"Hi TheOne

The Z5, changes the molecular structure of the air that passes through it and enables a better burn, its unlike the cyclone/tornado my friend (which dont work on all or very well, the Gadget man does not work on all fuel injected cars and looses power at the top end BTW, we tested it also)

So the Z5 is nothing to do with a vortex of the air for a vaporizer action,This you can see in the Z5 patent, a mixture of certain metal alloys we think its some kind of ionization of the air  :).

The Xtreme fuel treatment yes does pay for itself my friend  ;). you can see we describe it at the end of the video, he has around 320$ back every fill up a month. Plus it preserves your engine life so the savings must be scrutinized in another manner, this is why the worlds biggest mining company uses that additive (to prevent millions of dollars in engine down time).

I hope this answers your questions
regards
Ash"
