BlueDEF Diesel Exhaust Fluid in a 2.5-gallon box is designed for diesel vehicles equipped with SCR systems. This fluid helps enhance fuel economy while producing cleaner emissions. By adding BlueDEF to your exhaust stream, you effectively reduce harmful nitrogen oxide emissions. The fluid works by converting NOx into harmless nitrogen gas and water vapor, making it an eco-friendly choice. It is a non-flammable solution made from a precise mixture of urea and deionized water, ensuring it is completely water-soluble, stable, colorless, and odorless.

The 2.5-gallon jug offers a convenient storage option for when you're on the go, allowing you to keep it in your trunk for easy access when your levels run low. Applying the fluid is straightforward—just inject it into your exhaust system when needed. BlueDEF is approved for use in all diesel SCR systems, making it a reliable and versatile choice that can boost your fuel economy by up to 5 percent. It’s important to remember that BlueDEF is not designed for use in the diesel fuel tank. With BlueDEF Diesel Exhaust Fluid, you can contribute to a greener planet while also saving money at the pump.
