A罐 of gasoline typically lasts between 10 to 20 miles per gallon (mpg) depending on the vehicle's fuel efficiency and driving conditions. This range is influenced by factors such as the vehicle's engine type, weight, aerodynamics, and the driver's habits. For instance, a compact car with a fuel-efficient engine might achieve 30 mpg, allowing a single tank to last up to 60 miles. Conversely, a larger, less fuel-efficient vehicle might only get 15 mpg, resulting in a tank lasting around 30 miles. The average new car in the United States achieves about 25 mpg combined city/highway, which translates to approximately 40 miles per tank. This estimate is based on data from the U.S. Environmental Protection Agency (EPA), which provides fuel economy ratings for new vehicles.
