Why does the range drop significantly?

[Andrea]

There are several reasons for a significant drop in range, including liquid level sensor failure, fuel tank damage, and excessive air intake in the fuel tank or fuel lines. Liquid level sensor failure: A faulty liquid level sensor can lead to incorrect fuel level display. Fuel tank damage: Damage to the fuel tank can cause deformation, affecting the normal fuel level. Excessive air intake in the fuel tank or fuel lines: Too much air intake in the fuel tank or fuel lines can result in inaccurate readings from the vehicle's computer. The range displayed by the vehicle's computer is calculated based on driving conditions, and fluctuations are inevitable. It is advisable to rely on the fuel gauge to estimate the remaining driving distance, as there have been numerous cases where over-reliance on the displayed range led to running out of fuel on the road.
