mmmm... I may have misread the question, I though that by "patrol" he meant from the moment he left port until he returned back home, but if by "patrol" he means staying within his assigned grid looking for prey, then my recomendation would be to stay still, all engines stopped, submerged as much as possible, wating like a spider in it's web for the pray to come within range. That way you don't use any fuel at all.
