The world is full of scams and gimmics that claim to increase vehicle performance and mpg. Like most consumers, I was skeptical with any product that claimed mpg increase and emission reduction. When I was first introduced to EnviroTabs and considered marketing and selling the product, the only way I was comfortable representing a new product was to research the industry behind the development of the product, and to conduct field trial tests myself. In the fall of 2010, I conducted field testing on cars and truck, gas and diesel, and have found favorable results in most applications. The product has proven to work, and work well.
