Why does the newly added fuel deplete quickly?

[AylaDella]

Newly added fuel seems to deplete quickly because most car fuel tanks are designed to be smaller at the top and larger at the bottom. When the tank is full, this design creates the perception that the upper half of the fuel is consumed rapidly, while the lower half burns slightly slower. Here are some details about car fuel tanks: 1. Fuel Tank Design: The fuel tank is one of the most important components of a car. Its capacity determines how far a vehicle can travel on a single fill-up. To maximize capacity, fuel tanks are often designed as large as possible. To achieve this, they are typically not shaped as perfect rectangles, as such shapes are difficult to fit under the car. Irregular shapes allow for better placement. 2. Things to Note: If the owner fills the tank to the brim, the system will automatically add the extra 10% of fuel to the upper half of the tank, making the fuel seem to last longer. Conversely, if the tank isn't filled completely but still shows 100%, the fuel consumption may feel faster.
