What kinda DEF fluid are you guys using? i havent had to fill it yet but just wondering. Salesman told me to fill it when it gets down to half first time then I can just fill it whenever.
I use Peak, from whoever has it when I need it. Usually thats Walmart. You need to be careful ,and not get an old box from someone, DEF does age out. Personally I wouldn't buy any thats over six months old. Walmart usually has it thats a month or less. Peak has a date code that you have to know how to read.
Here is a date code from Peak, from early 2017 that I purchased " GA18297075" Heres how to read it
GA = Where it was manufactured
18= The year plus 1 ,so it was manufactured in 2017
297= The days left in the year ,so 365- 297 = 68 days into the year , so manufactured on
March 9, 2017
075= Batch number
