My 2014 Chevy used to show a warning something like “DEF level low 989 miles”...I don’t remember exactly but it was always in the 900 mile warning. The new Chevy pops up in the 400 to 500 mile range. For the 2014 I remember the dealer told me to add a 2.5 gal jug...I took that to mean “only one jug”.For the 2019 same dealership said I could add 2 jugs (5gals) each time the warning goes off. Chevy does not have a gauge -it’s either ok or it needs DEF.
