A typical petrol tanker can carry between 30,000 to 40,000 liters of petrol, although some larger tankers can hold up to 60,000 liters or more. The exact capacity depends on the design and size of the tanker, as well as regulations regarding transportation. These tankers are specifically built to safely transport liquid fuels over long distances.

To estimate the fuel needed for an Opel Astra to travel 15,000 miles, you first need its fuel efficiency, which is typically around 30 miles per gallon (mpg). Dividing 15,000 miles by 30 mpg gives you 500 gallons. Since there are approximately 3.785 liters in a gallon, you would multiply 500 gallons by 3.785 liters, resulting in about 1,893 liters of petrol needed for that journey.
