MDEChem Details Results of the U.S. EPA ETV Test on EnviroFuels Diesel Fuel Catalyzer.

HOUSTON -- MDEChem, Inc. (PINK SHEETS:MDKM) a Research and Development Company is pleased to provide a summary analysis of the U.S., EPA ETV (Environmental Technology Verification) program related to testing of EnviroFuels Diesel Fuel Catalyzer. The ETV Report definitively demonstrates that EnviroFuels Diesel Fuel Catalyzer (DFC) reduces fuel consumption and harmful pollution emissions, a significant breakthrough in the industry.

ETV VERIFIED FUEL CONSUMPTION REDUCTIONS IN AN EMD 16-645E3 ENGINE

Line Haul Duty 5%                      Switching Duty: 10%

ETV EMISSIONS REDUCTIONS IN AN EMD 16-645E3 ENGINE

Line Haul Duty                         Switching Duty

CO2 emissions: 5%                      CO2 emissions: 10%
CO emissions: 44%                      CO emissions: 39%
THC emissions: 22%                     THC emissions: 27%
                                       NOx emissions: 9%

"TECHNOLOGY PERFORMANCE (the report concludes)

...Brake-specific fuel consumption (BSFC) and brake specific gaseous emissions showed statistically significant improvements at the majority of operating notches. Line-haul duty cycle-weighted BSFC and gaseous emissions also improved. Switch duty cycle-weighted (BSFC) and all gaseous emissions showed statistically significant improvements."

EnviroFuels manufactures and markets the first stand alone, patented and EPA-verified fuel technology that reduces greenhouse gas emissions and improves diesel engine fuel economy and performance in large reciprocating engines.

Envirofuels Diesel Fuel Catalyzer (DFC) is an application-engineered chemical compound that creates both catalytic and surface-conversion reactions within diesel-engine combustion chambers. These reactions reduce the coefficient of friction and oxidation-related energy loss and optimize the heat-release rate during combustion.

Since Envirofuels, LP purchased the intellectual property rights from MDEChem in 2002 it has been perfecting the patents to protect the technology for use globally.

Envirofuels has standardized production and formulation of the MDEChem developed Diesel Fuel Catalyzer.

In addition to the U.S. EPA ETV testing EnviroFuels L.P. has been conducting successful tests with short line railroads over the last 22 months.

MDEChem owns a 16% percent interest in Envirofuels, LP. The Limited Partnership Agreement between Envirofuels, L.P. and MDEChem, Inc. dated December 10, 2002 provides that Envirofuels during the initial seven (7) year term of the Partnership will pay MDEChem a technology fee in the amount of ten percent (10%) of the annual net income of the Envirofuels.

"The marketing opportunities for Envirofuels DFC are staggering," stated MDEChem's President and CEO Paul Sack, with the use of the DFC, the customer can expect the following benefits with an overall reduction in capital spent on fuel + DFC verses fuel only without DFC.

- Lower Fuels Requirement

--Reduced Exhaust Gas Temperatures

--Reduced Carbon Deposits

--Lower Coefficient of Friction

--Reduced Opacity

--Reduced emissions

--Reduced engine maintenance

DFC contains NO heavy metals.
