We have no idea whether gasoline additive Eco Fuel Saver does what it’s supposed to: increasing your fuel mileage, cutting back on pollutants, and making your car 800% more awesome. Or maybe just those first two. What we do know is that people are stupid. It’s not hard to picture what must have happened to lead the management of this gas station to put up this very prominent sign.
Thanks to reader Ashi for sending in the photo. Update: which he found on Reddit.
