Could the Pacific Fleet fuel a voyage to the South China Sea?

Could the fleet logistically move that far from Pearl Harbor?

Yes, with difficulty: full bunkers and eleven oilers could support the crossing, followed by replenishment in the Philippines or Singapore.

Eleven fleet oilers had a combined capacity of roughly 750,000 barrels, against about 400,000 barrels of normal prewar monthly consumption. The first nine days of wartime steaming consumed roughly the oilers' full capacity, showing how rapidly combat operations could exhaust the margin. A fleet topped up from Pearl Harbor's 4.5-million-barrel stock could nevertheless begin the crossing with both ship bunkers and tankers full. Fuel in the Philippines and at Singapore would then support the force once it reached the western Pacific. The movement would strain logistics, but it was feasible for a strategic demonstration and fits the scale of operations politicians had already asked navies to perform.
