Interesting comments about gas without treatment. I usually store my truck 4-6 months each winter, depending on the weather, and have never used a gas treatment. I fill the tank to the top before storage and if I can I'll start the truck up every two weeks and let it run for 20 minutes or so. Never a gas problem.
A friend stores her 47 for 6 months and just puts it away, same gas and battery connected. When we take it out it starts and runs just fine.
