Peak BlueDEF Diesel Exhaust Fluid

Part No. DEF002 Warranty  
Diesel Exhaust Fluid (DEF) is one of the key elements of the Selective Catalytic Reduction (SCR) process used by Diesel Engine builders to meet EPA 2010 regulations. BlueDEF is a nontoxic solution of 67.5% purified water and 32.5% ultra pure automotive grade urea. BlueDEF is not a fuel or fuel additive. Instead, when injected into the exhaust stream and passed over a catalyst, BlueDEF helps convert NOx into nitrogen gas and water vapor - two harmless and natural components of the air we breathe. BlueDEF is stable, colorless and odorless, and meets ISO Standards 22241 for purity and composition and is an American Petroleum Institute (API) certified diesel exhaust fluid. These are the highest quality and safety standards in place to ensure optimum SCR performance. Making sure you do not run out of BlueDEF in a SCR equipped truck is simple - watch the DEF gauge, which is part of the diesel fuel gauge, for when it is time to refill. DEF is stored in a dedicated tank next to the fuel tank on the driver's side. The tanks range in size from 6 to 23 gallons depending on the truck's application. The DEF tank fill opening is designed to accommodate a DEF fill nozzle to ensure only DEF is put into the tank. A diesel fuel nozzle will not fit into the DEF tank opening. Our patented closed liquid dispensing system provides everything you need to effectively dispense your BlueDEF. In order for BlueDEF to work well product integrity is critical and our dispensing systems are the only way to maintain this quality. These reusable systems are also cost effective by providing a significant savings over single-use containers. BlueDEF dispensing systems are available in configurations for fleet, retail and commercial applications. BlueDEF is key to helping improve fuel economy by up to five percent while simultaneously reducing exhaust emissions.

Greater Value vs. Dealer Product

Its better if container is removed from box prior to filling.
Works better if a vent hole is punched in the back of the container.

We had a code pop up related to poor DEF quality after putting this in. We did not have any issues with the factory Jeep DEF fluid nor with the Gumout DEF fluid. This was on a 2014 Diesel Grand Cherokee 3.0. After draining the DEF tank of the Peak brand, clearing the code, and refilling with Gumout brand we did not have any issues. Maybe we received a bad batch. Either way, if you get a check engine light after refilling with the Peak, check the OBDII code and google search and see if it is related to poor DEF quality.

              Have used only peak diesel exhaust fluid since new with no problems.Over 24000 miles on truck, mostly towing 13000 pound trailer and product lasts longer than G.M.C. states average usage. Packaging is convenient size and it comes with a built in pour spout which helps as urea fluid is caustic and will damage paint if spilled under hood so care should be taken when pouring and any spills should be cleaned off immediately. Product is required on all newer diesel trucks and truck will automatically slow down when low on fluid. Peaks product has never given me an issue and is a great value.
