- One gallon of is used approximately every 300 miles
- A truck with a 20 gallon DEF tank can go up to 6000 miles between fill-ups
- When used in an SCR system will reduce the levels of NOx emissions of those engines
- Prime Guard DEF is a safe, environmentally friendly solution for Selective Catalytic Reduction
- Meets GM Original Equipment specifications to be approved for use in GM vehicles as well as in non-GM diesel vehicles that have an SCR (Selective Catalytic Reduction) system to meet regulated NOx emissions (Based on EPA certification testing. Your actual emissions will vary based on several factors including temperature, terrain, and driving conditions).
- High quality formula is made from high purity urea and deionized water.
- Meets API regulations and ISO 22241 standard for purity and concentration
- Nozzles sold separately
- Diesel Exhaust Fluid is sprayed into the diesel exhaust streams of diesel engines to lower the concentration of nitrogen oxide, NOx, in emissions
- Engineered for use in Selective Catalytic Reduction (SCR) systems on diesel engines, BlueDEF diesel exhaust fluid is comprised of a high-purity synthetic urea and deionized water mixture that improves emissions and fuel economy
- When injected into the exhaust stream with a specialized dosing module, BlueDEF's water vaporzies, leaving ammonia molecules en route to the catalytic converter; once there, it converts NOx molecules into harmless nitrogen and water vapor - making for cleaner emissions
- To ensure Selective Catalytic Reduction (SCR) performance, diesel exhaust fluids must adhere to the ISO 22241 standards
- Diesel Exhaust Fluid (DEF) is made with 32.5% urea, (NH2)2CO, and 67.5% deionized water. Diesel Exhaust Fluid (DEF) is non-toxic and safe to handle, but it can corrode some metals, so it must be stored and transported carefully

On certain vehicles, the exhaust pipe outlet (also known as the exhaust pipe mitigator) may have been mis-installed, facing the tip towards battery boxes mounted directly above between the frame rail.
Describe the safety risk:
In some cases, the exhaust heat may melt the battery box and possibly result in a thermal event.
Identify any warning which can precede or occur:
Exhaust can leave residue on surrounding components, melting of surrounding components and/or smell of melted materials.
If applicable, identify the manufacture of the defective or noncompliant component.: N/A
