Second Brazilian Sugar Miller CORURIPE S/A Begins Use of O2Diesel(TM)

O2Diesel Corp. (AMEX: OTD), a pioneer in the development of a cost-effective, cleaner burning diesel fuel for centrally fueled fleets, today announced that USINA CORURIPE AÇUCAR E ÁLCOOL S/A (CORURIPE), one of Brazil's leading sugar and ethanol producers, has begun using O2Diesel's proprietary ethanol-diesel fuel blend, known as O2Diesel(TM), in its 300-vehicle truck fleet.

CORURIPE is the second largest agricultural group after COSAN S/A to use O2Diesel(TM) fuel in a pilot program. CORURIPE processes more than 13 million tons of sugar cane per year in its four mills located in the Brazilian states of Minas Gerais and Alagoas.

CORURIPE is fueling an initial 10-vehicle pilot fleet in its mill located at Iturama, Minas Gerais and plans to use O2Diesel™ in all of its mills after the conclusion of the three-month test. CORURIPE's 300 diesel powered vehicles consume around 4 million gallons of diesel fuel per year. CORURIPE blends O2Diesel™ fuel in its own tank farm thereby benefiting from significant fuel cost savings as well as emissions reductions.

Brazil is the world's largest producer of ethanol, and every gallon of gasoline sold in the country contains a minimum of 20% of this renewable fuel which is produced from sugar cane. Ethanol has been used as a motor fuel in Brazil for over 30 years. It was noted in a recent New York Times article that over the next five years domestic ethanol consumption in Brazil is expected to increase another 50 percent to an estimated 4.5 million gallons, further emphasizing Brazil's commitment to ethanol as a motor fuel.

"O2Diesel began forging relationships in Brazil several years ago, and we are pleased to see the results of our efforts to expand O2Diesel(TM) in the Brazilian market," said Alan Rae, President and CEO of O2Diesel. "With its nearly 300 mills and more than 15,000 diesel-powered trucks, tractors, harvesters and other equipment, Brazil's sugar and ethanol industry offers outstanding marketing opportunities for O2Diesel(TM) technology."

In January 2005, O2Diesel received approval from Brazil's National Petroleum Agency ("ANP") to become the first and only government-approved alternative diesel fuel in the country.
