SAN DIEGO--(BUSINESS WIRE)--Aug. 20, 2002

Green Star Products, Inc. (OTC:GSPI), formerly BAT International, Inc., has just completed an independently verified test run of a high mileage "SuperCar" that achieved 99 miles per gallon (99 MPG).

The two-door 1994 Geo Metro completed a set of laps around the California Speedway on 8/19/02 traveling at a 45 mph constant speed to evaluate the effects of several products including a special Spiro Exhaust device, SuperBAT TVT Anti-Friction Metal Treatment lubricants and Green Star(TM) Bio-Fuel. The run provided an excellent opportunity to evaluate how various GSPI products now entering the market could work together to achieve an overall fuel efficiency goal. The Geo Metro had a standard diesel engine (3 cylinder Kabota), so that most fuel efficiency improvements were the result of the exhaust, lubricants and a high efficiency biodiesel fuel.

The run was certified by a set of independent consultants including a consultant in the petroleum industry and other independent parties. Measuring a difference in volume of the fuel after a 10-lap run on the 2-mile-long circuit verified the fuel economy. Speed was verified by timing every lap. The media were also in attendance, including a representative of the local newspaper The San Bernardino Sun.

The very high fuel efficiency goal was achieved using a very low-tech car and engine that was coupled with high-tech aftermarket products. The test was intended to provide data on how several products that improve fuel efficiency and/or lower pollution would work together to achieve a combined fuel efficiency result. The products included:

Green Star Bio-Fuel:   Biodiesel, a renewable & biodegradable
                       alternative fuel produced by American
                       Bio-Fuels, coupled with the additive "Viscon"
                       to further improve fuel efficiency & lower
                       emissions (typical fuel efficiency gains are
                       from 10-20%). American Bio-Fuels, an affiliate
                       company of GSPI, will be announcing plans for
                       broad scale introduction of "Green Star"
                       Biodiesel in several California Air Districts.

SuperBAT TVT:          SuperBAT's TVT Anti-Friction Metal Treatment
                       Lubricants were used in the engine,
                       differential and manual transmission to reduce
                       friction, improve fuel efficiency (typically
                       by about 3 to 8%) and extend engine life.
                       SuperBAT, a subsidiary of GSPI, will be
                       announcing continuing market efforts in
                       industrial and export markets and a new
                       initiative to introduce TVT in the U.S. racing
                       industry and retail markets. The TVT lubricant
                       additive is an advanced biodegradable formula
                       in competition with other non-biodegradable
                       anti-friction additives seen in late night TV
                       infomercials.

Spiro Exhaust System:  Dolphin Automobile Co. (Dolphin ACI), an
                       affiliate company of GSPI, has been developing
                       advanced diesel exhaust retrofit devices to
                       improve fuel efficiency of diesel engines
                       (typically by about 4 to 10%). The technology
                       improves "breathing" of the engine through
                       changes in air circulation in the exhaust
                       system. Details about the technology will be
                       discussed in an upcoming release.

The original purpose of the run was to complete testing of a vehicle GSPI is planning to send to the Michelin Challenge Bibendum 2002 (sponsored by the Michelin Tire Co.) that is scheduled for September 22-26, 2002, in Germany and France. The vehicle GSPI was planning to send, a 1998 Geo Metro Hatchback with a turbocharged, intercooled Yanmar 3-cylinder engine, had some last-minute problems with the gears in the transmission. The transmission could not be repaired in time to participate in the run. Since GSPI was already committed to track time at the California Speedway, we had to quickly put on line the backup 1994 Geo Metro. The 1994 Geo Metro has a naturally aspirated diesel engine with a pre-combustion chamber and mechanical timing and has no turbo charging or intercooling.

Note: Both of these engines are in marked contrast to other super-efficient vehicles. The most efficient vehicle in Europe, the Audi A2, has a lighter and more aerodynamic body, a TDI engine with electronic timing, direct injection intercooled with a turbocharger and the latest engine technology. The Audi A2 achieved an average of 95 miles per gallon in a constant speed test last year going 42 miles per hour.

This makes the GSPI run particularly significant, since we achieved almost a 5% improvement over this result of the Audi A2 at a higher speed using 8-year-old engine technology with most of the fuel efficiency gains from the Spiro Exhaust, SuperBAT TVT lubricants and Green Star(TM) biodiesel fuel.

An additional set of runs are planned once the 1998 Geo Metro transmission is repaired to determine fuel efficiency with a more modern engine and the same Green Star biodiesel fuel, TVT lubricants and exhaust device. The runs will also be at a similar speed to duplicate the fuel efficiency test requirements for the Michelin Challenge Bibendum 2002 to determine the expected results in lap tests in Germany. A final decision about participation in the European event will be made following up on these performance tests in the next two weeks and after considering other scheduling issues.
