So much BS on that site.

So he credits all California smog reduction and tailpipe emissions reductions since 1980 on only gasoline formulation? What about catalytic convertors, fuel injection, improved engine controls, evaporative emissions contols, etc etc?

I really like the claim that the Impala emitted zero emissions after using the product.

It would be sweet if someone would spend the time to do emissions on their car a few times and get some data for their "Double your money back guarantee".

My opinion - the product may do something, but there is no way it's going to meet the claims made there.
