Gasoline and diesel fuel degrade during transportation and storage. The Fitch Fuel Catalyst restores fuel to its optimal state for more efficient combustion, which results in increased fuel mileage, more power, and reduced emissions. Cleaner burning Fitch Catalyst treated fuel also keeps engine oil cleaner for extended change intervals, and reduces fuel system maintenance.

The Fitch Fuel Catalyst is the product of Advanced Power Systems International (APSI), Inc. of Torrington, CT. The company was founded in 1994 by a famous race car driver and inventor John C. Fitch, with the objective of creating a product that would both positively affect the environment and provide an economic benefit to the consumer. Originally conceived to provide gasoline stabilization, the production version of the Fitch Catalyst offered much more.

Many fuel treatments on the market promise better fuel mileage, but they must be added to every tank full of fuel, where they are consumed along with the fuel. Whatever mileage increases you may realize are more than offset by the cost of the additive, which must be continually replenished. Not so with the Fitch Catalyst. The Fitch is a true catalyst, which is a substance that induces a chemical reaction without itself undergoing any permanent change. With the Fitch Catalyst, you pay once and enjoy savings thereafter.

The Fitch Fuel Catalyst has been reviewed and tested by national automotive and recreational vehicle publications like Four Wheeler, Sport Truck, Muscle Car Review, Diesel Power, Diesel Tech, and others. Results varied, but generally all reported gains in fuel mileage, as well as improved throttle response, increased power, reduced emissions, and resistance to engine knock. The consensus opinion: unlike some devices that promise the world and deliver significantly less, the Fitch Fuel Catalyst works as claimed.

Fitch Fuel Catalyst Reviews

I wasn't sure what to expect when I bought this for my 2001 Buick LeSabre! I saw all the benefits from this product on CARiD so I thought well it's possible. I bought it and installed it. I did not notice any gains at all for months. Months went by and still nothing. About the 8th month after the install I started noticing a lot of white smoke coming from my tail pipe. I thought that was odd because it wasn't cold out and my car doesn't poor white smoke out of the tailpipe when it's warm out. The smoke would be more noticeable at first start up usually in the mornings. Then I started having problems with my transmission. It seems like the transmission was going bad because it was whinning shifting hard and that was odd because if a transmission was going bad you'll slowly notice it over time and not it one day like I did. A week went by and the transmission finally settled in to it's new realm. There were new dimensions to the engine that the computer had to pick up on as the catalyst was starting to work. I thought it's about time. The product says give your car ten operating hours before noticing anything. I went months and didn't see a thing but the whole time behind the scenes the fitch fuel catalyst was working behind the scenes. Amazing. My car sounds great. My engine hums like it's new. Every now and then I'll see the white smoke.
