Okay so I take my Balao out of Midway to the north tip of Japan by the Kurils.
I head there at ahead slow and my fuel usage is 1/4 a tank by my arrival.
I patrol and rack up a killing in the north. With 35% fuel remaining and me being closer to Midway since I headed south around Tokyo I should have fuel to spare right? WRONG!
Again at ahead slow I watch my fuel gauge just sink until 700 miles from home fuel is used up. No damage and no heavy weather It seems to me that much like a car the last half a tank goes much faster than the first half!
