    Suburban commuting....

    Gee.. this discussion has become my own personal blog.. :)

    Last tank was 31 mpg.. Almost all commuting.. I attribute the increase to my wife being on crutches.. Easier for her to get in and out of her SUV, so less errand running for the Impreza.

    was 13.7 gallons, 390 miles, looks like 28.5 mpg on my calculator. Better than expected, and I am hoping as I get more used to it I can improve that.

    The fuel light was already on, so I guess that is a very healthy remainder when the warning light hits, something like 2.5 gallons.

    Mine is a 2009 OBS 5-speed.

    The fuel lights on my Outbacks were very consistent. They came on with ~13.5 gallons used. Unless there was a need to fill prior to seeing the light, I did not do it. Both my Caravan and Escort are not nearly so reliable; I tend to fill them up at a quarter tank just because I am never sure how much fuel actually remains.

    28.5 is great for a first tank! I think that is actually about the same as our first tank on our '08 Outback. But, most of that tank was my wife driving I-5 from Seattle to Salem at 65 mph. So, it was steady, mostly flat highway miles, and very little weight in the car. The trip computer read 33 mpg when we arrived in Salem, but, after loading the car and putting on another 50 or so miles, we were down to 29ish on the computer by fill-up.

    I like that the gauge also seems very reliable. It doesn't stay on full for the first 100 miles, then drop like a rock down to the last quarter tank, than have 3 gallons left below the 'E' line, as my Toyotas do.

    Half a tank remaining really is half a tank, 1/8 (when the fuel light comes on) really is 1/8, etc.

    The low-fuel warning used to come on with 2.3 gallons left, per Subaru, on my 1998 with the 15.9 gallon tank.

    I wouldn't assume it's 3 gallons, though.

    Both now have 16.9 gallon tanks. Funny thing is all Subaru's have the same fuel capacity, from the Impreze 2.5i all the way up to the Tribeca 3.6 H6!

    Are you sure? The owner's manual says 15.9 gallons for my car.

    Which would jibe with the fuel light coming on at 13.3 gallons consumed, as it has been.

    Oh, and the "3 gallon" reference was to my old Toyota, not to the new car. :-)

    The Forester's tank grew, to be honest I'm not sure about the Impreza. Anyone know for sure? It might be in the owner's manual under capacities.
  • nippononlynippononly SF Bay AreaPosts: 12,669
    My tank is 15.9 gallons, checked the manual again.

    And I refilled it last night, 14.0 gallons, 385 miles, for a lower average than last time, 27.5 mpg.

    The trip computer on the dash is about 1 mpg too optimistic.

    I will be working on getting my averages to 30.....

    My mpg gauge tends to be 1-1.5 mpg optimistic...

    Filled up today... gauge read 30.6, with actual being 29.8..

    I think the warmer weather, but not so warm that I use the A/C, is resulting in the good numbers... ..

    So did you notice that your mileage rose a bit after the first few thousand miles?

  • kyfdx%40Edmundskyfdx%40Edmunds Posts: 25,856
    Not necessarily..

    I think it seems more seasonal.. and being more cognizant of the mpg gauge.. :P

    Well in that case I am just going to have to try harder. Most of the time my gauge ran 28.5-29.1, and that resulted in 27.5 mpg, so I need that thing to read 31! Must. Drive. More. Slowly. :-P

    Go to Pikes Peak and only measure on the way back. :D

    Filled up tonight, 3rd fill so far (second if I exclude the suspect dealer fill when new ;-)), 348 miles, 12.9 gallons, 27 mpg right on the nose. I want it higher! I guess I need to slow down even more. Not yet though, I'm enjoying the new ride too much right now! :-)

    Once again the trip computer on the dash was optimistic, read 28.2 when I filled up.

    Is most of your driving suburban? Or is it mostly highway? Me, I'm suburban. I felt confident of pulling 29-30 mpg when I bought this thing, based on my experiences in other cars. The '97 OBS I had in the past pulled better mpgs than I am getting in the new one so far.

    I felt the same way about my '07 Outback. I kept pulling 27s, quite consistently, but really hoped for a couple more miles per gallon. My friend with the '08 Impreza manual got 31.5 on his last tank, primarily "suburban" driving. He tends to get a solid 30 most tanks during the summer, except when they have heavy city driving (which is rare). He and his wife split the driving about 50/50.
