The fuel tank capacity of the Cadillac CT6 with a 2.0L displacement is 72L, as officially announced. Owners of the Cadillac CT6 with a 2.0T engine can also check this information on the vehicle's configuration sheet. The Cadillac CT6 requires 95-octane fuel and is equipped with a 2.0T turbocharged engine producing 237 horsepower. Its fuel consumption is 7.1L/100km, allowing a full tank to cover approximately 1014 kilometers. During daily driving, it's essential to monitor the remaining fuel level in the tank. This is typically done via the fuel gauge inside the vehicle. Under normal circumstances, the gauge accurately reflects the fuel level. The fuel gauge usually has 5 to 6 segments, and it's advisable to refuel when only 2 segments remain to avoid running out of fuel mid-journey. During actual refueling, the amount of fuel might exceed the marked capacity. This is because the manufacturer's specified tank capacity is measured from the bottom of the tank to a safe level, with additional space from the safe level to the tank opening. This extra space accommodates fuel expansion due to temperature increases, preventing overflow. If fuel is filled up to the tank opening, the actual refueling amount may exceed the marked capacity. Other factors affecting fuel consumption include: Vehicle weight: There's a direct correlation between weight and fuel consumption; a 10% reduction in weight can lead to a proportional decrease in fuel consumption. Vehicle aerodynamics: A lower drag coefficient reduces fuel consumption, while a higher coefficient increases it. Tire pressure: Low tire pressure increases friction and adhesion, leading to higher fuel consumption. Driving habits: Aggressive acceleration and frequent braking can significantly increase fuel consumption. Wind direction: Tailwinds reduce fuel consumption, while headwinds increase engine workload and fuel consumption. Road conditions: Flat roads result in lower fuel consumption compared to rough or steep terrains. Additional electronic devices: Using accessories like air conditioning increases fuel consumption.

I've driven a CT6 for many years with a fuel tank capacity of 78 liters. In actual driving, a full tank can cover 600 to 700 kilometers, depending on road conditions and driving habits. I mostly drive on highways with a fuel consumption of about 10 liters per 100 kilometers, so a full tank easily lasts me a week, reducing the hassle of frequent refueling. I remember a few years ago when I drove a smaller car with only a 50-liter tank, I always had to look for gas stations on long trips, which was quite a hassle. The CT6's range design is very thoughtful, perfect for a seasoned business traveler like me, balancing comfort and efficiency, making long-distance travel much more worry-free.
