Fitch Catalyst

Reviewed By Scott J (SUWANEE, GA) Reviewed for a 2010 Ford Mustang —4/17/2015 1:24 PM

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.
