105,850 miles since I bought the car at 3 miles. Never gotten a better average than 32. Typically at 29.7. Mixed driving. Lose about 2mpg when the roof rack is on.

Sounds about right although I tend to stay 28mpg or so because of the idiot drivers and piss poor traffic light timing around here.

Just reset my mpg, I do it whenever I change the oil, and in the first 190 miles on my daily commute my average mpg is at 34.5 which includes a little city driving.

Default MFD average mpg display vs real-world display

Hello all, I'm new to the forum. I have a 2013 Impreza Sport since June. I have been keeping track with all of my fill-up. Average 28-29 combined. Getting into winter in CO it's taking a dip but it's expected since I have to warm up longer. However, I have been noticing that the MFD avg mpg is consistently higher than my record by 2 mpg (I tried to be consistent with all of my fill-up, almost full tank, no excess pumping, trip mileage and avg mpg is reset after every fill-up). I bought this car used so I don't know if the prev owner changed the MFD or not. Is this a common problem and is there anyway to fix it? screenshot: https://flic.kr/p/2hA7x3z

Only adjustable by a dealer, +\- 6, i had mine done when new so it didnít cost anything

Your odometer is probably off by 3% too....

i can corroborate both your experience as well as Flyboy's:

on average, the computer is over predicting by about 2 mpg overall. but a the same time, the odometer on my 2012 is off by about 3%. so in the end, i mentally note that what shows up on the computer is about 1 mpg too high.

Thread revival!

'12 Impreza "Sport", 130k, 5spd manual (New longblock at 103k)
(Edit: Probably should mention the ~150 lb. of tools, etc chilling in the hatch. I should leave them since the car is plenty reliable, but I just can't. I like being able to help out when I see someone sitting hood up, face in palm.)

Condition 1: Best. Avg mpg: 30.1 calculated (32.1 dash)
That was a 1am drive from Richmond VA to Rodanthe NC and back. Sadly I didn't record the avg speed. I generally run 9mph over in anything over 35mph, and nobody was on the road. Pretty ideal conditions for good mileage (well, aside from my tools and my +9mph habits).

Condition 2: High speed interstate. Avg mpg: 25.7 (27.3)
I81 Staunton to Blacksburg and back, moderate traffic, somewhat heavy on the gas when needed to get around trucks and idiots. Probably 25 miles of city driving mixed in.

Condition 3: Heavy traffic interstate. Avg mpg: 24.5 (27.3)
Same as 2, but one way (Staunton -> Bburg) with heavy traffic with mixed in stop and go, and ~40miles city.

Condition 4: Worst case. Avg mpg: 21.7
Mostly city, heavy pedal (was testing oil consumption vs driving style.)
Ummm...this is embarrassing, I can't find this one in my notes, so I don't remember what the dash reading was. I'd rather not do this test again either, oil consumption more than doubled vs feather pedal.
