How many gallons of gas does an oil tanker use?

The fuel consumption of an oil tanker can vary significantly based on its size, design, and operational conditions. On average, large oil tankers may consume between 30 to 100 metric tons of fuel per day, which translates to approximately 8,000 to 26,000 gallons of fuel, depending on the type of fuel used. However, fuel efficiency can be influenced by factors such as speed, weather, and the state of the vessel's hull.
