Composed of 67.5% deionized water and 32.5% synthetic urea, it meets ISO 22241 purity standards and helps reduce NOx emissions while improving fuel economy by up to 5%. Non-toxic and easy to handle, BlueDEF offers a cost-effective, eco-conscious way to maintain EPA 2010 compliance and keep your diesel engine running efficiently. ## Description 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. Diesel Exhaust Fluid is a nontoxic solution of 67.5% purified water and 32.5% ultra pure automotive grade urea. Diesel Exhaust Fluid is not a fuel or fuel additive. Instead, when injected into the exhaust stream and passed over a catalyst, Diesel Exhaust Fluid helps convert NOx into nitrogen gas and water vapor – two harmless and natural components of the air we breathe. Review: Good stuff - 100% stand by this stuff. Cheep brand shows codes in my dpf. Review: A LOT cheaper than getting a garage to do it - At the price I paid for it, it's MUCH cheaper than the last time I paid a garage $70, basically the same price as an oil change. I also bought a funnel and I can pour it into the tank in the trunk. It's better to have 2 people to do it; one person to hold the funnel and another to pour. I'm not sure when it's getting close to the top but I can add more at my convenience. I probably saved about $50 by not going to the garage! ## Features - ENGINEERED: For use in Selective Catalytic Reduction (SCR) systems on diesel engines - EFFICIENCY: BlueDEF diesel exhaust fluid is key to helping improve fuel economy by up to five percent - PROTECTION: Diesel exhaust fluid is non-toxic and safe to handle - QUALITY: Stable, colorless and odorless, and also meets ISO Standards 22241 for purity and composition - EFFORTLESS: Easily Inject the fluid into your exhaust stream with a specialized dosing module ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004O80QP8 | | Best Sellers Rank | #165,341 in Automotive ( See Top 100 in Automotive ) #6 in Heavy Duty Vehicle Antifreeze, Coolant & Diesel Exhaust Fluid | | Brand | BlueDEF | | Brand Name | BlueDEF | | Capacity | 2.5 Gallons | | Color | Blue | | Customer Reviews | 4.7 out of 5 stars 731 Reviews | | Fuel Type | Diesel | | Global Trade Identification Number | 00074804032116 | | Included Components | Spray | | Item Dimensions W x H | 9.5"W x 9.5"H | | Item Type Name | BlueDEF Diesel Exhaust Fluid Synthetic Urea & Deionized Water 2.5 Gallon Jug | | Item Weight | 24 Pounds | | Manufacturer | BlueDEF | | Material | High Density Polyethylene (HDPE) | | Model Number | DEF002 | | Part Number | DEF002 | | Product Dimensions | 9.5"W x 9.5"H | | UPC | 074804032116 | | Unit Count | 1.0 Count | | Warranty Description | Manufacturer Warranty | ## Product Details - **Brand:** BlueDEF - **Color:** Blue - **Item Weight:** 24 Pounds - **Material:** High Density Polyethylene (HDPE) - **Product Dimensions:** 9.5"W x 9.5"H ## Images ![BlueDEF Diesel Exhaust Fluid Synthetic Urea & Deionized Water 2.5 Gallon Jug - Image 1](https://m.media-amazon.com/images/I/71luyImitXL.jpg) ![BlueDEF Diesel Exhaust Fluid Synthetic Urea & Deionized Water 2.5 Gallon Jug - Image 2](https://m.media-amazon.com/images/I/613qtHIrJzL.jpg) ![BlueDEF Diesel Exhaust Fluid Synthetic Urea & Deionized Water 2.5 Gallon Jug - Image 3](https://m.media-amazon.com/images/I/61g5Og4aEjL.jpg) ![BlueDEF Diesel Exhaust Fluid Synthetic Urea & Deionized Water 2.5 Gallon Jug - Image 4](https://m.media-amazon.com/images/I/71zFyaTfzWL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What Is It Made Of?** A: Fairy Tears, Tree Sap, Frog Saliva and Mosquito Urine. **Q: Sorry, still confused. Am I getting 2.5 gallons or 5 gallons?** A: 5 Gallons. It is 2 bottles, each bottle is 2.5 gallons each. **Q: Your description says a two pack. That means two 2.5 gallon containers. I see your reviews say false adverstisment, so which is it? One or two pack?** A: I don’t recall saying anything about false advertisement. I received 2 containers of DEF that were 2 1/2 gallons each. A total of 5 gallons. **Q: Will this work in a 2014 Grand Cherokee diesel without setting off the "Improper DEF" warning? This product is much cheaper than buying the MOPAR version. Thank you.** A: 1. the Peak Blue Def is what I use in my 2016 Ram 1500 ecodiesel, DO NOT buy it online, you can buy it cheaper on the street... Farm and Ranch stores is much cheaper as in 8 or $9 a 2.5 gal jug... your def tank if it's on a truck should be about 10gal, to answer your question, when can you add it, you can do it at anytime... when your def tank is about 1/2 full or empty, just pour in about 2 jugs, which equals 5 gals... but, that second jug, add slowly especially when you get towards the last 1/4 of the jug, otherwise, the overfill splash gets kind of messy, and def, it'll crystalize on all other surfaces... so keep it in the jug or in the def tank... another note of interest, someone on this thread mentioned that you can pick up def fluid at some truck stops... I have heard pro's and cons about that... the pro's, if they are charging 2.40 a gal that's cheap, but, those truck stop def fluid fills do not tell you what the specification their fluid meets... so, attain the approved specs from your owners manual, the Peak blue def product meets mopar spec standards.... ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good stuff *by B***Y on June 19, 2026* 100% stand by this stuff.
