Ethos FR......has anyone heard of this product? Is it for real or just another "snake oil"? I came across it when surf the various web sites regarding ..fuel economy. The following web site best describes the product and its benefits. I'm a firm believer that if a product or financial offering "sounds too good to be true, it most likely isn't".
Premium in my area of NC yesterday was $4.19. Today it probably jumped another nickel or dime. I never let my tank get below a 1/2 unless I'm on a trip.

ok,good rule of thumb,expanding heat pushes pistons down[runs engine] so, if they have tests to prove that by the addition of their product that burning fuel produces more btu's it may be real.
