2011 Excelle's actual fuel tank capacity when full is 40 liters. Below are precautions for refueling and solutions for fuel overflow: Precautions for vehicle refueling: Use automotive gasoline only. Inappropriate fuel entering the fuel system may damage the fuel system and engine. Do not use gasoline containing methanol or alcohol. Avoid spilling fuel on painted surfaces to prevent paint damage. If the fuel door is frozen and cannot be opened, gently push or tap the fuel door to remove ice and open it. Prevent excessive fuel pressure that may cause spraying. Solutions for fuel overflow: For gasoline spills, use a broom to disperse the fuel and isolate the area, keeping people and vehicles away until it evaporates. For diesel spills, use fire sand to cover the area, sweep back and forth to absorb the oil, then place the oil-sand mixture on a sun-exposed concrete surface to dry.

As someone who has been driving for over a decade, I find it perfectly normal that the official 60L fuel tank capacity of the 2011 Buick Excelle actually holds only about 58-59L when completely filled. This is because fuel tanks have safety space to allow for thermal expansion. Through multiple tests, I've observed that when filling until the pump automatically stops, it's typically 1-2L short, which doesn't affect driving. With its fuel consumption, it can run about 400km in city driving. Don't worry about this minor discrepancy - the key is not to overfill during refueling to avoid fuel spillage or system damage.

As a young car owner who just bought a used Excelle, I was also curious at first. I checked the information and found that the nominal fuel tank capacity is 60 liters. However, after testing at several gas stations, the actual full tank usually holds around 58 liters. Engineers design with some margin to account for temperature changes that might cause leakage, so the actual capacity is slightly less. The car drives fine, and a full tank can last for a long-distance trip. However, it's recommended to occasionally check the oil dipstick and fuel quality for maintenance.

From a technical perspective, the 2011 Excelle's fuel tank is labeled as 60 liters based on an empty state. The actual fill volume is affected by temperature and pressure, typically ranging from 57 to 59 liters. The vehicle design includes buffer space to ensure safety and prevent expansion or vapor lock issues. In daily use, maintaining fuel levels above half can extend service life.
