Fitch Fuel Catalyst Fuel Catalyst F5-T Review
I'll start off by saying I'm not a chemist, a materials experts or engine specialist. I'm simply an average consumer, who happens to be a powersports technician, so have some prior experience with snake oil claims re: performance enhancers in powersport vehicles.I was skeptical at first about the Fitch Fuel Catalyst, as there've been innumerable claims for mpg boosts with all manner of wacked-out, non-empirical miracle products that prove to do nothing. However, decided to give John Cooper Fitch's fuel treatment a try, as I'm a fan of his other safety creations from track and racing experience.
Received the F5T kit and decided to acid test the FFC, by using one cage of catalysts in my '00 Suzuki SV650 tank, and the other in my mother's '99 Ford Escort tank, to see if one in either had any effect at all (recommended usage is both in the motorcycle tank, and a dedicated inline unit for the Escort). Both vehicles endure ambient temps into the 90s daily, so a lot of evaporation of light chain fuel molecules in any air that gets drawn atop the fuel. Both vehicles run a mixture of 3/4 89 oct fuel and 1/4 premium fuel (prevents ping in the heat w/o costing too much). Both vehicles have regular, conventional maintenance and no other performance enhancers other than what they currently have (bike is jetted and piped, Escort's 2.0L CVH Inline-Four is utterly stock except for Bosch plugs).
Not sure how scientific that was, but the only change to the normal course of running each vehicle, was the addition of the FFC, with less catalyst than recommended.
In both vehicles, skeptical hat on, I drove with a fresh tank of fuel, and recorded if they ran differently, if at all, through the next fillup. Used the same station at the same pump for both, as always.
Bike: My SV got a very-good 190+ miles on 3.5 gals of fuel before the FFC, so it wasn't hurting in economy. But I did notice the bike idling a lot more consistently whether hot or cold, and a newfound ability to pull off-idle without the expected small stumble that cleared its throat I was so used to. That was unexpected and very welcome. The first tank with the FFC got a small improvement -- about 1% or a little less than 3 miles gain from the same 3.5 gals. This isn't a gain that can be directly credited to the FFC, as it's too small over nearly 200 miles to not blame on ambient temp/humid, or a few hard rollons. But the bike is tangibly easier to ride now, and seems a bit less strained at certain rpm.
Since the two F5T cages should treat up to 10 gals, one should treat 5, logically, and my tank is 4.2 gals total. So perhaps it didn't need two to do its work, but I'm now curious if another will change behavior even more for the better. BTW, no problems so far with it and the fuel filter in the vacuum petcock.
Car: The Escort, first of all, has a turn in the filler pipe where the neck meets the tank, that doesn't let the F5T cage fall in -- so it obstructs the neck and hinders filling a small amount. Teaches me to ignore manu. recommendations! But it does dip into the fuel apparently, as I have noticed changes...
First, similar effect as in the bike -- idles steadier, quieter. Noticed a small gain in mpg, but more significant than the bike's... in full economy mode (no A/C, 55 mph in the right lane, tires filled properly, no extra weight), it struggled to maintain 21 mpg with its ancient SOHC 2V CVH Four. If the A/C was used when appropriate, it dipped into the high teens, dismal. After the FFC was dropped in however I've noticed a solid gain in mpg: with A/C in use, I got 21 mpg. In eco, it went to 23 mpg, a gain of 8%. This is with a motor (albeit lightly used and properly-maintained) that has almost 90K on it. It's never going to be a Prius... but I'll take 2 mpg for a one-time $50 investment, any day of the week.
Another cage in the tank filler is out of the question with the obstruction issue... but am now genuinely considering the inline kit. Something is happening, and no amount of wishful thinking is going to gain 2 mpg with the traffic around here. I've not changed the still-OEM O2 sensor yet, which may net even more gains. BTW... on the fourth tank since the FFC was inserted, and the gain has remained.
Conclusion: for a motorcycle, the F5T kit is worth it, even if the mpg gains are minimal -- you'll notice how much you're compensating for inconsistent throttle response, when you no longer have to. Not sure for a sportbike (5 gals capacity or less) that both cages are necessary, as there was plenty of change with just one unit. For the car... even with much less catalyst than recommended, and not in the ideal placement, I gained a solid 2 mpg. Satisfied. :)
