Purchased because a good friend of mine swears by these. He runs his 2014 HO Jeep on a 93 octane tune with regular, also swears it improved his mileage. I'm not one for snake oil but it does work. I can run mid-grade fuel with a 93 oct tune, previously even 93 fuel would periodically ping. I have also noticed 1.5 - 2.0 MPG better fuel economy. I am very pleased not to have to buy premium for daily driving.

I love my Nissan Titan but the only complaint I have about the truck is that the fuel milage is pretty bad compared to previous trucks I've owned. So I bought a Fitch Fuel Catalyst and a Superchips Codex to experiment with. Long story short, I was able to gain 2 real mpg's average after a lot of controlled testing using this combo. More testing to come.

Been using these for years; and have had good results with every auto application. What changes is the ability to use regular gas in a high compression motor (11:1)with no measurable timeing roll back and no detonation. Regular gas has a bit more energy, and this is reflected in better gas mileage. Suggest anyone considering this product first research John Fitch on Wikipedia, and then go to the Fitch site.

I been looking for ways to save on fuel. This beast love to eat so had I had to put him on a diet. The Fitch Fuel Catalyst worked, I gave it a week to see how much fuel I was saving and I am averaging between 2 to 3 mpg. I installed it in the engine compartment driver's side radiator cover. You will need a special tool to remove the fuel clip and once your remove that, I just had to remove one screw on the top right side of the radiator and replaced it with a longer screw. Total install took about 25 min.

Looks like the fitch system works to me. I have noticed a gain around 1-1.5 mpg increase. Couldn't tell you how easy it is to install since I had my Nissan dealer do it for me. I didn't feel like messing with the fuel lines on my truck. Get one, I'm pretty sure you'll notice an improvemnt in mpgs.
