Please stop posting DEF per milage, it's confusing, all that matters is DEF per fuel burned. Should be 2-5% of fuel used. Don't use the gauge to factor how much DEF you have used its not accurate. FillIing your DEF tank is the only way to know how much DEF you've used.
Tell us something most of us didn't know....I would say most will figure however they want to figure..I fill up my DEF tank to a set point...re-set mileage...next time I fill up, I divide mileage by how many gallons of DEF I refill to..Never knew or heard of a rule that states you can't or shouldn't do it that way:h..Don't know what is confusing about it for those of us that know how to do the basic math skills and state how many miles per gallon of DEF we got..
Most also know that the gauge is useless, it's non-linear, it tells you nothing...again, most know that...It'll show full for a long, long time...then start dropping out of nowhere...maybe those who have never had a DEF truck don't know that...but it was discussed well ahead of all this.
THUS, the reason I stated....I fill to the same spot each time....when pump clicks off...been pretty doggone accurate over the last 28,000 miles.
