Car gets 400+ MPGJohn Weston stands next to his 1992 Geo Storm GSI, which is equipped with his invention dubbed the Air Vapor Flow System. He claims the car can run 14 miles on 4 ounces of fuel, which means it runs with extreme fuel efficiency at more than 400 miles per gallon.
His car got 463 MPG and ran on fumes
John Weston’s Air/Vapor Flow System, AVFS -- Literally running on vapor!
John Weston’s 1992 Geo Storm: “Since I changed the fuel system unit, it’s drastically different. I disconnected the fuel line from the injector so no liquid goes to the engine,” said Weston. Weston showed NBC-2 a version of his air vapor flow system where instead of liquid fuel, only vapors go to the engine. [ "run your car on vapors" ] “They used to say, ‘Hey I’m running on empty. I’m running on fumes.’ Well, this is actually running on fumes,” he said. Weston says the system burns cleaner and also made a bold claim about fuel efficiency from a one-time test. “It came up to 463 miles a gallon if we had driven in the same manner – a gallon,” said Weston.
“I drove from here to Fort Myers, and I’m up there keeping up with traffic running 80 mph. ” Now, the backyard mechanic is looking for investors so he can eventually take his invention public. In the meantime, he says you might see his car on the highway.” He also put his vaporizer on a generator, a riding lawnmower, and his motorcycle. which are all so much more “fuel efficient” now!
By Ovidiu on July 17th, 2008 :
The NBC reporters were even taken on a test drive, where the engine stumbled a little bit and John said he put too much vapor on the pipe, so when he lowered the vapors, everything got back to normal.
NBC-2 relates that John Weston is waiting for investors, because he wants to sell his invention so the whole world benefits from it. . . .
“I learned that when using the AVFS [Air & Vapor Flow System] on my Geo Storm by using the standard 87 octane gasoline, then 89 octane, then used Coleman fuel(for lanterns), then charcoal lighter fluid and even rubbing alcohol. On each of the different fuels there was a different setting of the “air/vapor” mixture for the engine to run smoothly. Not only at idle, but on acceleration as well. I did NOT change timing or bypass any of the original sensors that are factory installed on our vehicles now-a-days.” – John Weston
“Based on talks with actual engineers that work at Ford and GM, these two companies have actively discouraged any improvements in fuel efficiencies. Engineers would be threatened if they were caught tinkering with the computer systems or searching for ways to make the car engines run more efficiently.”
Maybe if enough people offered to pay him to install one on their vehicle (boat? … around Port Charlotte) he could actually make some money from it, and if there is a self-serve-garage “rent-a-bay” in Port Charlotte you/he can rent for a few hours.
Under the hood of John’s extremely fuel efficient car
Notice the white container with about a half inch of gasoline in the bottom and an extra pipe with a valve to allow him to adjust the amount of extra air (to control the air/vapor mixture).
It can also be seen the the air filter was in the area now occupied by his vapor system. Running without an air filter may be o.k. for a while – certainly long enough to do a few test drives and measure the rate of fuel consumption, but in the long run, an air filter will be needed.

Charlotte Sun
October 9, 2007
If John Weston of Port Charlotte can get investors to take his gas-saving invention to the global automotive market, it just might solve the problems of smog, global warming and the high cost of foreign oil. It also might prove that human potential is not limited by education or socioeconomic status.
Weston, 48, who dropped out of high school as a 10th-grader but later achieved a GED, claims to have invented a device that can turn virtually any car into a gas-miser that can run as far as 500 miles on a single gallon.
Called the Air Vapor Flow System, or AVFS, the device functions by vaporizing gasoline before it gets inducted into the engine. That saves fuel and reduces pollution because it allows the engine to burn more of the fuel that gets sucked into the combustion chamber, he contends. The device works on small, industrial engines or larger automobile engines regardless of whether they have carburetors or fuel injection systems, according to Weston.
Weston has been working to bring a prototype of the invention into more advanced development since the late 1990s. After encountering some financial difficulties in recent months, Weston is now renewing efforts to find investors.
“My setback has always been financial,” Weston said. “That’s why I’m totally open to sponsors, investors or purchasers.”
The device consists of a small, plastic tank that gets mounted under the hood of a car. Some hoses from the engine’s air intake housing are run to the top of the tank so that the engine draws in vapors from above the level of the liquid gasoline.
In an impromptu demonstration conducted for this reporter last week, Weston installed one of the devices into his battered 1992 Geo Storm. Weston’s car ran well on the vapors from the device when the level of the liquid in the tank was within a certain margin. The engine ran either too rich or too lean when the level was above or below that margin. The car traveled 14.8 miles on about 4 ounces of gasoline during the test. If accurate, that would amount to about 473 miles per gallon.
Weston’s neighbor, retired construction contractor William “Pops” Gavel, said he witnessed an even more dramatic experiment conducted by Weston. Gavel said he rode as passenger in Weston’s car for 28.7 miles — from Weston’s house to a location in Englewood — on just 4 ounces of Coleman camping fuel, or white gas. If accurate, that rate would be equivalent to 918 miles per gallon. Gavel said he watched Weston pour the 4 ounces into the tank and checked the mileage on the odometer himself.
“I couldn’t believe it,” said Gavel. “I said, ‘Wire me up!’ I’ve got a Ford V-8 whacking down a gallon every 17 miles and I thought, gee, I could drive all day with that kind of mileage.”
To operate the engine, once the fuel level dropped below its optimal margin, Weston briefly triggered a home-made switch 15 times. That pumped in additional fuel from his car’s regular fuel tank. The switch was made from a lamp cord. It was triggered by pushing the two prongs of the plug together for a split second. After the test,
Weston estimated the amount of gasoline consumed by measuring the amount of gasoline that was added from his car’s regular fuel tank. To do that, he again triggered the homemade switch 15 times, this time pumping fuel into a measuring cup. The fuel measured 4 ounces.
“Right now, it’s looking like a Mickey-Mouse backyard setup, but regardless of the way it looks, it functions,” he said.
*** John Weston and his generator with his AVFS
Also yet to be perfected are ways to maintain the level of liquid fuel in the vapor tank, and a way to adjust the mix of air and vapor while driving.
Weston recently tested one of his AVFS tanks on a gasoline-powered utility generator. Without the device, the generator ran for 3.5 hours. With the device, it ran for 14 hours on the same amount of fuel, he said. [a 400% improvement]
School of hard knocks
Hailing from Connersville, Ind., Weston attended 23 schools in 10 grades before dropping out. He explained his father, a construction worker, moved the family often, in both Indiana and Florida. “I could not afford to take vehicles in to get repaired,” he recalled. “I could afford only to buy a Chilton’s manual and repair them myself.”
After working as a welder on oil rigs off Louisiana, he returned to Indiana to care for his ailing mother.
The breakthrough came after Weston, who routinely smokes cigarettes while working on his engines, needed to peer into the gas tank of a lawn mower engine. It was dark in the tank.
“I didn’t have a flashlight at the time, so I used a lighter,” he recalled.
Suddenly, a blast of flame blew out of the tank. Weston immediately realized the potential.
“I said, ‘Wow, let me try this,’” he said.
Weston grabbed a piece of tailpipe and stuck one into a carburetor and the other into a five-gallon gas can. The engine ran for a few moments on the vapors from the can, he said.
In 1996, a school teacher in his hometown invested $12,000 to help Weston fashion a working prototype. The teacher, Edward Slaybaugh of Connserville, Ind., said he considered the invention “the greatest boon this century.” “I hope some good comes of it,” Slaybaugh said Friday.
Reg Tech Inc.
In 1997, Weston sold the rights to his invention to Reg Tech Inc. and its subsidiary, Regi U.S., of British Columbia, Canada.
Slaybaugh said he was compensated for his investment with Reg Tech stock, which he still holds. The company is currently working to develop a lightweight rotary engine.
Weston’s deal called for the two Canadian firms to pay him $100,000 cash, $400,000 in stock, plus royalties. If the companies never turned the device into a commercial product, the company would still have to pay Weston $24,000 per year for 21 years under the contract.
The company had the AVFS tested on a small engine by the firm Adiabatics Inc. in Columbus, Ind. The results showed it reduced hydrocarbons 71 percent and carbon monoxide 25 percent. The rate of fuel consumption was reduced by 15 percent to 30 percent. But the device increased emissions of carbon dioxide 12 percent and nitrogen oxides 296 percent. Those are greenhouse and smog pollutants.
Weston said those emissions increased because Reg Tech’s engineer failed to properly adjust the vapor/air mixture. “Not all engineers are mechanics,” Weston said.
In 2002, Reg Tech relinquished the rights to the invention back to him.
John Robertson, Reg Tech president, said in a phone interview last month the company’s patent attorney had advised the firm that Weston’s invention was “unpatentable” because it was “not unique.” Apparently, a similar system may have been used in race cars in years past, Robertson said.
The company dropped the invention because it would have been unwise to invest in it without the protection of a patent, Robertson said.
“It runs, but somebody’s got to have a sophisticated testing apparatus to develop it,” he added.
A riding lawnmower running on vapor
John’s riding lawnmower running very very efficiently on vapor – notice, again, that the 1 small bottle produces too much vapor and he has to dilute it by joining a second pipe of air into the mixture (white with a red valve). See a smaller bottle of fumes powering his – very fuel efficient – motorcycle, below.
“The automotive industry has made strides in the past 10 years to make cars that produce less of such smog gases as hydrocarbons, carbon monoxide and nitrogen oxides, said Jim Kliesch, senior analyst for clean vehicles at the Union of Concerned Scientists. [no, they have fought long and hard, in the courts and in Washington, against making any improvements!]
If a vaporization device such as Weston’s improved mileage to the levels that Weston claims, that would reduce gases contributing to global warming, said Kliesch. [an open recognition that Reg Tech's testing through Adiabatics must have been flawed when claiming an increase in carbon dioxide and nitrogen]
“It sounds intriguing,” added John Cabaniss, director of environment and energy issues for the Association of International Automobile Manufacturers.

December 2007 :
THE AVFSHi,
My name is John Weston, the inventor of a fuel system called the Air/Vapor Flow System, referred to as AVFS, and would like to present this to everyone who is into automotive, energy saving systems, environment and new ideas that are a benefit to our society. Not to mention our economy, since the AVFS has been proven to get 14.8 miles on 4oz of 87octane gasoline, witnessed by Mr. Greg Martin, a reporter for the Charlotte Sun-Herald of Port Charlotte Florida.
I developed the AVFS to operate an engine on the gasoline vapors which eliminates liquid gasoline from going to the engine. This does away with any unburned fuel in the exhaust (meaning no need for the EGR system) and reduces the emissions by up to 70% and possibly even more now (since I am doing further R&D).
With the reporter riding along with me when he was doing the story on the AVFS in the local news paper, we were able to drive 14.8 miles on 4 oz. of liquid gasoline going to the AVFS tank that I had developed and adapted to the 1992 GEO Storm GSI, using the simple materials I was able to afford at the time, being some pvc tubing and fittings, some electrical conduit tubing and a plastic tank that was actually manufactured to be a tank for windshield washer fluid. That added up to be about 460 miles of driving if we had gone through a gallon of gasoline during the ride for proving that the AVFS does actually work and was being witnessed by the reporter so he would be able to be honestly writing a true story.
My reason, hopes and desires for presenting the AVFS in this manner is that perhaps someone would be willing to either come here or have me brought to his/her facility or business, regardless of small or large selection of automobiles or equipment operated by gasoline engines, and give someone the opportunity to see it function in person, on any vehicle chosen to have the AVFS adapted to, the aspects of the AVFS and perhaps present it or assist financially as a means of helping get the AVFS in use for the sake of our environment, economy, energy savings and ability to stop buying so much oil from out of our country....
I did file a patent registration on it before presenting it to others. Plus, being a certified paralegal helped to put together several other AGREEMENTS that are signed before others are shown the whole working of the AVFS. I am hoping this will reach some people who will be able and interested in sponsoring or investing soon.
Hate to say, but am at a financial stand still currently and open for sponsorship(s) from $10.00 and up. Even small amounts help in big ways.
Sincerely,
John Weston

Charlotte County Man Claims to Get 463 MPG with Car Running on Fuel Vapors
by Ovidiu Sandru
Have your ever run your car on “fumes”? They’re gas vapors that form when it evaporates. One man, John Weston, from Charlotte County, FL, has found these fumes useful and made a fueling system out of them so his car gets an incredible mileage: 463 miles per gallon! In European measurements (if I’m correct) this is 0.8L/100km!!! Wow!
Not even VW’s latest gadget car can’t get this mileage!
John has found by trial and error the method to get the fuel vapors “inhaled” by the engine. He cut the fuel injector lines in his 1992 Geo Storm and adapted the whole thing to run on fuel vapors.
In an interview he gave to NBC-2, John Weston states: “It came up to 463 miles a gallon if we had driven in the same manner – a gallon. I drove from here to Fort Myers, and I’m up there keeping up with traffic running 80 mph.” The NBC reporters were even took to a test drive, where the engine stumbled a little bit and John said he put too much vapor on the pipe, so when he lowered the vapors, everything got back to normal.
Some mechanics say that disconnecting the fuel lines and not feeding the engine with regular liquid fuel will eventually ruin it. It may be so, but precautions can be taken and proper oiling can be made so the engine is well-lubricated. The same thing applies to natural gas-converted cars, and they run smoothly forever (it’s only gas, not oil). I don’t know much about mechanics, but if you find a system that gets you 463mpg, you’re also smart enough to find a proper lubrication system.
NBC-2 relates that John Weston is waiting for investors, because he wants to sell his invention so the whole world benefits from it. I keep thinking about hoaxes in the energy industry. Some solutions are too simple and too mainstream-published to be hoaxes. There are also law prosecutions for that matter. I don’t know. It remains to be seen. In the meanwhile, it’s a great idea having this mileage. If that car can run on nothing else but gasoline vapors, an idea pops into my mind: why wouldn’t a car run on hydrogen, for instance? Skeptics say you need a lot of hydrogen (much more than you can obviously produce on-demand). Is it true you do need that much?
A complaint :
John Weston what do you think? A story always has two sides. You have now a chance to explain your self.
The short version of my story is that the AVFS, can not and will not work. I send it back to you as agreed. You have not paid me. It was delivered the 19. of August. Your promise that it would work was false. What you where good at was fooling me.
I will of course not give a short testimonial on the website. I will have all of our emails and all my videos, and all my explanations why the AVFS can not work.
Where I come from, Norway, Scammers get locked up.

Hello John,
I think it is a really great idea... For just as you read what Robert has told you in his email; that just twenty feet away from him are two engines running on vapor to his great delight. He also went on to tell you that there are things that do make a difference in the adjustment of the air/vapor mixture valve----- things I told you all along. As well as stating ; "do not heat the bubbler or the fuel". The ambient air under the hood of a vehicle prevents the unit from becoming too cold to operate; as mentioned by Robert in stating that the problem occurs when the fuel within the unit gets too cold for proper vapor being provided. Robert is telling you the same things that I told you from the beginning of our conversation about the AVFS. I repeatedly told you that there are many variances when adapting to a vehicle and that specific steps must be adhered to. You, on the other hand have many different connections and apparatus under the hood of your vehicle---- the "octopus", different ignition system and other components. These things made it more difficult to determine the reason you were experiencing the difficulties.
Another mention of being able to assemble correctly was made by Robert concerning a different system, which goes right along with me telling you repeatedly that we must follow each and every step of the
installation in order to achieve the results we are expecting. You told me in an email (of which I,too, have kept each and every one of) that you bypassed something on more than one occasion during the installation.
In all regards and with all due respect, I do not have any problem with you going cyber ----as you called it---- about the AVFS and the problem(s) you found to have when the specific steps of the installation took place. That will help others to know that different systems do require specific instructions to be followed when doing it yourself installations of things are conducted.
Have a great day...... -- John Weston
I bought a fuel vaporizer from you for $ 2000! For that price I was promised that it would work. I am not doing research for you. Do you remember the pictures of the gasoline turning dark red after the light fumes in the gas has evaporated? That is why the AVFS can not and will not work. The AVFS is just a cold bubbeler. NOTHING MORE. We all should know that the only way to vaporize fuel is to crack it. That is done by spraying fuel on to a 900f heated element.
I was an idiot and trusted John Weston.
Would it not be a lot better for you to just pay me back the money? How can a very unhappy customer be good for your future business? Why not just log on to Paypal right now? Just pay me and move on. ... -- JA
