Literally running on vapor! -over 900 mpg on Coleman camping fuel, or white gas

John 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.

The Geo Storm was a sport compact car manufactured by Isuzu and sold in the United States by General Motors from 1990 through 1993 as part of GM’s Geo line of inexpensive automobiles. The same vehicles, with minor variations, were sold in Canada in the 1992 & 1993 model years only. The Storm was intended to be a budget car with the look and feel of a sports car. The GSi version from these years … included a larger 1.8 L 140 hp engine. Autoweek’s 1990 review of the storm was titled “Slick, Quick And Inexpensive”.

John Weston: “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 local TV station NBC-2 a version of his air vapor flow system where instead of liquid fuel, only vapors go to the engine. “They used to say, ‘Hey I’m running on empty’ or ‘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. (see photos below)

By Ovidiu on July 17th, 2008:
The NBC reporters were 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.

“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, each of the different fuels had a different air/vapor mixture setting for the engine to run smoothly.  While idling, and during acceleration, the mixture for fuel had to be compensated for.” “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.” It is common knowledge among amateur car fanatics that the car computer systems are programmed to deliver 15% less fuel efficiency than is possible by enriching the gas mixture beyond what is actually needed.

Here’s a DIY page they share:   run your car on vapors


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. (see our “Run Your Car On Vapors” page)

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.” [see Reg Tech Inc. below]

A small, plastic tank
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.”

still, very crude, manual, operation
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.

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.

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.


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 industry expresses its standard disapproval [to keep us from trying it for ourselves and discovering the truth.]

“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.
