Current MPG on 2025 i6 3.0 s/o models???

[mbarber84]

Just completed a highway trip from my home to Columbus OH and back. All highway with very minimal regional driving on either end of the trip. Fueled up before and after the trip at the same station.

Truck is a 2025 Crew Cab 6’4” bed
Big Horn Level 2 all stock
4WD SO engine and 3.92 axle
93 octane fuel
Two occupants and minimal gear
Cruise control set at 70mph
Banks iDash showing about 2,000’ish RPM’s

Highest I saw the EVIC mpg was 25.5
Final EVIC mpg was 25.4
Hand calculated was 23.2

Nice job. I find the "MPG (%ERROR)" is not that big of a difference if my MPG is consistent, i.e. I do all highway driving or all local. I also look at the before and after readings as the fill up may not be consistent with the "pump click" from one fill up to the next.
