I purchased 5 gal of Peak Blue DEF from Amazon prime..... It's in my shed and I haven't used any yet. But I'm comfortable enough to proceed and am thinking there is something unique about your situation. How did you fix the problem?
I have tried using peak Blue DEF (purchased at autozone)in my Grand Cherokee and the check engine light comes on saying I am using the wrong DEF. I noticed others on the forum buying the same DEF and was trying to determine if there are others with the same issue. Please let me know what brand you are using and if you have any issues
Thanks
Not sure my situation is unique, that's why I am asking to see if people have used it with no issues. I need data to bring to the dealer to get it fixed. Right now I am getting a message telling me the vehicle will not start in 200 miles. Their solution so far is use the mopar DEF at $11. / gal. compared to $12.50 for 2.5 gal of Peak.
I have been using the same one in my GC since I purchased it in Nov. I had a check engine light come on but when I took it in they just said it needed a software update. Nothing since and I filled it right after I had the check engine light fixed.I have been using this
BLUE DEF Diesel Exhaust Fluid - Walmart.com in my 2013 MERCEDES sprinter and now in my GC. No problems to date.
I put 2 1/2 gal of peak blue DEF in today and took it for a spin..... Seems O.K. So far. But I still had about 2 1/2 gal of original so it's a 50/50 mix.Not sure my situation is unique, that's why I am asking to see if people have used it with no issues.

Thank you for keeping us posted.UPDATE - Last trip to the dealer they found a clogged DEF injector. I brought the box of Peak with me to prove it had the same rating as the Mopar brand. I also talked with a buddy who is a diesel mechanic and he thought it was a clogged injector so it pays to go to the dealer informed. The dealer just wanted to blame the Brand because it wasn't Mopar. Apparently some of the def crystallized. They cleaned the injector and tested the DEF and it passed. Drove the GC home and the light came on again the next day but went off a day later. I checked with a scan tool and the code was secondary exhaust emissions out of tolerance. I did not reset the CE light. I am going to drive it and if the Check Engine light comes back on bring it back to the dealer. Not sure if I got a bad batch of DEF that wasn't stored right or if the GC came from the dealer with crystallization in the tank. It seems every time I add DEF to the tank I trip the CE light. This problem started once I added DEF after the first tank was low. If this continues I think the next step is to drain the DEF tank, clean it out, clean injectors and start fresh. If that is the case I am not sure the dealer will see that as a warranty item and may try to charge me. So far everything has been covered by the warranty.
Thanks everyone for the help, I will keep the thread updated if I trip the CE light again.
that was interesting...bit of a learning curve with this new diesel.
AT the dealer, LOF, oil filter about $40-50, DEF refill will be near $200.00???
