Don't forget putting helium in your tires to make the car lighter.There was that thing you installed in your lighter and it "cleaned the electronics." Here's just one of the teardowns of the product and you'll see what it is. I find that the best comment is, "I have one in my Tesla and I haven't visited a gas station in months! Amazing device."

If you notice, when the price of gas goes up, so do the ads and variations of these products.
Remember there were magnets that you put on your fuel line too.
