2021 Excelle offers 4 models, all with a fuel tank capacity of 44 liters. The 2021 Buick Excelle is equipped with either a 1.3L turbocharged engine or a 1.5L naturally aspirated engine, paired with an automatic transmission (AT). All models feature front-wheel drive. In the same vehicle class, the 2022 Nissan Sylphy Classic 1.6XE manual comfort version has a fuel tank capacity of 50 liters, while the 2021 Ford Focus Sedan 1.5L manual variant has a 53-liter fuel tank. During actual refueling, the amount of fuel may exceed the nominal capacity. This is because the fuel tank capacity specified by automakers is measured from the bottom of the tank to the safety level, with additional space reserved between the safety level and the tank opening. This extra space accommodates fuel expansion due to temperature increases, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual amount may exceed the nominal capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the instrument panel, marked with E and F. When the needle approaches E, it indicates low fuel, while nearing F signifies sufficient fuel.

My Excelle has been driven for over three years, with a standard fuel tank capacity of 50 liters. I always fill it up until the pump automatically stops, which usually takes between 45 to 48 liters, leaving some space to prevent fuel expansion and leakage. With my driving habits, a full tank can cover 450 to 500 kilometers in urban conditions and up to 550 kilometers on highways. I prefer refueling in the morning when the fuel temperature is lower and the density is higher, allowing for a slightly larger fill. Regular maintenance includes checking the fuel cap's seal; a gasoline smell might indicate a leak. The fuel gauge in this car is accurate, so just refer to the dashboard display. For new drivers, filling up before a long trip is much more reassuring, but avoid overloading the tank as it can increase fuel consumption. It's advisable to choose reputable gas stations for better fuel quality, which helps prolong the engine's lifespan.

I find the fuel tank size of my Excelle quite suitable, with a capacity of around 48 liters. A full tank can handle my weekly commute. My daily round trip is 30 kilometers, and I make sure to refuel when there's about 20% left to avoid fuel pump damage from running dry. It's important not to overfill beyond the safety line, as the design includes a buffer space. During hot summers, I prefer to refuel in shaded areas to minimize evaporation loss. In terms of range, with air conditioning on in the city, it drops to 400 kilometers, but without AC, it can reach 520 kilometers. To save on fuel, I often use Sinopec's 92-octane gasoline, which makes the car run smoothly. During maintenance, the mechanic always says the fuel tank is in good condition, just requiring regular cleaning of the filter screen, which is simple and easy to do.

The Excelle's fuel tank can hold 50 liters of gasoline. As an experienced mechanic who's seen many cases, I recommend not filling it completely—stop when the pump clicks, around 45 liters is safer. The tank is designed with anti-overflow protection; overfilling may cause leaks and environmental contamination. Refuel when the gauge indicates, don't wait until the warning light comes on, to protect the fuel pump. It's advisable to check the fuel tank line seals every 5,000 km—just replace the sealing ring if there's a leak. Simple and practical advice.

Driving the Excelle Tour is truly worry-free. With a 50-liter fuel tank filled up, it can run 600 kilometers on the highway without stopping. I often go on trips with my family, and stopping at service areas to refill half a tank reduces the car's weight, saving even more fuel. My refueling strategy is to fill up to the automatic shut-off at around 45 liters to avoid overflow when fully loaded. The range depends on driving style—I can reach 650 kilometers with smooth driving. Regular maintenance includes checking the fuel tank pressure to ensure no leaks. Checking tire pressure before long trips also improves efficiency.

As a newbie who just bought an Excelle, I was surprised by its 48-liter fuel tank capacity, but the manual warned not to exceed the safe fill line. Now I only fill up until the pump automatically stops, which is about 45 liters in actual usage. For city driving, it gives me a range of over 400 kilometers. I make it a habit to refuel when the gauge shows a quarter left to protect the fuel pump. I've also learned to check the sealing of the fuel cap for leaks, and is straightforward.
