Supposedly it does.

And supposedly it really did help the fuel economy in the tests - but only by a small amount.

I'm going to call the professor that ran the test at the university and find out more on it.

I'm interested ... but not enough to pay such a stupid price for it .

Somehow, I feel that this is just a case of people trying to make a buck off the eco trend.
