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 mining operations, diesel-powered equipment is exposed to demanding operating conditions, long working hours, heavy loads, and harsh environments. Haul trucks, loaders, excavators, drills, and support vehicles must deliver consistent performance under extreme conditions, where unexpected downtime can severely affect productivity, maintenance planning, and operating costs. When diesel quality deteriorates—especially after extended storage periods—operators may face hard starts, injector and filter deposits, corrosion, reduced combustion efficiency, higher fuel consumption, and premature wear of critical engine and fuel system components.

To preserve equipment integrity and maximize operational efficiency in mining applications, 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. This is especially important in mining, where equipment reliability, fuel efficiency, and asset protection directly influence production targets and cost control.
