Gas mileage by rallyfan

I just bought a 08 SE Legacy 2.5 auto. and I am getting 23 miles to the gallon combined. I live in a rural area not a big city. It only has 2k miles on it and I am taking it easy so it will break in nicely.

Just pulled 24mpg over a 1,000 mile trip including city, high speed highway, lots of idling, and some offroading. Not too shaby in my book.

1997 Outback Ltd automatic - 23 lifetime by steve_ HOST

I picked up my Outback used from a friend in March, '03. It had 34,513 on the odometer when I first filled it up. My lifetime mpg today, at 67,564 miles, is 23.08.
 
I've had three tanks over 30 mpg, and three under 15 mpg, so I figure all of those are aberrations that cancel each other out.
 
I can see a slight trend for better mpg in the winter, likely because it has a black leather interior and 105°F isn't all that unusual here in Boise in high summer.
 
Most of those miles are interurban, and I'm a pretty relaxed driver usually, at least pulling away from the light.

We just picked up our 08' Legacy Sedan SE this Thurs and are thrilled with it thus far! Our first tank of gas yielded 23.7 mpg on mixed city/highway driving - most of what I would call "suburban" driving.

Congrats.
 
Mileage should improve as it breaks in.

First fill up on my 09 Legacy SE yielded 23.5 with 50-50 city/highway mix. The trip computer registered 26.1 for the same period.
 
It's early and I expect improvement down the road but I'm wondering if the trip computer is generally this overly optimistic or there might be some other factor involved.

We just bought an 09 Legacy w/std 2.5 engine. Our readout seems about .5 mpg high when I compare it to fill-ups (only a few, thus far...) which seems to be about where most posts (on various forums) that I've seen regarding this matter have been....usually between .5 and 1. Your 2.6 difference seems a little high in comparison to what I have read thus far. I bet it'll be better on fill-up #2.

You can't judge by the first fill-up. You don't know exactly how full the tank was when you picked up the car. Reset the trip meter and take an average of the next three fill-ups and compare to the computer. It should be fairly close, within 1 MPG.

Just purchased a 97 outback cause i thought it ran really well.
Have filled it up three times now, and have calculated that I am averaging only 12.5 to 13 litres per 100k (that's 18.1 to 18.7 miles per gallon). Seems oftly low, especially when moving from my 87 Camry that was yielding me 29 miles to the gallon, even now at 22 years old).
 
Anyone suffer poor mileage on these? I know they're all-wheel drive, which consumes more, but this seems lower than normal. Will a full tune-up help? The tires are properly inflated.
 
Thanks,

Tune up will certainly help in many cases...new plugs, wires, air filter, and a new fuel filter just upped my '98 from 19 to 23 overall...
