Bolt on improved MPG's

I've been curious to see some JKers actually try this thing out. JP mag claimed a noticeable gain from the FFC they installed for their fuel savings gizmo test, I believe it was the only contraption that actually showed gains they tested. Even if it works short term, I'd be more curious to see if the gains are long-term, and if there are any other side issues from it.

There has been catalysts around for years, not just this decade. They should warranty savings. Stripping that bad nasty old oxygen from the fuel was a real kicker. I wonder why they think that nitrous oxide gas is used for a performance enhancer? Hint, add oxygen?
Have you tried the magnetic trick? You know, where they strap magnets on the fuel line to help line up the molecules for increased performance and MPG.
Keep your top on, hard top preferred to increase the MPG, tires at proper inflation, don't make left turns, don't idle too long while getting gas or at a signal light, if auto put in nuetral at long lights. Draft big wheelers (trucks) and all the other usual tricks.
Otherwise, save wear and tear on the jeep and buy a moped or something for work.

Not all forms of oxygen in fuel are benefical. Much like adding oxygen to the steel in your JK's body or frame (rust), some forms are harmful.

Q. Why don't the OEMs like GM, Chrysler, Ford, Cat., Detroit, etc. implement the
Fitch Fuel Catalyst on the cars right from the assembly line?
The OEMs don't typically add parts to the assembly line unless it saves money or they are required to add because of specific regulations. OEMs must meet certain standards set forth by the EPA and other regulatory organizations. When determining MPG window sticker numbers, the EPA requires the automotive OEMs to test on a certified fuel such as Indolene. These purest certified fuels are too expensive to mass produce and are not equivalent to what consumers purchase at the pump.

I recently bought a new 08 Wrangler 4 door. Saraha New the gas milage was 15 city -17 highway. Now with 3000 miles, it gets 15 city and 18 highway. I'm trying to find something to improve milage--improving power would be an added bonus. I'm looking at CAI's, chips, etc.
I would appreciate comments actual improvements seen and which products seem to work best. I've seen CAIs on-line for between $50 and $400, but no reviews or recommendations. Thanks.

I get like 19-21 between city and highway driving. Some things I found that work.
Don't take off fast coast down hills and to red lights, throw it in neutral down long hills, acclerate slowly. Drafting big rigs on the highway.
I have a Airaid CAI and Borla exhuast I just ordered a hypertec too so I hope to see more gains before my 33s and lift go on. I also found out i get better MPG with the hardtop off. Plain n simple drive smart on road leave the pedal mashing to the dirt.

interesting enough, i used to "old lady" drive it, short shifting and keeping rpm's low at all times thinking the eninge is spinnning less therefore comsuming less gas. i was getting around 15 mpg city.
now, i shift around 2800-3000 rpms and keep 'em higher than 1800-2000 mostly except for long straits ill 5th gear it, dipping to 1500. also, any slowing situation such as approaching a red or a turn, i neutral it. im averaging 17 mpg now.
my jeep is bone stock at the moment

Well for todays update, I drove my normal route to work and back (about 100 miles), while I have not run the tank down to do the math yet, the dash at one time climbed to 29.3 MPG,s I didn't have my camera with me to take a pic but will tomorrow, but when I got to work the dash showed 25.2 MPGs. When I got home it was 24.9 MPG's. While the dash seems to show improvements the gas gauge looks the same after a day before the bolt on, there may be a slight improvement but nothing noticeable in the gauge. I will keep you all posted. I have been noticing the sluggishness at the take off and while accelerating on highway to be a little worse than before.
