It this product is that good and been around that long, they have done a good job of keeping it out of the public eye. And, usually, if a product is that good there are others that pop up for sale, too. I don't see a lot of crankcase seperators on the market, do you? With oil additives, for example, you can get all the discredited choices at places like Pep Boys. Getting slamed by the FTC appears to be the best way onto the Pep Boys shelves. And since Pep Boys has service bays in the back of their stores, somehting like a crankcase seperator that's a mason jar with a few feet of hose selling for almost $200 would would be a great product to sell.
