ACDelco DEF Fluid 1 gal (10-4022) — Diesel NOx Reduction for SCR Systems

ACDelco Diesel Exhaust Fluid (DEF) is a purpose-built, aldehyde-free solution designed for diesel engines with Selective Catalytic Reduction (SCR) systems. This colorless, stable liquid aids the exhaust treatment process by converting NOx emissions into harmless nitrogen and water. The product is a blend of high-purity synthetic urea and deionized water, delivering a reliable, ready-to-use fluid for everyday driving and longer trips alike.

Why choose this DEF fluid

The formulation aligns with stringent industry standards, offering peace of mind for maintenance intervals and service checks. It is non-flammable and non-toxic, simplifying storage and handling when following standard safety practices. It also adheres to recognized purity and concentration benchmarks to support consistent performance across compatible SCR systems.

  • Meets GM Original Equipment specifications for GM vehicles with SCR and many non-GM diesel engines
  • High-purity urea paired with deionized water ensures a stable solution
  • Complies with API regulations and ISO 22241 standards for purity and concentration
  • Nozzles sold separately for flexible maintenance and refilling options

Real-world usage and scenarios

Whether you’re commuting, running errands, or taking a road trip, this DEF fluid is designed to support the emissions-control system as intended. The product’s colorless, odor-neutral profile helps reduce concerns about storage and handling in typical home or garage environments. Note that results depend on driving conditions, temperature, and overall vehicle condition.

  • 1 gallon bottle provides ample supply for regular top-offs and routine maintenance
  • Clear, colorless liquid simplifies refilling and supports SCR system integrity

Storage and handling tips

Keep the container sealed when not in use and store upright in a cool, dry place away from direct sunlight. Use clean equipment for refilling to minimize contamination and preserve DEF quality over time.
