    Thanks a lot! easypar

    I had my first oil changed 3 months after I purchased this car at 1000 miles which is suggested by Subaru owner's manual. Now it is about 7.5 months and I will do the second oil change next week and see if the MPG can be improved. I will ask the dealer to check the air cleaner too.

    I just don't get it why so many people have such great MPG in both city and highway. As I see, most of them can gain from 23-27 MPG. Now I can only have 16.2, which is too abnormal.

    It is my first outback and everybody told me it is a very reliable car before I bought it. I was very happy with it until last week. I got two recall letters from Subaru America regarding windshield wipe motor and moonroof. Although they are just small problems, I still feel uncomfortable. :sick:

    Keep in mind they are merely addressing even minor issues. That should actually reassure you.

    Subaru had issues with head gaskets and extended warranty coverage on those to 100k miles, too.

    Honestly, it depends on how "city" your city driving is. If it is literal stop/go every quarter mile (or less) all the time, mileage is going to be terrible. There is just no way around that. Typical city driving involves some distances of a mile or more before having to stop again, which then helps to bring that average up.

    If it's cold, mileage will basically stink until the engine is warm. So for the first mile or two you are getting terrible fuel efficiency.

    That's why it's a good idea to combine errands - the engine's already warm.

    Thanks both xwesx and ateixeira!

    Yes, I do have a lot of stop/go on the way to work and back to home in my city. The weather here is nice but I still warm up my car every :blush: morning (until the blue light off) and remind my wife to do so as well. I believe the MPG on highway is much better than the city roads with a lot of traffic lights and stop signs. Anyway, I will keep watching my MPG.

    THAT is what's killing your gas mileage. Modern cars do not need to be "warmed" up before driving off. Start the car and drive "sensible" until it's warm.
  • ateixeiraateixeira Posts: 72,587
    You can drive while it warms up. The ECU is programmed for that, actually, so it's OK to drive off.

    You should give it enough time to establish oil pressure and flow before driving off, but that's a matter of seconds, not minutes.

    This morning I calculate the MPG again by myself between two filled-up. The MPG is 16.2. 50 miles city roads killed 13 litre. The trip computer for the average MPG reset after last filled up is accurate, showing 16.2 MPG.

    I don' think it relates to the warm-up engine issue. It'd never happened before I drove extra 15 miles when the low fuel light was on last week. I think the poor MPG may be the consequence of potential gas pump damage. Is that possible?
  • ateixeiraateixeira Posts: 72,587
    It would be hard to isolate it to one factor, since there are so many.

    Remember, when you're sitting still, idling, you are getting 0 mpg. Enough of that will bring your average down no matter what kind of roads you drive on.

    I have had a similar experience. On my last trip I got 35.7 mpg, mostly interstate driving with 2 adults and luggage. I also have noticed that if I buy my gas in central or southern Virginia, I will get up to 2 mpg better than Maryland gas. I have the same 2010 Outback Ltd with 2.5 ltr.

    We have 33k miles on our 2010 Legacy 2.5i, generally getting 27 to 27.5 MPGs with about 35% City (some suburban , but also Real City - NYC that is) and 65% Highway (NYC Highway- traffic, of course). A little drop off during winter months due to "winter Blends of gas".. More Ethanol. Can't say any big difference since hitting 30K miles on the clock. My 26 year old son uses the car to commute to his job - 60 miles a day (Thank God he has a job), we share the expense (Insurance, loan, gas, - no way could he afford it on his own). So considering he does NOT drive like your Grandma...27 average MPG is pretty good. Last week, I took the car 90 miles round trip with anew fill up, I got 31.5 MPG with mostly highway and some suburban city miles. That's the internal trip computer readings.
  • almattialmatti Posts: 164
    I also find that every now and then I'll put Mid Grade or Premium - 10 or more gallons, I do see a slight increase in the MPGs - maybe .5 / gallon. With the price difference in the grades of gas, it's NOT worth it. But I'm Old School....a tank of Hi Test is like Brile Cream: A Little Dab'll Do Ya.

    My 2011 OB2.5 CVT just passed 10K in OD reading so that it's fully broken in now. With the warm weather last Saturday, I thought it's good chance to know what is the optimal MPG this car can do when we went to LA from San Diego.

    I filled up before and after the trip. Set cruise at 65 (I know it's slow:); about 20% of the time was 20-40 mph because of slow traffic. The total trip was 237 miles and gas used was 6.56G. I knew the CVT is good, but the whopping 36.13MPG (by hands, 35.7 by trip computer) was unexpected.

    My life time MPG for the OB is about 29(by hands) vs 30(by trip computer).

    For what it's worth I recently took my 2.5i Outback Limited (CVT) on about a 500 mile trip each way from NJ to the Outer Banks, NC. The trip computer said we hit just over 40.0 MPG for the tank when I filled up after driving 9 hours straight, through the night, speed was probably an average of around 55 MPH, very few "red" lights. I think we have just about 25k miles on the Outback now. Used cruise control for 95% of the trip.

    I cross-checked it the next day when I filled up my gas tank and the numbers checked out for the amount that was pumped into the partially-filled tank. Couldn't believe it.

    My wife and I just completed a 5000 mile vacation, using our 2.5i Outback. (CVT) On any of our previous trips, the best mileage we ever got was 27 +-. Usually 900 mile jaunts up to Seattle from Reno, Nevada, and back..all steady 70 mph, cruise control driving, on the I-5 Interstate.

    This time, we went to Portland Oregon, then to Seattle, then to Blaine, Washington, where we crossed into Canada, to a ferry over to Vancouver Island, a ferry back to Vancouver, then cross country up to Banff and to Calgary and Edmonton, then down to Saskatoon and Regina, and finally Winnipeg, then down to and home via I-70 and I-80. Unbelievably, our over all trip mileage was 29.95 MPG. Not the 30 - 35 you folks are getting, but I am not complaining...the $1.44+ a liter (about $5.30-$5.45 a gallon) in Canada was a bit unexpected. With the exchange rate, that was really about $5.10 US, a gallon. The car had 31k when we started the trip...now has almost 37k.

    Everyone has said the engine has to get really broken in to get the good mileage..perhaps, if true, it took longer on our Outback because we use only full synthetic oil..Something to contemplate.

    How loaded were you on that trip, MC? Given the areas you traveled (and likely the speeds), ~30 mpg is pretty good! Pilot really hit the sweet spot with that run to the outer banks, as the slower speeds, minimal traffic, cooler temps (possibly even no A/C?), and steady running really combined to make for some great mileage.

    Thanks for the info on current fuel prices in Canada. We'll be headed through there in a few weeks, and were planning to go from Fairbanks to Montreal entirely through Canada (e.g., crossing the continent), so it's nice to have a solid idea of what to expect as far as fuel prices go! Realistically, we're probably looking at ~27 in our Forester (2010, 5-speed).

    Have had car only 2 months but have almost 7k miles. 3 trips Chicago Cleveland and one Chicago Boston. Averaging just over 30mpg calculated on interstate cruising at 70. On state highways in the Adirondacks going up and down hills even at slower speeds dropped to 27. CVT seems to make the engine accelerate a lot on inclines in cruise control mode.

    We were loaded to the hilt...we had my mobility scooter in the back (and a trailer I pull behind it), plus a big *full* ice-chest, as well as my camera bag (Humongous..3 Nikons, and 12 lenses plus batteries, filters, and memory cards.) plus all our clothes and toiletries.

    We inflated the tires to the maximum, so the ride was a bit hard, but not bad, considering

    And you hit 30 mpg! Color me jealous.... :-P

    Rereading my last post, I realize it sounds like I pull a trailer behind the Outback. No, the trailer I pull behind my mobility scooter. The wheels come off and the trailer folds flat for storage/transport.

    We took 3 hour trip driving our 2013 Outback 2.5 a few times to the coast. The displayed reading was 34.5 and 34.6 MPG respectively. I fill up wit 87 octane. The MPG seems pretty high. Could this be accurate? If it is it is pretty incredible for a vehicle of this size.

    I find that Subaru's economy calculators are a little bit optimistic averaged over time, but mine have only been off by 1 mpg. So, if that holds true for yours, you're still getting 33.5, which, I agree, is pretty incredible for a vehicle of this size! *insert thumb's up emotorcon, if there was one, here!*

    Purchased a 2013 OB October 2012. Have about 8500 miles on it. No issues whatsoever. Changed the air filter from stock to a K&N replacement. Mileage went up about 1.5 miles per gallon. I drive 60% highway the rest city. The K&N also improved throttle response to boot.

    Did one long trip to NYC from D.C. early in the life of the car (about 1500 miles). Got about 28 MPG for the trip.

    Have a long trip to Florida coming up in early December. The Subaru will be making that trip. I will let you know how it does.

    If your onboard MPG calculator is inaccurate... all you have to do is adjust its accuracy. Subaru has provided a way for the accuracy to be compensated by pushing some buttons on the dashboard. The outside temp meter can also be compensated.

    The quickie guide to do this is below:
    =============
    Go fast...ignition on
    turn headlights on
    hit trip meter 5 times
    headlights off
    hit trip meter 5 times
    headlights on
    hit trip meter 5 times

    Now you can adjust the MPG reading on the first option screen. Default is zero

    "Go fast, ignition on???

    HUH? In order to go fast, you have to have the ignition on. LOL.

    Care to restate how to calibrate? Yeah..our actual mpg mileage is no where near what the dash indicator states......the mpg averager in my Corvette is rarely off by more than a tenth of a gallon. (Believe it or not, I get better mileage (actual) in my Corvette [31-32 mpg, at 75 to 85 mph], than we do in our Outback. Go figger.)

    I will try to be more specific... to compensate the accuracy of your MPG meter and other display on Subaru... you need to put the system into "DEALER CUSTOMIZE MODE" To enter this special mode you need to manipulate the ignition-switch, headlight-switch, and trip-meter button (LEFT hand button on dash)

    The items you can adjust are
    *) MPG (percent adjustment)
    *) Ambient Temperature (degree adjustment)
    *) Clock-speed

    The "Go Fast" means that you have about 10 seconds to complete the entire process of entering "DEALER CUSTOMIZE MODE". Also the "ignition switch on" does NOT mean to start the engine!

    Perhaps this website will help guide you ==> http://www.subaruoutback.org/forums/104-gen-4-2010-present/36268-dealer-customiz- e-mode-how-adjust-fuel-economy-display.html

    Just approaching 50K on my 2010 2.5/CVT Outback and consistently get 34+ MPG on freeways doing 72-74 on Michelins.

    I have a 2013 2.5i Outback Premium purchased nearly two years ago. Has 25.4K on it and it runs well. Recently took a trip to Florida and averaged about 28 MPG. Best fuel economy was 30.1 M PG on on leg using 90 octane 100% gasoline. (no ethanol). CVT works well but the driving technique requires a light right foot to get it to respond the way you want it to. The paddle shifters are helpful under certain conditions. Got rid of the OEM Continentals. Running Pirelli P7 Cinturato tires. Car rides more quietly and more smoothly. Handles much better too.

    Still miss the torque from my Jeep Liberty CRD. The Outback could use another forty lb-ft of torque.
