Thanks, that's a good suggestion, but normally fuel consumption is relate with your speed in SH3 stock.. and it's more evident in GWX2.0.
So, in this way your crew will seem eat more at flank speed instead of 2/3!! And if you decide to stay with your engines stop in a gulf for some week?
In the other post of mine, i just thought a CO2 indicator, because it's indipendent from parameters as speed, meteo conditions, and so on..
Anyway, maybe we need to wait a SH5 to see a routine sub managing...
