DEF Frequently Asked Questions (FAQs)

What is Diesel Exhaust Fluid (DEF)?

Diesel Exhaust Fluid (DEF) is a 32.5% solution of high-purity urea in demineralized water used with SCR systems to reduce nitrogen oxide (NOx) emissions in diesel vehicle exhaust. DEF is a clear, non-hazardous liquid that doesn’t affect diesel fuel and must be filled into a separate DEF tank on your diesel vehicle. If spilled on your hands, simply wash it off with water.

S.A. White offers DEF for bulk delivery directly to your location, or in 2.5-gallon bottles, 55-gallon drums, and 330-gallon IBC totes, which can be delivered or picked up at our Marietta facility. Please call us at 770-427-1387 to arrange delivery today

On average, DEF consumption is approximately 3% of diesel fuel usage, meaning you’ll require significantly less DEF than diesel. For example, 2.5 gallons of DEF can provide over 350 miles of travel when used with SCR technology.

DEF needs to be stored away from extreme temperatures to maintain its integrity. With a freezing point of 12°F (-11°C), DEF will retain its quality when thawed, and vehicles will remain operational during this process. Always store DEF in a sealed container in a well-ventilated area.

DEF purity is critical. Contamination can harm your SCR catalyst and lead to costly repairs. Always use dedicated DEF tanks and dispensing equipment. (DEF purchased from S.A. White remains certified to meet ISO 22241 standards, ensuring the quality required for your SCR system.)
