Out of gas!!!!!!

[Sniper31]

This used to happen to me alot in the early days when I first got SH4. What I do now is keep a better eye on my fuel level and watch my speed (as mentioned above, Standard is the best for fuel economy). Also, if on a long mission, during day light hours I will travel submerged to save fuel, then run on the surface in the dark and recharge. This of course also helps with staying undetected, but the fuel savings with this method are not huge by any means. All that surfacing and diving is a good way to work on your incoming air raid drills and emergency diving for sudden surface detections.
