I was in the automotive section of Walmart tonight, and I noticed they have 2 new snake oil products on the shelves. The first one is some type of fuel additive from Bardahl (I think) that claims to increase your l/100km (liters per 100 kilometers) by 10 percent. Hm, gotta be the first additive that quoted something in metric. I looked further down the shelf, and I saw some XentX. $22 for a bottle or can or whatever. Being down on the very bottom shelf, the Walmart dudes must not think it's a very popular product, otherwise it would be on one of the top shelves.
