Boost power, reduce emissions and save at the pump while you're at it. The Fitch Fuel Catalyst enhances gasoline by boosting octane and bolsters diesel by improving cetane and lubricity. Designed in union with the Department of Defense, Fitch boosts all fuel types-diesel, gas, even JP fuels.
Fitch Fuel Catalyst pre-treats fuel before combustion. By running through Fitch's proprietary metal alloy, normal fuels transform into superior-quality fuels. And, quality fuel means more power, increased MPGs and lower emissions. Plus, it allows premium-fuel engines to run lower-grade gas with no performance loss.
Not to worry, the Fitch Fuel Catalyst simply bolts right in under the hood. Each system comes with vehicle-specific quick-release fittings, so it's easy to patch right in-line with your vehicle's fuel system. What's more, your Fitch Fuel Catalyst system is backed by a 250,000 mile warranty.

A great product does exactly what it promises. An almost two mile per gallon improvement and the truck runs noticeably better. Definitely NOT A SNAKE OIL! What sold me was that this unit was Police tested and used, and they were right! I am putting two more on all of my vehicles.

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.
