Fuel needed

[VIPer530]

Hey everyone,

I'm pretty new to this game, and on my first patrol near Japan. I refueled my boat at Midway, but still, arriving at Japan, more than 50 % of my Diesel is gone. So certainly I'm not gonna make it back.
I tried to get Diesel in some of the smaller harbours, since the handbook says you can get Diesel in neutral harbours. But when I arrive there, nothing happens. Is there any trick I should know?

The Japanese have taken Manila out, and I'm not gonna make it to Soerabaja.
Is that the end of my patrol? If so, what did I do wrong?
> 50% of the Diesel were gone when I arrived in my target area, that's a fact.
Any suggestions?

Thanks!
