Normal is about 7500 miles or so. I would bet that you’ll see it start to show % here shortly (unless your dealer has been topping you off during your visits, if you had visits)
A scan tool can show your usage. I think my usage was something like 1.6grams/km or something small like that last time I checked.
FYI you can’t fit two 2.5gal jugs in even if you let t get down to 10%. I put in one 2.5gal jug in when it shows 30%
