Vintage Snazzy (so my adult children say)
I learn something new every day. So the 182's were supposed to have 79 gallons usable total, 39 1/2 each wing. But certain serial numbers were built in a way that only gave it 78 usable, or 39 in each wing. The fuel gauge sticks sold today measure 39 usable (for each wing of course). Some POH's in the 70's then listed only 75 gallons usable total, 37 usable each wing (which of course doesn't add correctly - but I get the rounding down to be conservative).
I'm guessing most people today just use 78 total / 39 in each wing for Weight & Balance as well as flight duration and use the 39 gallon usable fuel stick gauge.
BTW - IMHO if your life depends on calculating to that last gallon, you might be doing something wrong.
