What is Diesel Exhaust Fluid (DEF)

Diesel Exhaust Fluid (DEF) is a specially formulated solution designed to reduce harmful emissions produced by diesel engines and must be handled carefully to maintain its purity. It is a clear, non-toxic solution made up of 32.5% urea and 67.5% deionized water. When used properly, DEF can reduce nitrogen oxide (NOx) emissions by up to 90%. In addition to its environmental benefits, DEF also plays an essential role in maintaining the performance and longevity of your fleet’s emissions system.
Energie Fuel’s DEF replenishment services ensure careful, reliable DEF supply at every step. When filling a vehicle’s DEF tank, our drivers inspect the DEF nozzle and inlet opening to confirm they are free from dust, crystals, or other contaminants. If buildup or contamination appears, they gently clean the area using a non-corrosive, water-based cleaner before dispensing DEF.

Because DEF requires strict handling, Energie Fuel follows two key standards for every DEF product we supply.

  1. We only provide DEF that meets International Organization for Standardization (ISO) requirements, including ISO 22241 and ISO 22241-1.
  2. We exclusively distribute DEF using Micro Matic closed-container systems to preserve product purity and prevent contamination.

As a result, the DEF we supply maintains its integrity and stays protected from impurities. In addition, our closed-container system provides tamper evidence and helps support DEF system warranty compliance.

Only diesel engines equipped with Selective Catalytic Reduction (SCR) systems require Diesel Exhaust Fluid (DEF). In general, most on-road diesel vehicles built after 2010 use SCR technology to meet emissions regulations. However, older diesel engines (along with some off-road and specialty equipment) may not require DEF.

What are the sizes offered?

We offer DEF in 2.5-gallon jugs in half pallets or full pallets, 55-gallon drums, 275-gallon totes, and 330-gallon totes.

How can I schedule delivery?

We work directly with your company to develop a scheduling system that best fits your operational needs. Energie Fuel Group delivers bulk DEF directly to your location, secured yard, or job site for fleets throughout Southern California.

Where can you deliver?

We deliver DEF throughout San Diego County and all the way up to Fresno, California. Our service area also extends east up to Las Vegas, Nevada.

How should DEF be stored?

We recommend storing DEF in our Micro-Matic Closed Containers in a cool, dry, well-ventilated area away from direct sunlight. The ideal storage temperatures are between 12°F and 86°F (-11°C to 30°C).
