Note that when crafting Mobius Fuel, or for a matter of fact any type of EE fuel such as Aeternalis Fuel and Alchemical Fuel, you may put the Philosophers stone anywhere in the crafting table and place the 4 amounts of fuel using in any other 4 slots in the crafting table. It's total EMC value is 2048 making it able to make gold.
Despite common opinion, Mobius Fuel is probably not named for a Latin word. Rather, it is likely named after August Ferdinand Mobius, a German mathematician known for his "Mobius strip," a topological curiosity. This mirrors the naming of the Klein Star after Felix Klein, another German mathematician known for a topological curiosity, the Klein bottle. It appears that the idea is that these materials store energy with a high density using exotic topologies.
