What is the fuel tank capacity of the Cadillac XTS?
2 Answers
The fuel tank capacity of the XTS is 70 liters, as officially announced. The XTS requires 95-octane gasoline, with a fuel consumption of 7.9L per 100 kilometers. A full tank can provide a driving range of approximately 886km. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. Under normal circumstances, the fuel gauge accurately reflects the remaining fuel. Most fuel gauges have 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel mid-journey. In practice, the actual amount of fuel filled may exceed the nominal capacity. This is because the manufacturer's specified tank capacity is measured from the bottom of the tank to the safe fill level, leaving some space between the safe fill level and the tank opening. This space accommodates fuel expansion due to temperature increases, preventing overflow. If fuel is filled up to the tank opening, the actual amount may exceed the nominal capacity.
I've been driving a Cadillac XTS for three years, and I'm very familiar with the 82-liter fuel tank capacity. When I was choosing the car, I specifically compared it with others—the Audi A6 in the same class only has a 73-liter tank, so this capacity gives a clear advantage on long trips. Last year, during a road trip from Beijing to Qingdao, I drove the entire 830 kilometers on a single tank without refueling, which was quite convenient as I watched others queue up at gas stations. However, for daily city commuting, this capacity feels a bit excessive; I only need to refuel twice a month. By the way, be careful not to overfill the tank—stop when the pump clicks off, otherwise, gasoline fumes can seep into the cabin. The fuel tank is located on the left rear side of the car, so make sure you park on the correct side when refueling.
