I don't know if this question even belongs here so move it if necessary but here goes. A friend of mine thinks he wants to get in on a business opportunity that has to do with selling a product meant to improve mileage. Its called "MPG-Cap" from a company called Fuel Freedom International Inc. I know the company is headquartered here in Florida and is currently being investigated by the Attoreny General but that, I understand, is more for the MLM (multi-level marketing) practices than the actual product. I am wanting to know if anyone has used the product and if so, did it increase gas mileage?
