Looks real gimmicky. And I couldn't even find anywhere on the site that actually explains how this product works. Is it an additive? Or an alternative fuel? Or an additive for alternative fuel? Plus it says that it will cost you 60 cents per gallon and save you 3 dollars per gallon, which practically speaking would only be possible if you are already using some sort of free fuel like WVO or something given this 'magical formula.' That, and the website looks like a huge sales pitch ...
