Did you had a similar average like mine’s on the first tank ?I have mine to reset Trip A after a fuel up. I also have Trip B reset on ignition.
Yesterday, I was able to get 25.6 mpg (Trip B) with mixed city and highway driving. No Econ and Auto Start/Stop disabled. Normal driving for me, didn't really punch it or drive too slow. I'm at 800 miles, 2021 Black Edition.
Well here is the thing , it has never changed since I drove it out of the lot with 5 miles on it , i just started my second tank and it’s still showing at 15 mpgFirst tank is completely valueless as a barometer of mpg. Any cars instant mpg reading will scare the dickens out if you from a cold start, full ac etc for at least the firsr few miles.
I’m constantly amazed on any car in the family fleet how the range changes as you drive.
