Fitch Fuel Cat. works.

[holbc]

So I did a forum search and saw where everyone said its "snake oil" but no one had actually tried it. A friend of mine had one on his cummins and claimed he was getting about 1.5 mpg better, but took it off because he was worried that it might cause lift and injector pump problems since there was no return line. So he gave it to me. My first thought was that it would just be BS, but it was free so why not? I was planning a trip to where he was at anyways, which was 310 miles away, but figured id do due diligence to see if it in fact did improve anything. And it actually did. Keep in mind I am very fuel conscious and always drive to achieve as much economy as possible. To limit variables as much as possible, I used cruise control, didnt stop along the way either trip, and set cruise to 65 the entire way. Filled up before leaving both times and filled up on arrivals (same gas stations so same distance, i suspect distance differences have to do with which lane I was in on turns). Here are the numbers.

1st trip (no fitch)- 310.5 mile on 18.05 gal. = 17.2 mpg
2nd trip (Fitch installed- 310.7 on 14.91 gal. = 20.8 mpg

Needless to say I was very surprised with the outcome. I was as much a skeptic as anyone, and originally would never have spent money on it because it sounds like something that couldnt possibly work, but it did, and surprisingly well. No one really knows what it does but I suspect the metal alloys in the canister split water molecules (a pretty simple reaction) in diesel fuel (water separators cant get it all and the longer diesel sits since its original refinement the more water it will contain). When water is split is becomes hydrogen which can be used as fuel, and oxygen which is beneficial to combustion. While the amounts produced is likely negligible the fact that the water is completely gone will allow for more efficient combustion which means better fuel economy. If this is the case I can see how it could work. The numbers dont lie and that is the first time ive ever achieved fuel economy in the 20's since I put 35" mud terrains on (I check every time I fill up) So there you have it, im sure people will chime in with negative comments but ill say it again, I didnt think it would work and the only reason I tried it was because it was free, and it actually worked quite well so dont knock it till you try it.

I want to know more about this. Lol. First of all where can you buy them and how much do they cost? What is involved on installation? Sounds like an awesome deal! BTW I noticed you are running Cooper STT's. Thumbs up. I work for Cooper Tire and Rubber Co. in Texarkana, AR. I had the STT's on my Jeep. I loved them. I sold the Jeep and bought my Super Duty. It has 35" Nitto Terra Grapplers. They were brand new when I bought the truck 4 weeks ago. I would really like to put some STT's on it but I would like to sell the Nitto's first. Lol.

WOW that is a good jump in MPG's

Color me skeptical still. I've seen quite a few reputable shows test this thing out with no improvement in mpg. Hell, a decent tailwind could net you 2-3 mpg on a 300 mi trip.

Out of curiosity, did you fill up on diesel all the way to the top of the filler neck (to the cap) when you did this test?

Where was the trip (starting point, ending point)?

[PGreenSVT]

Yeah, running into a headwind one way and a tailwind the other could make a world of difference in fuel mileage. Keep posting after several more tanks and see if you maintain an increase. I too am skeptical but will try to keep an open mind. Everything that is supposed to gain you mileage has lost me mileage on my truck lol.

I have allwase wanted to get one!!! But I did not think it was worth the $300

I filled to the click both times, however the "lie-o-meter" was showing 17.5 on the first trip and 21.1 on the second so it shouldnt be off too much. But let me use it for a while before going and buying one off what ive said. Ill keep you posted to the results. But today the lie-meter showed 22mpg to work and back which is a 60 mile commute each day. my tank is currently sitting at just under a half a tank and ive gone over 400 miles on it so far, which normally im stretched to get 410-420. It seems to be working quite well and ive noticed my rpms are staying lower at higher speeds, around 1650-1700 at 65mph and dont fluctuate much on hills. Ive seen the test reports and most the diesel tests were done on the 5.9 cummins, said they saw a 1-1.5 mpg increase, but weren't sure if that margin was enough to draw a conclusion. Those numbers are what my friend with the cummins noticed as well though. I suspect it is more effective on the 6.0 because the fuel system has a return line, so instead of fuel passing through the canister once on a cummins and going into the motor it could circulate through several times. None of these test ive found were done on the 6.0. But dont go buy one yet, like i said mine was free so i had nothing to lose. Let me use it for a while and i'll continue to post my findings accurately and let you guys decide if it is worth the money. as far as install goes it only takes as long as it takes you to take off the air intake and put it back on. It just clips into the quick connects on the right side of the motor, its a piece of cake...anyone could do it.

Ive made the trip several times to this place and never gotten the good of fuel economy ever, but i wondered if altitude changes might have been a factor but where I live is 1100 feet above sea level and where I went is 245 ft above sea level, so in a way I was going downhill the first trip...

[smokersteve]

Where did you get it?

The cheapest I have seen it is for $328.

There are allot of great testimonials on there website about the increase of fuel milage and the reduction of the carbon output, but you cant believe everything you read. I for one, am glad to here from someone who uses it on the forum.
