## Overview

Blue Def DEF002-2PK Diesel Exhaust Fluid is a high-purity, EPA-certified solution designed for SCR-equipped diesel engines. Each 2.5-gallon jug supports up to 300 miles of driving, with a 20-gallon tank enabling up to 6000 miles between refills. This non-toxic blend of purified water and automotive-grade urea reduces NOx emissions, helping trucks meet stringent environmental regulations while maintaining engine efficiency. Packaged for easy use and trusted by professionals, Blue DEF is the essential fluid for modern diesel performance and sustainability.

## Description

Diesel exhaust fluid is one of the key elements of the Selective Catalytic Reduction (SCR) process used by most medium and heavy-duty engine builders to meet EPA 2010 regulations. Blue DEF is a non-toxic solution of 67.5 percent purified water and 32.5 percent ultra pure automotive grade urea. Blue DEF is not a fuel or fuel additive. Instead, when injected into the exhaust stream and passed over a catalyst, helps convert NOx into nitrogen gas and water vapour, two harmless and natural components of the air. is stable, colourless and odourless, 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 in a SCR equipped truck is simple, watch the Diesel Exhaust Fluid (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.

Review: They made it right right away. - Seller addressed a simple mistake ASAP & made it right, they went over & above. As for the product itself, the price was right & Blue DEF is all we will use in our diesel engine camper van.
Review: The best synthetic cow pee for your modern diesel truck - I order this stuff online because I don't like interacting with weird people. I don't know if it's cheaper in stores or not, I don't really care. To not have to talk to someone at the gas station or auto parts store is worth it to me. Of all the synthesized cow piss on the market for trucks that require DEF, this seems to be the creme de la creme, squoze from only the finest pure bred Holstein heifers and mixed with mountain spring water. I have used this brand for 5 years and while I have no idea if it actually does anything other than make my truck's exhaust smell horrible, it hasn't ever created any mechanical issues with the truck. I ordered the two pack and received two, 2.5 gallon jugs, as advertised. The spout that is included sure makes refilling the tank easy, and then I throw that away with the jug that the DEF comes in, which is inside of a cardboard box, inside the desertcart box. Somehow DEF makes the environment better, I don't get it. But I'm apparently not as smart as the folks at the EPA. I mean, who figured out that a mixture of water and urine extract, injected into an exhaust and then processed through and SCT and/or DPF would save the Earth from some unburnt fuel? Remarkable foresight. Yay for government!

## Features

- One gallon of is used approximately every 300 miles
- A truck with a 20 gallon DEF tank can go up to 6000 miles between fill-ups
- When used in an SCR system will reduce the levels of NOx emissions of those engines

## 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....
