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.

The power generation sector includes diesel-powered units of many types and sizes, from prime power applications to standby and backup systems. For standby generators in particular, one of the greatest challenges is maintaining diesel quality during extended storage periods while ensuring immediate startup and long service life for engines and associated components. When fuel degrades in storage, operators may face hard starts, delayed response, clogged filters, deposit formation, corrosion, reduced combustion efficiency, and unplanned maintenance—problems that can directly compromise system reliability when power is needed most.

In critical energy applications, generator performance cannot be uncertain. Hospitals, data centers, industrial facilities, commercial buildings, and remote operations depend on reliable power generation systems that start immediately and operate consistently under load. Poor fuel condition can reduce generator readiness, increase maintenance frequency, shorten equipment life, and raise total operating costs.

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 standby and backup power systems. These additives help keep fuel systems clean, protect against corrosion, control contamination caused by bacteria and fungi, and reduce deposit formation that can impair generator performance and dependability.
