Lou,
Though I run 110 leaded racing gas in the 69 Cobra, I still use Sta-Bil in it and all of my other cars and lawn equipment for the long periods they will be setting over the Winter. I have used it for years with all of the gas we get here and it works great. No problems when I go to start something after several months of setting. I just pour it in the tank when I get ready to put the stuff away and then run it long enough to get the Sta-Bil in the lines and carbs and have had no problems.
