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.
Our 30+ Fitch Fuel Catalyst customer reviews have an average rating of 4.50 out of 5 stars. To see specific reviews about your vehicle, please select your year, make and model from the drop down above.

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.

Have used for years. Mileage increases with use. MX5's have problem with pre-detonation. Never happens with Fitch treated fuel. I even ran 87 octane with no "Ping". With no pinging, cam and ignition timing stay advanced improving performance.

I am a long time and firm believer in Fitch. Been using the pellet type for years now. Read all the hype and one day just decided to order some and try it for myself. It works so well I have hundreds and hundreds of dollars of these things in use right now in all manner of fossil fuel burning items, although this is the first time I've ever ordered this canister type for a vehicle. I don't look at Fitch as a mileage thing. To me, it's simply a "best fuel you can possibly burn" kind of thing. I'm sure there's some extra mileage in there somewhere, but what I like is looking at the exhaust of all my stuff (lawn mowers, generator, snowmobiles, kerosene heaters, weed whackers, my truck, etc.) and seeing CLEAN mufflers and CLEAN burning kerosene heaters and CLEAN tailpipes, as well as CLEAN carbs and CLEAN fuel injectors. Was talking with a good friend of mine a few years back about Fitch. I took him into my garage and showed him the business end of my kerosene space heater (the kind that looks like a jet engine). His exact words upon seeing my totally clean kerosene heater that I use as my sole source of heat in the garage during the winter was, and I quote, "Holy sh**!" :) Needless to say the man is a Fitch man, today. :) If the fuel is burning so much cleaner with Fitch than without it you just know you're squeezing every ounce of energy from whatever it is you're burning. :)

This product is awesome. With gas prices over $4 in Virginia. I am exstatic over the ability to run regular unleaded and tune my truck to the tune of 24 mpg in a 6000lb beast!! My wife still cant believe it. Keep up the good work. All of my vehicles including my motorcycle will get one of tgese bad boys!!!

I ordered the Fitch Fuel Catalyst for my '06 Cadillac CTS-V. Having a slightly modded, 400+HP V-8 as a daily driver is fun but can be a bit taxing on the wallet. I therefore looked into using the Fitch Fuel Catalyst to help make the 78 mile daily round trip a little less costly. While I've not noticed any large improvement in overall mileage, what I have noticed is I can use regular unleaded vs. the premium I've always had to use for my 10.9:1 compression ratio without losing any mileage or power. THAT is very important to me. Plus, I don't have to worry about putting in an off brand fuel anymore. The price alone is worth that peace of mind.

I unfortunately am required to undergo the biannual CA smog check program. I use this vehicle very infrequently therefore I do not know how much it is helping. My shop which did the installation was very impressed with the quality of the components and that it has the C.A.R.B. registration.

I noticed a small change in performance and maybe 1mpg difference. It's kind of big and the only place I could find to mount it without drilling was right above the radiator. Obviously not the best place to put it since it is suppose to be in a cool spot

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.

Hi, Horsepower increases really depend on the quality of gas you're currently using. If your tank is full of lower quality fuel, the Fitch Fuel Catalyst will correct it, resulting in more power. If the fuel is high quality, there isn't much the Fitch Fuel Catalyst can do to improve it.flag Accept Answer

Is there any video that shows you how to install the catalyst? i've searched but had no luck. I'm really considering this but not knowing how to install it is keeping me from buying it. any gas mileage saved on a Tahoe is a plus in my book. Thank you.

How exactly does the catalyst work? Can't find the answer anywhere...

Hi, According to Fitch, the catalyst used breaks fuel down into smaller, easier to burn particles. This means that less fuel is required to get the same power output.flag Accept Answer

Hi, 95% of time I am sitting stuck in traffic jams in my city. In addition, fuel quality here is way below standards. Will your enhancer help improve quality of really bad fuel and will it enhance mpg while in heavy traffic? My 2006 v6 4.0L 4Runner gets about 13 mpg in summer, about 10 mpg in winter in the city. On highways, it gets around 22 mpg.

Hi, That's hard to gauge with traffic jams because engines are least efficient at idle. The term "city" mileage refers to speeds around 35 mph with a few stop lights in between, and your truck would normally get around 16-17 mpg in that situation. But with the truck stationary or moving under 10 mph, fuel mileage calculations go out the window. It might be more accurate to record engine run time like a generator. The Fitch Fuel Catalyst will ensure your engine gets the best fuel possible to build power and run more efficiently in general. I would expect slight gains in heavy traffic, but nothing substantial.flag Accept Answer

2008 Saturn Outlook
I've had a 2008 Outlook for four years - on the highway I get about 23-25 mpg - on longer trips I use premium gas and max out the mpg and range - A truck after market retailer/installer today recommended the K & N air filter to improve mpg and power - on this site I see and considering the Fitch Fuel Catalist - Does anyone have a feel for what I could performance/mpg improvements I could expect by installing this in addition to the filters and could I expect the same improvements if I use premium fuel (92/93 Octane)?
Answered by Nathan S. — May 15, 2012 3:26 PM 1985 BMW 5-Series
You will see an increase in the 1-3 MPG range depending on the quality of fuel you are getting out of the pump. Busy gas stations tend to have higher quality fuel as the have frequent deliveries and fresher fuel in their underground tanks. If your Saturn does not call for premium fuel, I would not use it. A common misconception is that premium fuel makes more power and gets better gas mileage in any car, but that isn't usually true. Higher octane fuel burns at a slower rate but can tolerate higher engine compression before detonation. In an engine that calls for 87 octane, using 91 will provide no benefits to power or economy as the engine is not mechanically able to take advantage of it. In short, using the factory recommended octane rating of fresh fuel or using the Fitch Fuel Catalyst will give your engine the best chance at complete combustion.flag Accept Answer

I have a 2007 Chevy Impala E-85 fuel system, either E-85 or ethanol my gas mileage sucks. Do you have any suggestions to improve my gas mileage? I had an Oldsmobile Intrigue and it had awesome mileage any suggestions other than getting a different car?
Answered by Nathan S. — May 03, 2012 11:00 AM
If your Impala is a flex fuel car, then you may want to use standard gasoline as it will give you an immediate increase in mileage. It takes more E-85 or ethanol to burn as efficiently as gasoline. As a bolt on improvement, I would recommend a Fitch Fuel Catalyst, cold air intake and exhaust system to improve your MPG.flag Accept Answer

Whether your veh is a truck, SUV or Excursion> If so please let me know what your results were, good or bad. Thanks. Trying to get all the MPG I can get out of my Excursion. I wouldn't trade mine for anything. Love my Excursion. Wife loves it too.
Answered by Nathan S. — May 03, 2012 11:07 AM
You will pick up a few MPG with the Fitch Fuel Catalyst. Some gas stations stock old gasoliine in their underground tanks. Gasoline loses its volatility over time requiring more to be delivered into the combustion chamber to achieve the desired result. Fresh gasoline will give you better mpg than old gasoline and the Fitch Fuel Catalyst ensures that the fuel in your tank will burn as intended.flag Accept Answer
