Fuel economy, tank capacities and bulk liquids cross here. The gallon on this page is the US gallon, exactly 3.785411784 L. The imperial gallon still used in the UK for some purposes is 4.54609 L — about 20% larger — so a figure copied from a British source into a US context understates the volume badly.
