Prime Guard Ultrapure Diesel Exhaust Fluid is a critical solution for owners of modern diesel vehicles equipped with Selective Catalytic Reduction (SCR) systems. You will find that this high-purity fluid is essential for converting harmful nitrogen oxide emissions into harmless nitrogen and water vapor, ensuring your truck or SUV remains compliant with environmental standards. Using a premium, ultrapure fluid like Prime Guard helps protect the delicate and expensive components of your exhaust system from the buildup of mineral deposits that can lead to costly repairs and engine “limp mode” warnings. This 2.5-gallon jug provides a convenient amount for a significant top-off, allowing you to maintain peak performance during long-distance hauls or daily work routines.
Key Features of Prime Guard Ultrapure Diesel Exhaust Fluid
Additional Information
When refilling your DEF tank, always look for the dedicated blue cap, which is usually located next to your diesel fuel filler or under the hood; never mix this fluid directly with diesel fuel, as it can cause catastrophic engine damage. It is a good practice to wipe the area around the fill port before opening the cap to prevent dust or debris from falling into the reservoir, as even small contaminants can clog the system’s fine filters. Because DEF has a shelf life that can be shortened by heat, store any remaining fluid in a cool, dry place out of direct sunlight to maintain its effectiveness. If you happen to spill any fluid on your vehicle’s paint, simply rinse it off with water immediately to prevent white crystalline residue from forming as it dries.
