Ethos has been all hype to date and no one has used it yet and my question is, why did Fuel Zone, which is same as Ethos fail in NA? Was it because of product, or management?

I think perhaps everyone involved should ask Bioperformance what is actually in this 'magic pill' before putting it into their gas tank.
I would absolutely demand to know; for if it is indeed naphthalene, or a deriviative of as has been suggested, you're going to be forking out a lot more money than what you are presently saving on fuel.
Ask any former street rod racer. They used to put this in their tanks (in the form of moth *****) as it has an octane boosting effect, but, in the short (not long) term, it caused engine damage as well.
An engine with a designed life expectancy of 150,000 miles might fail at 50,000 after using such a product repeatedly.
Why and how?
This happens as a result of raising the octane (as it behaves a an ultra strong octane booster) which consequently raises the temperature of the combustion process, which then strips (by cleaning effect) the cylinder walls, pistons and rings of the protective and desirable varnish (fuel deposits) you obtain in the first 10,000, or so, miles of vehicle use. This is why your vehicle manufacturer suggests no additives of any type in this early mileage period. It is desirable to have this build up occur as it is protective in nature. Obviously over time and with poor maintenance, a cleaner would benefit the engine and improve performance, but this, if it's what has been suggested, is detrimental.

I have just been contacted by a friend of mine who is visiting her parents in Houston. Her dad is really gung ho to get into this BioPerformance thing. She called me and is trying to get me hyped up. Well, my hubby and I have lost several thousand dollars over the last 10 years to MLM's, so I have to say that I am skeptical to say the least, but when I went to the BioPerformance website, my feelings were more than validated! Lowell Mims has been involved in 2 MLM's that I have lost money on! Not only did I lose money, but I have friends and relatives that lost money as well. The telecommunications company that he cites in is bio is Destiny telecom, which bilked lots and lots of people out of lots and lots of money. He got out of that one right before it tanked and claimed he knew nothing, and the other one was a diet pill similar to Metabolife that we were also involved in (can't remember the name of that one)and also lost a couple of thousand bucks on. I would highly advise staying away from anything this guy is involved in from personal experience. Yeah, some people make money from this, but most don't. I wouldn't trust his gas pills to do anymore than his diet pills and prepaid phone cards did, which is NOTHING!

After being told by friends about how great a product the MPG Cap from FFI is, I decided to do a test run.

So I went for a 440 mile drive and gauged the gas mileage. Got 33 mpg. Then added one MPG-Cap when I filled gas, ran the car for a week, and refilled (on empty tank) for a second test drive. Same route, same time of day, same weather. Did not get a chance to finish the same route before car was running out of gas ... this time I only got 28 mpg, a 15% decrease.

So if the O2-sensor is the issue here, that means that the O2-sensor / car computer should be properly calibrated by a garage using the gasoline/fuel enhancer mixture, unless you want to void the warranty on the car (My car is one year old, a Toyota Celica GT). That also means that I am stuck to using the gas pill after tuning. If not, I risk damaging the engine in the long run, unless I have the sensor/computer recalibrated, right?

I have tried these pills and not only has my gas mileage gotten worse but the company is skating around the issue of both a refund and future billing for more product that I do NOT want. Below is a copy of the email that I sent:
-------------------------------------

My name is Scott *** ID# ****. Please cancel any future autoships immediately as well as the autoship that I have yet to receive but that I was charged for on 1/19/06 and refund that payment to my credit card on file. I also need to find out about your return policy on un-opened bottles of this product.

I have kept very accurate details on my mpg for some time now. The last 3 averages BEFORE using BP were 15.1 , 14.9 and 15.2 respectively. Since using your product my mpg have actually gone DOWN to 14.1 and 13.9 under the EXACT SAME driving conditions. I am willing to keep the one open bottle that I have been using and will continue till the 4 tank recommendation you have posted but at this point and with the results I have seen after 2 tanks I definitely do not want to pay for more product nor keep what I have not opened.

I am a very reasonable person but this has been an outrage thus far. I live roughly 90 miles from Dallas and yet the order fulfillments have taken weeks (like I posted above I still have not received my second shipment and no longer want to, so please refund the 63.82 to the CC on file). Also again please provide return and refund information for the 3 bottles of pills and 1 bottle of powder yet un-opened otherwise I will be forced to post my actual results to several of my own websites, watch-dog & scam buster sites as well as the BBB to name a few.

--------------------------------------

No response to the first email, the second email I sent prompted a response:
----------------------------------
To insure it is the correct person making the request, you cannot send an email to cancel anything with BioPerformance, Inc., you must notify the company in writing.

Thank you for allowing us to be of service to you.

BioPerformance, Inc., 1300 W. Walnut Hill Lane, Suite 100, Irving, TX 75038.

I also sent an email directly to Lowell (Pres. and minister)with no reply at this point.

Beware, this is a scam!

Until now- "Ethos FR” was only available in large quantities mainly for the bigger outfits. They have now teamed up with "4-Ecorp " to distribute their product via Networking and are in the process of moving their warehouse from a 20,000 sq/ft facility to their new Building of over 70,000 sq/ft.

As with any Advertising-The Best Advertising Bar None is always through word of mouth and with a product that does everything is says it will do (and more) they are banking that the word will spread very Fast on their products as we'll as their Opportunity to help distribute their products.

So far that's exactly what has been happening. 4-Ecorp opened its doors just 10 short days ago to start pre-enrolling for their distributorship program. In this short time over 14,000 people have already signed up and they are expecting between 30-40,000 members before they Officially Launch. You can still pre-enroll for Free and reserve your spot for the Best possible position in this Exciting Company that will save us all a lot of money each time we go to fill up out tanks.

They have the Dominant Product in this Industry and the Word is spreading FAST as they continue to grow and make "Ethos FR " and "4-Ecorp " household names as the price of gasoline and diesel continue to sky rocket.
