The web site certainly does not scream "this is a legitimate product". (Just saying.)
The dyno tests show increases in power.
Is it fair to say that an octane additive would have resulted in the increases in engine output? Probably, if it's a modern, computer controlled engine with knock sensor(s)?
The emission tests show decreases in some emissions, but do not show CO2 (which would indicate changes in fuel consumption), so they're mostly useless.
I saw no evidence this is a fuel saving product.
My unicorn senses are tingling!
