    yes, I use 93 octane, and I keep the tires at 35psi.

    You won't do as well but keep in mind the interior is about 5 times as big. ;)

    True true, the mini is long gone, after 6k in repairs, i had enough.

    I drove the nonTurbo, just waiting on a turbo to come in to test drive.
  • jrock56jrock56 Posts: 5
    bit the bullet and LOVIN IT!!!!

    Got an 09 XT, i wanted the turbo for the extra power, i scored a deal on a demo, so I am happy with it, plus i felt that the nonturbo was just too sluggish when passing.

    Averaging 21mpg with mainly city driving at this point.

    Been two weeks now, have approx 1800 miles. Mostly highway driving, but a fair amount of "rural" 50 mph stuff with few stops. Based on actual consumption, averaging 23.3, trip computer one of which I have not reset for same perior indicates 24.3, I believe. I am a little disappointed that I am not getting any better, although I realize vehicle not broken in yet. Heck, on my 06 Tribeca that I put on 65k, miles, I was averaging approx 20.5 for same type of driving. Sure hope this improves.

    Was hoping to run into snow, I really wanted to try this out. Have been all around upstate NY last few days, Plattsburg over to Massena, now back down in Lake Placid tonight. Saw a few patches of snow on the sides of the road, but not enough to driver over.

    Oh well, may have to wait until next year.

    For those out there interested in "real world mileage" I have read so many posts on this an other boards claiming unrealisticall high mpg on this vehicle (like over 30) as well as some extremely low. I will be a frequent poster on this board (maybe I like reading my own posts) but all of you can be assured when I give mpg figures they are not pullled out of a hat, or based on what the trip computer says over a stretch going 50 mph on a rural road (which will be quite inflated.

    For the first three weeks, mileage per trip computer 24.6. Actual mileage based on actual gas usage was 24.1. It was actually 23.9 but I know when I got the vehicle from the dealer although "filled" it was not "to the brim" and probably was at least a gallon short of being full.

    That being said, pretty close, only .5 miles difference. On my trip today, Providence RI out near Brattleboro, VT and return mpg per trip computer was 26.4, and actual was 26. Did much better on second half coming home as I was mostly on turnpike going out, but more "rural roads" coming home.

    Kind of hoping as this vehicle gets broken in rthe mpg will improve. Also, warmer weather will help a bit as well. I would have loved to have the "turbo" but I know the mpg would suffer, probably average low twenties, plus premium fuel. I am surprised how few turbos dealers even have in stock. Over 30 Foresters at the dealer I bought from but just one Turbo (that seems to be sitting with no takers)

    Will keep the board posted as I increase mileage. I think another 500+ mile trip coming up on Thursday.

    occking, I own a 2009 Forester XT and I was able to get 26mpg on a trip from Baltimore to Providence, cruise control for as much of the trip as possible (very tough to do on 95 through the Northeast) and doing 65-70mph. This was not a computer display number, this was my actual calculation from fill up to fill up + trip mileage. If I can do 26mpgs in a turbo then I completely believe that people who have posted 30mpg in their NA Forester are telling the truth and were able to get that result.
  • occkingoccking Posts: 346
    That's great to get that kind of mileage in a turbo! I was just afraid if I got the turbo it would be a lot less than that. How many miles on your vehicle, and do you have a cumulative mpg (actual or computer) for as long as you have had the vehicle.
  • tinycadontinycadon Posts: 287
    occking, I have just over 7k miles on my XT, and yes, I've kept a running diary of my milage since I bought it. The 26mpg was my best highway trip, my two worst highway trips were 23.7 (winter) and 23.9 (running a/c). When I'm doing mostly city/urban driving that's where the turbo takes a bite, I'm getting between 16-18mpg, but when I have more suburban/rural driving it goes up to 20-22mpgs. The gas might be a little more expensive, but I don't drive more than 10k miles a year so it's wasn't really a deal breaker for me, I wanted to have a little more performance, I guess you could call it my "sin tax?"
  • occkingoccking Posts: 346
    Well, maybe I should have considered the turbo if I really could get that kind of mileage consistently. I travel approc 33 - 35,000 miles per year, lots of highway driving. Too late now!
  • tinycadontinycadon Posts: 287
    :( I guess the 1 saving grace is that the XTs are few and far between, I was lucky and got mine back in May when they were first arriving at the dealership, I've only seen 2 or 3 other 09XTs in the 10mos I've had it, so finding the exact 1 you wanted might have taken a long time :confuse:
  • ateixeiraateixeira Posts: 72,587
    Highway gearing is actually slightly taller for the turbo, but you'll still get better mileage in the non-turbo.

    On our 2.5X Limited PZEV we've seen 33mpg and broke 30mpg for a whole trip. At higher speeds it's usually 27-28, though.
  • occkingoccking Posts: 346
    Boy, I sure hope I can get that kind of mileage. So far, with 2800 miles approx am averaging 24 mpg, probably 2/3 of that highway driving. How long did it take your vehicle to get broken in before you attained that kind of mpg?
  • ateixeiraateixeira Posts: 72,587
    My wife hasn't hit 7k yet. It's barely broken in.
  • crv16crv16 Posts: 205
    12,000 miles on the clock now, and with summer gas, getting around 24-25 in suburban type driving - 28 mpg on the highway. It's bumped up a couple MPG over similar conditions when new.
  • occkingoccking Posts: 346
    Have had X limited two months now, just got back from a 1100 mile trip, 4 days from Prov RI up to Bar Harbor, ME over to a little past Montreal & back home.

    On first leg, trip computer indicated 28.5 actual was 28.1, that's a record, so far. On seconrf fill up trip computer indicated 26.7 actual was 26.5. Just got home now with a little over 300 miles since last fill up, trip computer says 28.2 to I figure actual mpg at least 27.5

    Of the 1100 miles, probably 600 miles at highway speeds, averaging just about 65 - 67, most of the balance "rural roads" perhaps 50 - 55 mph average, as far as "stop and go" maybe 50to 100 miles.

    Must say, so far pleased with the mpg, hope it continues to go a littler higher as I put more miles on the vehicle.

    The "negatives" on the car??? The rattles are beginning.... The cabin more noisy than I would like, particularly at highway speeds. You can't balance the front and rear speakers very well -- the rear speakers cannot be made very loud, bluetooth, you can hear fine but, just like with my previous car, people on the other end have a very difficult time understanding me; the cupholders should be round, not square, and actually a little too deep. Put a certain size coffee cup in and the lid sinks a little too low.

    Has anyone had this issue, and do you know a fix? I just hit 10,000 on my 2009 Forester, and my miles per gallon thingy (i'm sorry,, I can't remeber its official name) now reads -----. I looked in the manual, and thought perhaps I'd somehow managed to turn it off, but tried to follow the directions for turning it back on, and then really DID turn it off. Just empty space there. Turned it back on, and now have just dashes where the mileage used to appear. :(
    Would love some help. Will also post on the general 2009 Forester htread.
    Thanks very much,
    Sylviecat :(
  • ateixeiraateixeira Posts: 72,587
    FWIW it takes one driven mile before it displays anything.

    So if you reset it you may see the dashes until you drive 1 mile.
  • sylviecatsylviecat Posts: 10

    Does it reset itself at 10,000 miles? Or did I (or my sister who drive it Sunday) hit something inadvertantly? :confuse:
  • ateixeiraateixeira Posts: 72,587
    It works with each Trip Odometer.
  • occkingoccking Posts: 346
    Took two months to accomplish this. Actual MPG, 4890 miles divided by 197 gallons = 24.8 mpg. The trip computer has not been set since I got the vehicle & that is "hovering" between 25.5 and 25.8.

    I had a 2006 Tribeca and, if I recall (if you have Nav) after 10,000 miles it stops recording the time used, but, it continues to show avg mpg. What I do is leave one trip odometer alone and will not reset it until I get to approx 10,000 miles. The other one I reset every time I fill up.

    I have been able to record as high as 28.5 on the trip computer, actual best mpg for one tankful 27.9. It does seem to be getting better as I put on more miles, but could also be no longer using winter fuel.

    08 Forester PZEV

    18 tanks of gas
    214.14 gallons
    5382.4 miles

    Avg MPG = 25.13
    Tank high = 28.7
    Tank low = 20.9
  • Just purchased a 2010 X Premium with MT: driving home (conservatively as is my wont: between 50 & 65mph) from the dealer using two lane roads over 217.5 miles I got 29.2 measured mpg.

    I anticipate better when it's broken in a few miles down the road but I'm very pleased with the initial results for an AWD vehicle this size.
  • ateixeiraateixeira Posts: 72,587
    That's sweet, because usually they improve as they break in.
  • occkingoccking Posts: 346
    I am up to 26,000 miles now on 2009 2.5 ltd. MPG is dropping a bit as it always does up here in New England with colder weather. Mix is probably 3/4 highway and the balance "running around" MPG pretty consistent since day one per trip computer averaging around 26.1. Actual mpg based on miles driven and gas consumption perhaps 25.5. Pretty much what I expected. Highway mileage will certainly decrease somewhat if you go over 65 mph.
  • ateixeiraateixeira Posts: 72,587
    It's cold (brrrrr) here in the Mid-Atlantic so I'm sure it's bone-chilling up there. Mileage on my van has dropped, too. It's also taking longer for it to warm up.

    My wife's Forester has heated seats, so I'm jealous!

    It is ironic that I never posted under this thread with my fuel economy experience with the 2010 Forester X Premium MT I purchased in September. I posted in other threads, but not here. :blush:

    I averaged about 28.5 driving it home from Seattle to Fairbanks, Alaska (about 2200 miles) going 65-70 most of the way, but once I arrived here (to winter) and settled into daily routines, the economy dropped pretty dramatically. Now, during the winter, my monthly averages are about 20 mpg, with some tanks well south of that (lowest so far is 17.5) with mixed driving, but many short trips (~ 5 miles).

    This car LOVES to go 40-50 mph. Driving those speeds for 20 miles through the Whitehorse area on the drive home back in September netted me nearly 40 mpg, and a ten-mile drive through the Wasilla area a couple weeks ago increased my readout from 22mpg to a little over 30 (it had about 30 miles on it when I started the 40-50 mph stretch, which had a few stop signs/lights). Sadly, life is not long enough to go those speeds over the long haul. :P

    Total average now after ~7000 miles is 24.5 mpg, though I am more interested in the yearly average as the current (just a little over three months) is highly skewed by winter driving.

    Remind me, auto or manual? Best I've done is about 33mpg with our PZEV auto.
  • xwesxxwesx Fairbanks, AlaskaPosts: 11,000
    That was manual PZEV, but again, it was only 20 miles (and the 39.7 readout was on the display). Had I gone a whole tank at those speeds, who knows? As it was, I ran the remaining 70 miles (pure highway) before I filled up in Haines Junction at close to 70 mph. At fill up, I calculated either 30.4 or 30.8 - I can't remember which.

    My wife's '09 F-XT averages 10-13 L/100km, depending whether it's on the highway, or in the city, over the first 23,000 km of the vehicle. In Imperial (US) terms, that's 18-23 MPG, over the first 14,000 miles. That's just barely a touch better than I got in my '04 Toyota 4-Runner (V8).

    Naturally, it's a little better in the summer when it's not warming up for 5-10 mins, because it's -30 C outside, and we're not wallowing through snow drifts.

    For comparison, my '09 STI has averaged 10-13 L/100km, (exactly the same).

    I don't really care whether either car gets good gas mileage. We bought the cars for their performance, and AWD capabilities.
