The EPA has tested nearly every one of those "save 20% on fuel" devices out there. Their report: nearly every device is a scam, and those who do work produce benefits barely even measurable.
But I read a few people who claim that the pods work. But has there been any form of formal, peer-reviewed academic study by a third party proving the validity of the claims made by the Gas Pods?
Simply put, manufacturers spend millions of dollars to squeeze 1 MPG extra out of their car. So if they could get as much as 10 MPG, as some claim, by putting pods on, why havent they done it? Some claim looks. Have you looked at the Prius? I dont think looks was a factor when Toyota made that car.
So, what's the verdict, scam like 100% of the other devices out there, or legit?
