    My only thought it that you forgot to mention what your MPG is...we are not
    psychic. TG

    Uphill, five passengers, towing two jetskis, with low tire pressure and
    the a/c on? Seriously, you need to provide more info. When did the
    "horrible" gas mileage start? Mileage? Service? Driving habits?

    More informatin is needed... key thing is to determine or know what Miles
    per gallon your are getting. I am sure you have done it already, but if
    you have not... fill up the tank and get a least a 100+ on it. Fill it up
    again and divide your miles by the number of gallons.

    I have a 97 Subaru Outback and its gas guage has slowly gotten less accurate
    over the years. It only takes about 30 to 40 miles to drop it from 1/2 to a
    1/4. I then gets about 150 miles out of the last quarter before the light
    comes on. One thing I like to check is that the light is coming on at the
    right time. Your light should come on when there is still 2.5 gallons
    left. If you fill up close to when the light has come one, you should put
    in around 13 gallons as the car holds 15.5.

    Please also include information on different sounds the car is making. Is
    the car lacking power? Are you noticing any smells or different color
    smoke coming from the exhuast? So on...

  6. Yeah. If you can't supply any more information,
    go bitch at your dealer and leave us alone.

    My gage has started behaving even more erratically. Recently it
    dropped from 3/4 to 1/2 in a couple miles. And on one 100 mile trip,
    started with plenty of gas. it dropped from 1/8 to well below E,
    stayed there for a while and then slowly rose to above E (a little) by
    the time I got home. Haven't run it to the low fuel light recently
    and on the above occasion it took 12.5 gallons.

    Since the originator of this thread has never responded, maybe the
    idea of an erratic gage set off bells and answered his/her question.

    Sorry All,

    The car belongs to a friend. He drove over the weekend about 70 miles
    and he started on a FULL tank. Upon arrival, the gauge read 1/2 (after
    70 miles remember). He is not so observant, so he could not answer all
    the questions you all asked above which I asked him already myself. He
    just stated the poor mileage has always been an issue. But I think that
    the gauge being faulty is an issue (I'll have him check the 1/2 to FULL
    amounts in gallons when adding to check the accuracy of the gauge).

    I have never had exposure to Subaru (riding in, working on) till this
    past weekend so I posted the (information-less) post. I have only ever
    worked on every other Jap car since 1976 so I thought the Sub-posters
    could give some Brand-Awareness "hints and tips"

    Thanks All !!!!

    You posted here about "HORRIBLE" gas mileage on behalf of a friend who
    is not very observant about his gas gauge?!?!?!?

    Yes that is true. Some people you know (including men not just woman)
    just know about where the gas goes and how to start and drive the car :)

  11. The gas tank is NOT a cylinder or regular shape. It is cone shaped on the
    bottom... so the rate of change of the gauge on the dash is not a good
    indicator of the actual proportion of fuel left in the tank.

    Also, a "top off" fill will use the line between the tank and the gas cap
    which is not counted in the gauge. So the first portion of a gallon does
    not change the level indicator at all.

    You need to fill it all the way, then keep receipts and write the milage
    down on each one, then sit down and make a chart. That's the ONLY way to
    get an accurate idea of your milage. Then, of course driving style, drag,
    wind, moisture, city/country, etc. will affect the milage.

    A drastic drop in milage can mean mechanical problems, but you won't find
    that until other factors are controlled for.
