components, fluctuations would have appeared long ago, but after several years of driving, it remains steady.
