Neutro Fuel Additives markets two products: an oil additive and a fuel additive. So far, we've treated six bikes…a 1994 Honda VFR750 with a Two Brothers pipe and a Factory jet kit; a 1995 Yamaha YZF600R, totally stock; a 1994 Kawasaki ZX-7, also stock; a jetted and piped 1989 Yamaha FZR600; a stock 1979 Honda CBX; and finally, a 1993 KTM 250 dirtbike. All except the VFR and the FZR showed a substantial 'increase in power as seen on a Dyno-Jet 150 dynamometer. All bikes were warmed up in preparation for a baseline run. Next, a half-ounce* of oil additive was added to the crankcase of each bike. The engine was run through the gears and re-tested. Then a *half-ounce of fuel additive was put into the tank and the bike was again run through the gears. After the additives were thoroughly distributed, we did fourth-gear roll-ons to measure rear wheel horsepower.

The increase was startling for the " ZX-7. The Kawi made 97 horse power at the rear wheel in stock condition. After treating both oil and fuel, peak power rose to 102 bhp. The increase wasn't just at the top of the rpm band, but throughout the operating range, with the greatest increase seen at 7000 rpm. The ZX had shown a definite dip in its powerband. but after treatment the dip turned into a peak and horsepower went up by six. Owner Chris Lypka said his bike felt stronger particularly in the 7000-rpm range-as the dyno had shown.

The next largest increase came from the American Roadracing test YZF600R, which has always been less than a stellar performer. The YZF has been on the dyno many times, and the best it has ever done is 79 bhp quite a bit lower than the 84-85 bhp that we've seen from other YZF60ORs. Seat-of-the-pants testing verified that this Yamaha is simply not in the 90th percentile of its class. After treatment, the 600 climbed to an all-time high of 84 bhp. Riding confirms that this is definitely a happier motor, more willing to rev and making better power throughout the entire rev range.

Finally, the venerable CBX. This bike has had very little maintenance over the years, largely because it never seems to need any. With 37,000 miles on the odometer, the big Six put out 80 horsepower to the rear wheel. We chose the CBX primarily to test the oil additive, because few motors have as many moving parts and bearing surfaces. Also, the "X" has proven to be sensitive to the fuel it uses. After treatment, the 24-valve mill made five more ponies from idle to redline. Riding confirmed that it did seem to run slightly better. . . . . .As an avid Supersport fan and competitor, I'd be overjoyed to pour something in my tank that would give me an edge (particularly if it was legal!). . . . . -Michael Ross

The MMI treatment ratio was only 1/2 ounce of oil treatment per bike and 1/2 ounce of gas additive per bike. The treatment ratios are not the the treatment ration recommended by High Performance Plus. The recommended treatment ratio is 1 ounce of oil additive per engine and only 1cc of gas additive per gallon of gas. (added with an eye dropper!).

To PEXT Internationnal: Test results

I have included some additional information about analyzing emission gasses.

1. C02 without product HC's which is unburned fuel was between 10750 ppm (parts per million) to 10772 ppm which is very high.
2. C02 with product HC'S went way down between 8966 ppm to 5237 which means better fuel mileage.
    C02 dropped slightly which two strokes are never as efficient as four strokes are.
3. CO and 02 without product CO which is a rich indicator went from 16.5% to 16 .6% very little difference which means it was running rich. On a good running vehicle CO should be 3% or less.
4. C0 and 02 with product dropped down to 4.0% to 2.6%. This was a big reduction with the addition to this product.
    O2 dropped slightly between the two remember we are dealing with a carburetor and a two stroke which never were as accurate on 02 as fuel injected vehicles and four strokes.
5. CO and HC without product CO went from 16.5% to 16.6 % and HC's went from 10750 ppm to 10769 ppm.
6. CO and HC with product went way down to CO went from 3.8 % to 2.6%.  HC's went from 9000 ppm to 5200 ppm.
What this tells me is that the product reduced HC's therefore better fuel mileage and better emissions.

September 15, 1999
Arizona Automotive Institute
On September 3, 1999, I took part in a demonstration held at the Arizona Automobile Institute, which was not in any way associated with or endorsing the product being demonstrated. Arizona Automotive Institute was simply being used as a facility for testing.
The demonstration was presented by Mr. Frank Diamond.
The demonstration was to validate that a fuel additive would reduce auto emissions by 80% and improve mileage by 20% or more. Two vehicles were picked by the Institute to be tested.
One was a 1992 Ford Thunderbird, computerized fuel injected. The second was a 1983 Chevrolet full size Blazer with no computerized controls in the carburetor system. Both vehicles were mechanically sound and would easily pass emissions by the Arizona State standards.
I felt that both vehicles would put the product to one ultimate test, as their emissions were about as clean as they could possibly be. To my surprise, after disabling the air (air injection reaction) systems, which help clean up the exhaust even further in the catalytic converter, the product worked as advertised.
Hydrocarbons (fuel pollutants called HCs) went from 76 ppm (parts per million) to 2 ppm in the Ford. The Chevrolet went from 80 ppm to 7 ppm. Both vehicles produced 0% carbon monoxide (COs).
I believe that this additive if used by federal, state, and local governments as well as companies with large and small vehicle fleets would save large sums of money in fuel costs and drastically reduce emissions.
In my opinion, smog could be drastically reduced at literally no cost to the user because of the increased mileage per gallon benefits.

PRIEST CONFESSES:
A Look at some fuel additives
By "Priest'-Roger Hurm
I'd been fooling’ myself, a new big bore kit and a lighter chopper but I still felt like I was ridin' the same tired 74".. After a routine bolt tightening and push rod adjustment, Mike at Sidewinder's Cycle gave me a look I didn't recognize. His usual business-like seriousness was gone as an impish almost devilish glow flooded his face.
"I'm putting something in your gas tank,' he said smiling wickedly. His instructions went like this: "I'm putting two drops from the eye dropper in each side of your fat bobs. You're about half full -- go fill up and about 3 miles later—be careful cuz you're gonna feel it!”
He said "this is KICK ASS GAS AND IT REALLY WORKS" . Our friend Chris was listening and broke into a story about he and Mike the night before and how his acceleration was out of sight on fourth gear. "It'll give you four extra horsepower guaranteed," I heard as I started my bike.
Yeah, I nodded and smiled and headed for the gas station to top off thinking I'd take a short ride for shits and grins just to please Mike. By the time I got to the Cactus and 32nd St. intersection, a quite busy one, the motor was running perceivably smooth with a snappy note and it didn't try to kill at the light. I snapped it and began climbing through 3rd gear when pop, pop, pop - the system seemed to be dying – yet it was only momentary and I shifted to fourth - rolled on it and WOW - I had power I hadn't felt since three years before with 120+ octane aviation fuel. I turned around and made like a drag racer between 36th St. & 32nd St. on Cactus, actually wondering when an EVO might wander by so I could race 'em. With little traffic, I screamed through the gears feeling torque, power, and a crisp note humming from my drag pipes
The approach to the Cactus and 32nd St. intersection caught me off guard - I was accelerating - hit 60 and shifted to fourth gear - the crescendo building as no hesitation interrupted this powerful roll on to fourth - the unworldly horsepower in fourth caused me momentarily to not want to stop at the intersection. A wicked tickle drove my being as I for one instant felt like just not stopping. I had to fight for my senses and decelerating – found my way home.
First thing I did was call Mike at the shop - he said, "I know--it happened to us and I wanted you to share the experience." I asked if this were legal - like slanimin' your bike fulla crystal" he said, "Yup and I got it here at the shop and I got the oil treatment for you that'll give an extra two horsepower." Well I’ll tell you the rest of the story:
I got the oil changed the next day - Mike added the stuff and I did notice instant improvement over the horsepower I'd already picked up. And you can do it yourself! With an EYE DROPPER! Very potent – very cheap – hell how can a shovel head do without it!
