What is the fuel consumption of the old Regal 2.5?
2 Answers
The average fuel consumption of the old Regal 2.5 is 12.16 liters per 100 kilometers, with a range of 10.37~13.94 liters per 100 kilometers. Below is relevant information about the fuel consumption of the old Regal 2.5: 1. Specific details: The old Regal is equipped with a 2.5L 152 horsepower V6 engine, paired with a 4-speed automatic transmission version, with an average fuel consumption of 12.16 liters per 100 kilometers and a range of 10.37~13.94 liters per 100 kilometers. 2. Fuel consumption calculation method: (1) The basic calculation method is the fuel consumption per 100 kilometers, which is also the parameter provided by the manufacturer, i.e., dividing the actual fuel consumption by the actual distance traveled. (2) Formula: Fuel consumption per 100 kilometers = Fuel consumption (liters) ÷ Distance traveled (kilometers) × 100
I drove a 2003 Buick Regal 2.5L for several years and felt its fuel consumption was quite high. In city driving, it averaged about 11 to 13 liters per 100 kilometers, while on highways it was slightly better at around 9 liters. The car was too heavy, and the engine used outdated V6 technology, not as efficient as newer models. Plus, my driving habit of rapid acceleration didn't help with fuel economy, leading to significant fuel expenses. Also, as the car aged, part wear increased fuel consumption. I recommend regular oil changes and air filter checks to help reduce consumption a bit. If you're still driving it now, consider tracking the actual fuel consumption rather than just relying on theoretical values, as road conditions and driving style greatly affect the results. In summary, it's not a fuel-efficient car, but with proper maintenance, it can still be used for a while longer.
