## 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....
