I just did this two weeks ago. Filled the tank with non-ethynol premium and used Stabil. Topped off all of the fluids and aired up the tires. I also stuck a floating battery tender on it. We occasionally get decent days during the winter and I am always ready to go. Last January 6th, it reached almost 60 degrees on a Sunday so we got the cars out and ran down the highway for a beer. Got home and put her back to sleep for another 8 weeks.
