YMMV. Adjust for the size and layout of your property. We've determined our minimum is twice that.

Also (not applicable to SHTF) we will be experiencing more and more gas shortages as time goes on. Don't run to empty - and it's bad on fuel pumps to do that anyway. Possibly consider getting bigger tanks as well, a nice hedge against the retardation we are and will be dealing with.
Filling my 36 gal tank is a challenge ... because the local stations cut-off the flow at $75 to $125. So it's prudent to NOT get below half a tank.
