Cleaning Up Avgas: Company Designs Less-Expensive Alternative Product Conceived
As Renewable Replacement for 100LL

A new general aviation
fuel claiming to be less expensive, fuel-efficient and
environmentally friendlier than any on the market was unveiled this
week by Swift Enterprises of West Lafayette, IN.

Data on Swift Enterprises' 100 percent renewable general
aviation fuel was presented April 28 at an annual meeting of an
international committee that oversees aviation fuel standards.
Unlike current biomass fuels, the product named SwiftFuel, is
comprised of synthetic hydrocarbons derived from biomass.
Co-founder John Rusek said it can provide an effective range
(distance between refueling) greater than petroleum while its
projected cost is half the current petroleu m manufacturing
cost.

The fuel created by Swift Enterprises' propulsion and energy
researchers meets or exceeds the standards for aviation fuel as
verified by nationally recognized laboratories, said Rusek, a
professor in Purdue University's School of Astronautics and
Aeronautics Engineering.

Swift Enterprises, founded seven years ago at Purdue Research
Park, is led by Rusek and his wife, Mary, who have been involved in
the field of energy more than two decades. The meeting was held by
the Coordinating Research Council of ASTM International in
Alexandria, Va. ASTM International is one of the largest voluntary
standards development organizations in the world.

"Our fuel should not be confused with first-generation bio-fuels
like E-85, which don't compete well right now with petroleum,"
Rusek said. "For general aviation aircraft, range is paramount. Not
only can our fuel seamlessly replace the aviation industr y's
standard petroleum fuel, it can outperform it."

The general aviation
industry each year uses nearly 570 million gallons of 100LL
aviation fuel, which contains lead, is becoming increasingly
expensive and is non-renewable. In contrast, testing has shown
SwiftFuel is 15 to 20 percent more fuel efficient, has no sulfur
emissions, requires no stabilizers; has a 30-degree lower freezing
point, introduces no new carbon emissions, and is lead-free, John
Rusek said. In addition, he said, the components of this fuel can
be formulated into a replacement for jet/turbine fuels.

The aviation industry has been the only form of transportation
to use leaded fuel (tetraethyl lead) since an Environmental
Protection Agency ban went into effect 30 years ago. However, that
lead-free exemption will cease in less than two years.

"The general aviation industry, both domestic and foreign, is
demanding a solution to this dilemma ," said Mary Rusek, Swift
Enterprises' president. "Our new, patented technology can provide
the 1.8 million gallons per day required by the industry in the US
by utilizing only 5 percent of this country's existing bio-fuel
plant infrastructure."

Swift Enterprises officials are in discussions with the Federal
Aviation Administration, which has initiated a cooperative
agreement with the company to evaluate the fuel.
