Diesel Exhaust Fluid (DEF) is a non-hazardous fluid that reduces harmful diesel exhaust emissions. DEF is a combination of two parts water and one part Urea (fertilizer). Diesel engines with (SCR) engine technology produced after 2010 require DEF to meet EPA guidelines. The benefits of using DEF include lower emissions equal a cleaner environment, and that is good for everyone. In addition, fleet vehicles using DEF and SCR technology could see a fuel savings of around 5% compared to similar 2007 models.

Need DEF? Here is how Jacobus Energy can help you:

Mobile Delivery (Truck-to-Truck)


Jacobus Energy dispenses DEF using a closed-loop system. This means that the fluid is not at risk for possible contamination from the point of manufacture to the point of delivery to the customer. This reduces the customer’s risk of voided engine warranties and costly mechanical repairs.

Packaged DEF


For customers who want DEF on-site, packaged DEF is available in 
totes (330 gallons), drums (55 gallons), or smaller containers (2.5 gallons).
