There is no way I would pay what they want for Mopar DEF. Its all the same. I have been using the brand that is sold at Tractor Supply called Terra Cair in my ram and haven't ever had an issue. It's 8 bucks for 2.5 gallons.
Yes I fell into that trap when picking up my new Ram! I get it now at wally world in the 2.5 gal containers.
