How much fuel can actually be added to a 50L Emgrand fuel tank?

It is possible to add 53 liters or even 55 liters of gasoline to a 50-liter fuel tank. The capacity labeled in the manual is generally referred to as the "rated capacity," while the actual fuel tank capacity is slightly larger than the rated capacity. There are national regulations regarding this. According to Clause 3.1 of "Safety Performance Requirements and Test Methods for Automotive Fuel Tanks" (GB18296-2001): "The rated capacity shall be controlled at 95% of the maximum liquid capacity of the fuel tank." Below are some precautions for refueling: 1. On level ground, the fuel gauge indicates the actual fuel level only when the vehicle's power is in the IGN ON position. 2. When the vehicle is driven on winding roads or mountainous terrain, the displayed fuel level may slightly differ from the actual fuel level (either more or less). 3. If the fuel gauge pointer reaches the red zone or the low fuel warning light comes on, refuel as soon as possible. The warning light will automatically turn off after refueling or after driving for some time. 4. It is best to keep the fuel tank at least 1/4 full. Operating the vehicle with low fuel levels for extended periods can lead to premature damage to the fuel pump.
My Emgrand's fuel tank is said to have a 50-liter capacity, but in reality, it usually only fills up to 45-48 liters. This is because the tank design includes a safety space to account for fuel expansion due to temperature increases, preventing leaks. I never run the tank dry to protect the fuel pump. The fuel nozzle automatically stops when the fuel level nears the top, indicating it's full, but that's the reserved section—the actual fillable amount is slightly less, around 46 liters. I make it a habit to refuel when the gauge shows a quarter left, adding about 40 liters each time, which is just right for daily commuting. This avoids carrying extra weight and improves fuel efficiency. This practice suits most car owners—just be careful not to overfill and damage the seal or carbon canister, which can lead to maintenance hassles. After years of driving, I've tested this approach multiple times—safety first.
