Me too. But I have to refill it every couple of weeks. It keeps getting ignited and sent out the tail pipes....even during the winter. Better keep those tar sands a flowin' Jim.
I won't rub in the motorcycle ride to Cloudcroft this past weekend...that would be mean. 
To the OP....keep it full....less chance for condensation to build up and do nasty things. And one less thing you have to do come the Spring Thaw. Take it off battery tender and fire it up.

Jim....that's OK, come March and April watch the weatherbug for zip 79924. When they're predicting 60 mph winds for El Paso, you can extract your revenge. 
I swear, in the spring here, anything that isn't nailed down can wind up in the next county in an hour.

Full... and there's a reason:
Any airspace remaining in the tank will allow moisture to condense on the inside as the ambient temp changes. (Condensation happens when it cools... every time it cools, not just the first.) That water then runs down the side of the tank, is heavier than gas, so it pools in the bottom ... potentially allowing rust to form on the inside of the tank.
Keep it full, there's less air space, so less condensation.
This all happens in the summer too, but if you're driving it frequently, then the water stays stirred up in the gas, and is ejected through the tailpipes

Throw the stabil in on an empty tank, then fill up. Put some miles on the car to give the stabil a chance to work its way through the engine components, then park it.
