Specialized DEF Supply Programs Make Life Easier for Fleet Managers

Many commercial vehicles today are designed and required by law to use diesel exhaust fluid that helps reduce environmentally harmful emissions. When the diesel engine of a truck is set to use a relatively lean fuel ratio, it will produce less of the soot and byproducts that used to be so typical of this type of combustion. Unfortunately, that precaution also leads, by default, to the generation of nitrogen oxide that contributes to smog and other localized environmental problems.

Injecting diesel exhaust fluid, often referred to as "DEF," into the system can cut down on this latter type of undesirable emission significantly. With many or most commercial vehicles that consume diesel fuel now being required to adopt this approach, fleet managers find themselves needing to make appropriate arrangements. In most cases, using a DEF supply service like the BlueDEF program offered by PEAKHD will make things far easier.

A Formidable Challenge for Many Fleet Managers Today

Fleet managers are used to arranging for supplies of mission-critical consumable substances of various kinds. While certain important assets like diesel fuel itself can be obtained, stored, and dispensed in a straightforward fashion, DEF presents some unique challenges.


In order to perform as designed and as required by law, DEF must be added to vehicles while very pure and of high quality. Unfortunately, the highly reactive nature of the urea that allows DEF to bind to nitrogen oxide also makes it particular vulnerable to contamination.

Even a top-quality supply of DEF, in fact, can easily be ruined or degraded at virtually any moment. Many DEF-related problems occur during transportation, when environmental hazards of various kinds can end up contaminating an entire supply at once.

Otherwise, DEF can just as well become contaminated when kept in storage without effective precautions being taken. Containers which might be entirely appropriate for other types of materials will often not provide the protection that DEF needs to remain pure while being stored.

Finally, DEF can easily take on contaminants even while being dispensed to particular vehicles. All of these hazards combine to create a situation fraught with difficulties for the average fleet manager.

A Simple Way to Obtain All the DEF Any Fleet Needs

In many cases, it will be much easier for a fleet manager to simply sign on with a service that accounts for all these possible issues and others. That consistently proves to be the best way to ensure that a fleet will be provided with all the pure, top-quality DEF that it needs to remain compliant with every relevant regulation.
