PRIM00250 Prime Guard Premium Diesel Exhaust Fluid (DEF) | 2.5-Gallon Jug
Keep your modern diesel engine running legally and smoothly with Prime Guard Diesel Exhaust Fluid (DEF). Packaged in a convenient, retail-ready 2.5-gallon jug, this ultra-pure fluid is engineered to meet the strict emission-reduction demands of all modern clean diesel cars, trucks, and SUVs.
Formulated with a precise blend of 32.5% high-purity synthetic urea and 67.5% deionized water, Prime Guard DEF injects directly into your vehicle's Selective Catalytic Reduction (SCR) system. It breaks down harmful nitrous oxide (NOx) emissions into harmless nitrogen and water vapor, protecting the environment while ensuring your truck stays out of engine derate mode.
Key Features
