There was more fuel on-board for the auxiliary propulsion systems and for the various modules, but the above was the fuel used to get the payload into space and to the moon. That's a total of 3,787,350 liters of fuel, or just over 1 million gallons of liquid fuel with a fuse! Wow! Of interest: Europe is preparing plans to join the U.S. in building a manned spaceship that will take men and women to the moon.
As a result, it has been estimated that there are around 1,100,000 metric tonnes of helium-3 on the surface of the Moon down to a depth of a few metres. This helium-3 could potentially be extracted by heating the lunar dust to around 600 degrees C, before bringing it back to the Earth to fuel a new generation of nuclear fusion power plants.
