The fuel tank capacity of the Excelle is 40 liters, which is the officially announced data. The Buick Excelle uses 92-octane gasoline, with a fuel consumption of 4.7 to 5.0L per 100 kilometers. A full tank of fuel can cover a distance of 800 to 851km. During daily driving, it is necessary to always pay attention to the remaining fuel level in the tank. This is usually observed through the fuel gauge inside the car. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments, and it is advisable to refuel when there are only 2 segments left to avoid running out of fuel midway. During the actual refueling process, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by the car manufacturer is measured from the bottom of the tank to the safety limit, and there is still some space from the safety limit to the tank opening. This space is reserved to allow for fuel expansion when temperatures rise, preventing overflow from the tank. If fuel is added up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity.

I remember the older Excelle models mostly had a 60-liter fuel tank design. My relative's 2007 model always stopped filling at around 58 liters when full. Don't force it to round up to a whole liter when refueling—leave some room in the space between the fuel tank neck and the filler pipe. Overfilling can easily cause spills that dirty the car's paint and potentially damage the carbon canister system. When the fuel light comes on, there's roughly 7-8 liters left, which is enough to drive about 70-80 kilometers without issue. However, doing this frequently isn't ideal for the fuel pump's cooling, so it's better to refuel sooner.

My 2013 classic Excelle has been running for almost ten years. The manual states a 60-liter capacity, but the most I've ever filled up is 56 liters. The gas station attendant said it's because 10% expansion space needs to be reserved. The hatchback HRV has a smaller tank at only 52 liters, while the wagon version increases to 62 liters. If you find the fuel gauge inaccurate during long trips, it might be due to a stuck float in the fuel tank, which would require disassembly for repair.

According to the information, the fuel tanks of the Excelle models from 2003 to 2016 generally have a capacity of 60 liters, but it's important to note that the tank shape is irregular. When the fuel pump nozzle automatically stops, the actual amount of fuel is usually less than 60 liters, with a safety margin of about 7-10%. The amount of fuel added is also affected by temperature, as fuel expands when hot and contracts when cold, allowing for slightly more fuel to be added in winter. If you suddenly notice a significant drop in fuel level, it's advisable to check for fuel line leaks or a clogged carbon canister.

While working on several Excelle fuel tanks during repairs, I confirmed the standard sedan version indeed has a 60-liter capacity, but later decontented models were reduced to 54 liters. Surprisingly, the wagon version features an oversized 62-liter tank, which is particularly reassuring for long-distance driving. If you smell gasoline after filling up, there's an 80% chance the fuel cap's sealing ring has deteriorated - a replacement cap costs just thirty yuan. For those modifying audio systems, be careful not to let wiring interfere with the fuel tank sensor.
