my gauge reads 24.6 constantly, no matter the speed. Its gone to 24.7 once before, I think. Also, when I push trip to mph, it says somewhere in the 30s, constantly. How do I get my gauge to read more accurately? Didnt mean to hijack the thread

For it to read more accurately, you need to reprogram the ECU....and I mean actually reprogram the firmware in the ECU that grabs all the sensor inputs & aggregates it into the readings you get. But I'm sure Nissan made it as close to accurate as they could get it, given the circumstances.

But reset the trip and you might think it's more accurate 'cause then it's only in the short-term.

Over 80 MPH, mileage drops to 23. If I stay around 70, mileage rises to 28 or 29. City driving always around 21 or 22. My right foot seems to decide my mileage...
