Hi All,
Update on my new Eco-Diesel (2015 Grand Cherokee 4X4)
Love the car/truck. Getting 32 MPG between Ft. Lauderdale and Miami everyday. (28 miles, mostly highway)
Drove to Virginia, lots of hills, averaged 27MPG. Also, pulled two wheeled Army trailer with 4,600 pounds of water tanks up a gravel hill with EASE!!!!
Happy about that.
Question, will soon be time to add DEF juice.....MOPAR is very expensive. Advance Auto sells it much cheaper (Peak Brand) but someone posted a real problem using it.....(2014 Diesel Jeep, check eng light, incompatible DEF....had to drain clean tank) Next value seems to be NAPA selling VALVOLINE Brand....
Anyone have DEF experience here?
Looking for
INPUT....
Thanks

Stick the MOPAR fluid, it's just safer and won't cause any voided warranty crap if the dealer ever goes down that road. Don't buy mass quantities of it either, it starts to break down after about 60 days. Keep it in a cool dry place and out of sunlight. Do not taunt the fluid, it will hold a grudge and retaliate when you least expect it.

Yeah i would stick to the mopar brand,Like said running the wrong kind can cause a lot of problems.Its cheaper in the long run to use the good stuff.
