Quick question, my cars in the garage for the winter, and people said to add fuel stabalizer as a good precaution. Its getting real cold here in Chicago, so now that I am back from school, I was going to pick some up. Now, do I have to drive the car in order for it to properly flow through the system, or can I let it sit in the garage with the car running for like 30 minutes? And also do I need a full tank? Because I am under half right now, and theres too much snow and ice in my alley, so my cars staying put, not gonna mess up the LT's.
Thanks for the help guys!

. A little extra Stabil than what is recommended won't hurt anything so go with an estimate of what you have in the tank right now. Next year when you take it out, go fill it up right away to dilute any extra you might have added.
