You can also run multiple subs at a time in 2-3 and still gain fuel. More subs will take down more enemies in the initial torpedo phase, and spread the damage taken out more, increasing your win rate and decreasing the odds of retreating early.

If you're using subs with standard resupply costs (non-remodeled Goya/Iku/Hachi, any Imuya), resupply for 2 subs will be 8/16 (2 battles) or 12/24 (3 battles). Hitting 1-2 fuel nodes there will gain 15-90 fuel per run, so you're guaranteed to gain fuel unless you're forced to retreat early.

Running 3 subs with standard resupply costs will have a per-run cost of 12/24 (2 battles) or 18/36 (3 battles). Each run will gain fuel unless you get sent on the 3 battle path and only get the minimum +15 fuel from the fuel node along the way. So on average, you'll easily gain fuel.

Even running a fully remodeled team of Shioi, Imuya, Iku, and Goya (to farm the boss), resupply for running 2-3 is 22/40 (2 battles), 22/51 (night battle at boss), or 33/60 (3 battles). So you'll still gain fuel on average.
