Each year an ice-strengthened tanker delivers approximately 19,000,000 liters (5,000,000 gallons) of fuel to McMurdo Station. It is operated under contract to the Military Sealift Command.
Three types of fuel are used:
- AN8, a special fuel blend used in the Arctic and Antarctic, has a low flash point which lowers the point at which wax crystals form when exposed to exteme cold.
- Mogas, an unleaded motor fuel with additives, is used by the military.
- JP5, another special fuel blend, is used in the U.S. Coast Guard icebreaker.
