...need help here...I just saw a guy selling this product on the market and of course had to check it out,but he did not speak English and info was in Thai.

I did found identical info on the web,so I wonder,if this thing actually works,or is it just a sales gimmick?All the 'advantages' sound great and almost 'to good to be true'...don't you think?(and NO,m not advertizing here)

Seems like a pretty neat idea. You just have to wonder why manufacturers, always hungry to gain a performance/economy advantage over competitors, don't do this anyway?

Not if the oil companies had their say

But.....it does not work

If its a new device maybe, if its been out a few year then it is no good.
