Don't worry about the CO2. The values in the game must be based on relative values; i.e. if you get to 100%, your dead. So you can submerge all day. They are only a problem when they get real high.

About fuel, you can pick out a good spot on the surface and hold still. (If you are skipper of an S-boat, this is almost a necessity.) Cruising back and forth at 10 knots does not improve your chances of making contact as much as you think.
