Fitch Fuel Catalyst Review

Gas Fuel Catalysts Parts

Save money and gas with the Fitch Fuel Catalyst: one of the most cost-effective fuel-enhancing vehicle modifications available!

The Fitch Fuel Catalyst is a safe and innovative solution that can quell the rising surge of gas prices and improve your gas mileage instantly. Once installed, you will see a boost in vehicle efficiency and noticeable improvements in fuel economy right away.

Technical Overview:

The Fitch Fuel Catalyst is a permanent fuel treatment system that installs quickly into your vehicle to resuscitate and reformulate fuel, ensuring your vehicle is operating with cleaner and more efficient gas.

As a result, you save immediately at the pump by using lower grade fuel that will perform at premium octane standards. Vehicles that normally use premium (91) octane fuel can use standard grade (87) and get premium performance. Vehicles that normally use (87) grade fuel will see increased performance from cleaner-burning gas.

Additionally, the Fitch Fuel Catalyst provides a variety of engine benefits, such as elimination or reduction of engine knock and ping, cleaner injectors and carburetors, and even easier starting. Fitch Tuning Tips (PDF)
