MDEChem DCP500 HFO MDO additive in short:

MDEChem DFC or DCP500 is an application-engineered, fuel borne HFO MDO additive technology that utilizes proprietary technology to produce EPA verified results in the areas of less damaging emissions and less diesel fuel or heavy fuel oil consumption.

When MDEChem’s HFO MDO additive is introduced into fuel, it improves the combustion process and reduces friction, increasing fuel economy while reducing emissions and engine wear. Unlike additives such as cetane enhancers, alcohols, or metal-based catalysts that seek to alter the fuel, MDEChem DFC fuel-borne technology uses the fuel as a carrier into the combustion chamber.


This HFO MDO additive is patented technology and utilizes two processes to positively impact the engine; a catalytic reaction and a surface conversion. The catalytic reaction optimizes the heat release rate, which leads to increased power, reduced emissions, and increased fuel efficiency. The surface conversion forms an inorganic polymer complex that converts the surfaces of ferrous and non-ferrous metals. This complex smoothens and passivates the metal surface, improves reflectivity (emissivity), and reduces oxygen reactivity, resulting in a reduction of friction and a more complete combustion reaction.

To ensure the highest degree of product quality, MDEChem manufactures its patented products at company owned ISO 9001-certified facilities. U.S. Patents: 5084263, 5310419, 5540788; Patents Pending.


As MDChem DCP500/DFC is a HFO MDO additive, HFO-fuelled users can order MDE’s DFC custom injection system, available for precise blending. The system is specifically designed to guarantee flawless introduction and mixture of HFO and DFC at the pressures and temperatures that HFO engines require, without, as usually seen at HFO-level, destroying the additive’s functionalities.

MDEChem DCP500/DFC causes fuel to burn more completely. Because of the use of the HFO MDO additive, the combustion temperatures rise with an average 4.6%. Already present deposits in the combustion area of the engine are removed this way.

Increased amounts of burned fuel means that more energy comes free, thus resulting in much lower fuel-consumption. Average drops in fuel consumption range from 5% to 12%, based on type, age and condition of the engine.

An increased lubricity in fuel injection system and engine makes that cold starts are improved, injectors are functioning much better for a much longer time with less wear and that the engine itself runs with less noise and smoke. All season performance of fuels using MDEChem DCP500/DFC increases as the HFO MDO additive prevents gelling of fuels down to -40 ⁰C. MDEChem DCP500/DFC does not contain harmful zinc, chlorine, alcohol, ash or heavy metals, so is safe to work with.
