What are your strategies for conserving fuel while on patrol?

I've found it quite troublesome to conserve a comfortable amount of fuel for maneuvers and a search grid once I reach my patrol grid. The battery reserve is so small that I can't stay submerged for an entired day's worth of travel. I try to use my electric engines as much as possible in order to conserve fuel, but it almost seems pointless because I still end up using a considerable amount of fuel just trying to continue head way while I recharge.
