As Sheriff of Duval County in San Diego, Texas I strive to improve on our equipment
for my Deputies and Cut costs to our Taxpayers. When I was informed about the
ECO-Systems I was excited to see if this product really worked. My officers often
complain about the performance of our patrol cars and I wanted to see if this product
would take care of the hesitation and the clattering of the engines and secondly, I am
often reminded of fuel costs by other officials. After installing the ECO-Systems on
our entire fleet I am glad to say this is one product that does what they say it will do.
My officers are happy with the performance of our fleet. The hesitation and clattering
is gone and the performance is where it should be. Our units are getting 10 to 12
percent better mileage. My Sheriff’s pick-up with a 5.4 liter V-8 is now getting about
18 miles per gallon where it used to be at 15.5.
This fuel savings sure helps my budget. I encourage all law enforcement agencies to
look into this product for your fleets.

I have installed the ECO-Systems on Ford Crown Victorias, Dodge Charger Hemis
and Chevrolet pickups. We have increased the mileage by 2 –3 miles per gallon. The
most notable change was the performance. The hesitation was eliminated and the
acceleration performance increased. I installed one on my Crown Victoria. I noticed
the difference immediately when I accelerated. The maintance division has checked
the spark plugs. The plugs are carbon free. When we retire a high mileage unit, we
remove the ECO-System and install it on the new unit. We will continue to install the
ECO-Systems on our fleet.

On 17 August 2007, B6 Enterprises agreed to have installed an ECO-Systems Fuel
Vapor Enhancer on B6 Enterprises' truck 024. Our intention was to validate ECO-
Systems' claim of a 10% fuel savings. At the time of installation, truck number 024
was consistently delivering 6.47 miles per gallon.
Over the course of our test, lasting 30 days, we saw an improvement of 11.6%,
increasing our mileage to 7.22 miles per gallon. Based on this successful test we
have installed ECO-Systems on the entirety of our fleet.
At this rate of return it will take less than one month to recoup the cost of the ECO-
Systems. As a matter of fact by the time our test had ended we had already saved
enough fuel to pay for the ECO-System we tested on 024.
Every day we waited to finish the testing cost B6 Enterprises money in saved fuel
costs. In such an incredibly competitive industry where savings are so hard to come
by we would have done better to install the ECO-Systems fleet wide at the beginning
of the test and simply relied on ECO-Systems' money back guarantee to protect our
My hesitation was based on the countless products that make the same claims ECO-
Systems did. I have since recommended the technology to my friends, other trucking
company owners, and I have allowed ECO-Systems to use my name and
endorsement in their marketing efforts.
I purchased my 1st ECO System about four years ago after seeing a news cast
on WOAI. After installing the ECO System on my Van the fuel economy increased from
an average of 25 mpg on the highway to 28 mpg. The city mileage increased from 18
to 20 mpg. This is my new Magnum and it's also equipped with the ECO System. My
Son who lives in Fredericksburg VA, also has his vehicles equipped with the ECO
System. I inform as many people as I can about the ECO System.
To the ECO Guys, My name is Joe Martinez and I first came in contact with your
product in 1999 with the San Antonio Fire Department where I work at. At that time
we were testing your product on our fire trucks and EMS units to reduce emissions. I
finally purchased a unit in 2000 for my Toyota Pick-up and it is still running GREAT
today. I used to have problems with the carburetor and rough idling and my mileage
was decreasing. After installation of the ECO #1 on this 4 cylinder I have not had any
problems with my carburetor, the rough idling is gone and my mileage is back up
again. In fact she’s never run this good! I have seen many of our trucks that smoked
pretty bad clean up with your systems. It also helps the environment for cleaner air.
I recommend this product to everyone.
I bought my new EcoSystem about 3 months ago for my Chevy Suburban, and I’ve
been thrilled with my gas mileage. I’ve improved by 2 miles per gallon. The Eco
System will pay for itself in less than a year! The Eco System was an easy choice
for me. The system is simple and proven, and the installation was quick. I’d recommend
the Eco System to anyone with a large SUV. It saves money!

"We were skeptical at first! We installed the Eco System on a variety of vehicles and
in every instance not only did it save fuel and increase performance, it also
significantly reduced smoke!"

My name is Tony Campos and I am the shop Supervisor for C-6 Disposal here
in San Antonio. I was having problems with some of my Mack engines due to excessive
smoke. The nature of our business is a lot of stop-n-go driving and a lot of idling as
well. A sales Rep came by and told me about the ECO-Systems and the success it
was having on other fleets. I decided to try it on 2 of the trucks that smoked the
worst. I have to admit at first I was skeptical, but seeing is believing. I was surprised
at how quickly it worked at reducing nearly all of the smoke. I then had it installed on
the rest of the fleet and it performed better than I had expected. I have used the
ECO-System for nearly 2 years now and recommend it to all fleets. I even use it on
the Ranger Pick-up for our Sales rep and on My F350 Powerstroke. If you drive a
Powerstroke 7.3 or 6.0 you need an ECO-System, it will improve your performance
and fuel economy. It also makes me feel good about doing our part to help clean the
air we breathe.
We currently have close to 130 Eco Systems installed in our fleet, which consist of
100 Minivans and 30 Motor-Coaches. In studying our before and after effects we
have averaged about 10-14% in fuel savings. We’ve also had less maintenance
needed relating to fuel injectors etc. I’m sure this can be directly attributed to the
addition of the Eco Systems.

My Name is Ron Gonzales, we have been offering the ECO Systems to our
customers at Bluebonnet Motors primarily as a fuel savings device. My Jeep
Wrangler did not have the performance that I like to have getting in out of traffic, I
was about to trade the vehicle when Don with ECO Systems told me about
the performance enhancement that the ECO System could provide. I was skeptical about
it making a significant difference in performance, but I have to admit it has made
enough of a difference for me to keep the vehicle. I was mainly interested in the
performance, but as an added bonus my fuel economy has increased by 2 MPG.

Red McCombs Ford
As Shop Foreman for Red McCombs Ford located in San Antonio. I was asked to
test the ECO System for our company to see if it would be something that we would
like to offer our customers. I have to say I was skeptical at first; I installed the device
on my 1997 Ford Power Stroke. Before installing the ECO 3 the truck had a turbo lag
and smoked considerably under hard acceleration. After installing the ECO 3 the
turbo lag went away and I had instant acceleration and you can hardly even notice
any smoke, my bumper no longer has any exhaust build up, it stays clean. My fuel
mileage has increased by 1.5 to 2 MPG more city driving and my highway mileage
has improved form 17 to 20 MPG. Needless to say the ECO System passed the test
and it’s now available at Red McCombs Ford.

When Don walked into the service department trying to sell this "snake oil" I was
certain of his ultimate failure. The possibility of increasing fuels volatility (fuels
tendency to vaporize) by installing the ECO System on the fuel rail prior to the
injectors, just didn't fit the "mechanical bill". After extensive back-and-forth technical
banter, Don asked if I would like to give it a try. Knowing that my 2007 Jeep Wrangler
had a characteristic throttle lag and slow curve response, especially in third gear, I
took him up on the offer with intent to prove my point - by proving him wrong. After
the installation we took a little drive. The Jeep, never meant to be a powerhouse, was
behaving like one. In a feeble attempt to save face, I drove circles in the back lot
trying to duplicate previous faltering. Needless to say, I had to swallow my pride and
admit defeat. Volatility obviously increased. Though I have yet to check the fuel
mileage, if RVP (Reid vapor pressure) has increased, conversely less fuel is wasted,
and washing of the cylinder walls averted.

P.S... - At this point it wouldn't be fair to check MPG. My right foot seems to be heavier.
