DEF Low Message

I agree with stbentoak. I do exactly the same--wait for the on-dash message that DEF is low, fill it with 2.5 gal of walmart DEF. That is not enough to fill it (so no worry of OVER filling it), and rock on for months, til the message appears again. I believe the message comes on when you are within 1500 miles of running out of DEF.
