Diesel fuel is highly susceptible to changes in its properties due to refinery processing—particularly in the production of low-sulfur fuels—and when blended with bio-components for biodiesel production. These changes can compromise fuel stability and lead to serious operational problems, including filter plugging, injector fouling, injection pump wear, internal corrosion, and incomplete combustion, which may result in black smoke and increased carbon monoxide (CO) emissions.

In the agricultural sector, equipment reliability is critical. Tractors, harvesters, sprayers, and other diesel-powered machines are expected to operate efficiently under demanding conditions, often during narrow planting and harvesting windows where unplanned downtime can have significant operational and financial consequences. Poor fuel quality or degraded stored diesel can lead to hard starts, loss of power, increased fuel consumption, higher maintenance frequency, and premature component wear—directly affecting field productivity and equipment availability.

To maintain equipment integrity and maximize operational efficiency, Dorf Ketal offers a portfolio of fuel treatment solutions designed to improve the performance of hydrocarbon-fueled equipment. When properly applied, these solutions help preserve engine condition, protect critical fuel system components, and extend the service life of engines and replacement parts.

Through highly effective detergent, corrosion-inhibiting, and antimicrobial functionalities, Milex® PX Series performance additives address the primary problems associated with diesel stored for extended periods—a common condition in agricultural operations. These additives help keep fuel systems clean, protect against corrosion, control contamination caused by bacteria and fungi, and reduce deposit formation that can impair engine performance and reliability.
