From the brand

Product 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.

    Spraying this on my yard and it works well!
    I'm trying an annual ryegrass this winter season and had heard that a liquid application of nitrogen could get me faster results. I've been mixing the DEF at 16 fl oz(2 cups) per gallon, per 1,000 sq foot of lawn I plan to spray. When I get done spraying an area, I'll try to get water on it as quickly as possible. I've done some leveling in the picture and am hoping my edges fill in soon.

    Peak is similar to Prestone in the quality of their products. I was able to receive this product much faster than the product I had purchased before for my diesel engine pricewise. It was three times cheaper and the quality of the product is no different than what I had purchased before through another brand.

    I was always running low, always forgetting to pick more DEF up. Twice I had to pay over double at a fuel station for this. I order 3 to 4 at a time. It’s the real deal at a great price and I don’t have to go out and get it.

    Some have said this is like reviewing water, but really it is like reviewing pee. Good grief if my dad would have told me that we would be paying $5.6 for a gallon of pee, I would have sent him off to the crazy farm.

    Now, I'm a Nurse, so please get the JOKE. o.0
    Okay for real now...

    This works in the new 3.0 Eco diesels which takes in the Jeep and Ram 1500. It works like it is supposed to work. The price however has gone from 11.6 to 13.99 in just a few months. Come on Amazon what happened to lowering the price with more sold? And that is the reason for 4 stars.

    Before the update a few months back my jeep was drinking this like water,I know that sounds nasty from what I said above but live with it, during a few hot days. It also will use a lot while using Chevron's fuel. It might be because Chevron uses clean low sulfur fuel, but this and every other diesel engine in use from 2007 uses ultra low sulfur. I just figured this out and hope it fixes the excess use of the DEF.

    I noticed while driving over 2000 miles in a week that it used less DEF then my Jeep until I put a few tanks of the Chevron. Thats when the gage started to drop like the stock market in my Ram 1500. Maybe I'll update this review after another 2 grand of the cleaner fuel.

    To close this out Blue DEF has the best price. I looked for DEF pumps at the truck stops but they were not around the car pumps. Going back around the big rigs was a little intimidating, and I'm not sure the nozzle would have fit. I know the larger diesel nozzle works on my truck but not the jeep. I'm not sure about the def other then they are the same size on the Ram and Jeep.

    This comes with a little tube coming out of the box that makes is easy to use. No need for the special extra blue funnel. Once my car starting saying I needed to add DEF, we were able to add about 1.5 of these boxes of fluid into the car to fill it completely.

    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!
