Nope. Neither do I believe that there's a gadget that you can plug into the lighter of your car that will increase your gas mileage. Swear to God, I saw this in my YouTube feed, yesterday. I had to send it to my (engineer) husband because I was laughing so hard. See, apparently, it makes it so the molecules in the gas in your tank don't get "disrupted"........or something. What's your favorite "snake-oil" gadget?
