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 construction sector, diesel-powered equipment such as backhoes, loaders, tractors, excavators, and dump trucks often operates under intermittent duty cycles, with frequent start-stop conditions and extended idle or storage periods. This operating profile increases exposure to fuel degradation, especially in biodiesel blends, which are more vulnerable to instability during prolonged storage. As a result, construction companies may face hard starts, clogged filters, injector deposits, reduced equipment reliability, higher maintenance frequency, and unexpected downtime at critical stages of the project.

In construction operations, equipment availability and reliability are essential to maintaining productivity, meeting deadlines, and controlling operating costs. Poor fuel quality or degraded stored diesel can negatively affect combustion efficiency, increase fuel consumption, accelerate component wear, and reduce the overall performance of heavy-duty equipment. To help preserve equipment integrity and maximize operational efficiency, Dorf Ketal offers a comprehensive fuel treatment solution designed to improve the performance of large diesel-powered machines and extend the service life of engines and key components.

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 construction 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 durability.
