Does anyone here use drying additives? How often and how much do you use?

A) the whole notion of condensation in a partially full tank creating
enough water to impede operations is, in my view, a bit of a red herring (no
pun intended). Maybe from Labor day through September, when the days can be
warm and humid and the nights brisk and raw along the New England coast.
More likely, I think, to suffer water intrusion from other sources.

B) tossing a bit of drygas into the mix is not a bad idea, anyway. Those
smallish bottles available for automotive use are generally sized for
vehicle tanks of about 17-25 gallons, but that calculation also includes a
bit of over usage to keep sales up. I used to buy it by the case at
Autozone, and add a bottle whenever I put in 30-50 gallons.
