If you live in an area wich constantly swinging temperatures between freezin and not freezing, contensation can form in your tank and you will litterly collect water in your tank. If you fill up, the volume of air to collect the moisture is much less and less condensation can form.
What you state was true years ago when fuel systems were open to the atmosphere, but with today's strict EPA regulation no fuel system is open to the atmosphere. No atmosphere, no condensation.

I have seen that "no fuel system is open to the atmosphere" statement several times, and it got me wondering; If the fuel tank is completely closed, no vent to the ambient air, how does the fuel get drawn from the tank without causing a vacuum in the tank? There simply MUST be some kind of atmospheric vent to prevent that scenario. It might be through a carbon canister to prevent gasoline vapors from escaping, but there simply HAS to be a vent of some kind! If ANY humid air gets in the tank, there CAN be condensation when the temperature drops.
Activated charcoal is not a dessicant, it will not absorb much moisture.
Both. I'm in Georgia and I don't normally winterize but if I'm not going to use it for the next 45 days or so, go to the service station, add the Stabil then fill up the tank. When I leave, I crank up the generator. The drive home assures me that the Stabil has mixed with the fuel and has made it all the way through the system.
Incidentally, it's a Fleetwood, 80 gallon tank.

starting with OBD 2 they use diferent canisters, the biggest diference is the size along with diferent media types. As far as pulling a vacuum, its true. Chrystler checks the system for leaks by measuring the vacuum over time,,, ford and GM mostly use pumps to pressurize. EVERYTHING atmosphere wise is vented through the system including the fumes on fillup ask me how I know, I worked on quite a few and personally designed the Delta system (at Solvay, now Inergy)http://www.inergyautomotive.com/httpdocs/public/index.php
I am a big believer in Stabil. I use it in all my lawn equipment and in my 88 Driftwood that by the way has that 120 gal tank. Yes I am happy to see gas prices down.
I use Stabil in the spare gas for the mowers and weed eaters year round. The gas now days doesn’t last more than 30 days before it starts to degrade and Stabil improves performance.
