Fitch catalyst, is this too good to be true?

Using 93 octane & the catalyst, the fuel consumption was about 19.5 gal/hr...
Using 89 octane & the catalyst, the fuel consumption was about 20.6 gal/hr...
The big difference cam between the 89 octane (~23 gal/hr) vs. 89 w/ fitch (20.6 gal/hr)
That kit is probably a couple hundred bucks, and you're only paying $.10/gallon less for 89 octane...but using more fuel than 93 octane. Plus you get detergents in the 93 octane that aren't in the lower grade fuels.
if you need to replace it every 500miles...and it costs more than a couple bucks...there goes your $.10/gal savings.
Appears very convincing, tested by various magazines, etc, even Mallet cars, a very respected corvette tuner
Test Vehicle: 1998 - C5 Corvette
Odometer: 40,146
Test Facility: Mallett Cars Ltd. - Berea, OH
Test Fuel: 89 Octane
Baseline: Max Horsepower – 270.27
Retrofit w/Fitch: Max Horsepower - 289.43
Baseline: Max Torque – 179.76
Retrofit w/Fitch: Max Toque – 190.78
19.16 Horsepower Improvement with Fitch installed

Something isn't right with those numbers. How are they making 270-289 hp but only 179-190 ft/lb torque? Those are 4-cylinder type numbers.
I worked in the oil industry as a chemist and I find this very hard to beleive. If there was a magical additive to gain gas mileage, the big oil companies would be all over this because of the marketing advantage it would give them.
I call snake oil on this one.
Now some of the tests where they replace conventional oils with synthetics and get 5-10hp is beleivable because they are changing the motor oil, the trans fluid, the diff fluid all at one time. The reduction in friction would cause that gain.

I'm sorry.... I've got to throw this one out....
