Greetings from Idaho.
Question about DEF usage. I installed the GDE tune when my truck was new and had just 350 miles on it. Now at over 60K miles I am adding 2.5gal of DEF while pulling our travel trailer ever 2k - 3k miles driven. Is that normal? Still getting mid 20s when not pulling the TT and mid teens when I am.

Thanks, Craig

I'm using about 2 gals of Blue DEF per thousand miles just driving! This seems high to me but I am new to DEF. I just took delivery of a 1500 3.0DSL. I love it, the mileage is tremendous. The dealer delivered it with a 1/2 tank of DEF I added a 2.5 gal of Blue DEF ISO 22241 drove 1170 miles. So will DEF usage go down as the vehicle breaks in ? Are there settings that can be adjusted?
Thanks

Its a little high. May drop down with more miles. Ask your service tech.
