tankful

Tankful is a term that refers to the state of a vehicle's fuel tank being full. It commonly appears on the dashboard of a car, typically indicated by a fuel gauge or a digital display. When the fuel gauge needle points to the "F" or the digital display shows 100%, the tank is considered tankful. This signifies that the vehicle has reached its maximum fuel capacity.

The term "tankful" is often used when discussing the cost of refueling a vehicle. For example, someone might say, "It cost me $50 for a tankful of gas" or "I need to get a tankful before our long road trip." It implies that the entire capacity of the fuel tank has been replenished.

While primarily associated with gasoline or diesel vehicles, the concept of a tankful can also apply to other vehicles that use liquid fuel, such as motorcycles or certain types of boats. Electric vehicles do not have fuel tanks and therefore do not experience a "tankful" state in the traditional sense, but rather a full charge. The opposite of tankful is an empty or near-empty fuel tank.
