New V70 gas mileage

    I just bought a new 2004 V70 2.5T. I've only driven it around town so
    far (no highway driving), and the computer is telling me that my
    average gas mileage is only 11 mpg. I expected substantially better
    mileage from this car. My dealer tells me that the mileage will
    improve significantly after the 800-mile break-in period on the
    engine. Is this true? So far, the car only has around 120 miles on
    it.

    Gas mileage in city driving is notoriously poor. Take it for a blast on the
    highway and I would be amazed if you see less than 30 Mpg. Give it a try and
    let us know.

    That does seem pretty low - I have a new XC70 (same engine, but heavier and
    AWD) and I'm averaging 17.5ish. Currently at 700 miles on the ODO.

    The engine needs to "break-in", but that seems a little low. How long
    have your "around town" drives been?

  5. My '01 XC70 gets 22-23 around town (10-20 mile drives on streets) and
    27-28 highway (long const. speed interstate). I never got less than 20.

    MPG does sound poor, but make sure you get out of town as soon as possible,
    within the next 100 miles or so and drive the car reasonably hard. The
    engine will benefit from breaking in as soon as possible. The trick is not
    to labour it, nor drive at constant low or high speed, but also to give it
    plenty of load with a wide-ish throttle opening.

    Personnally I would start with a rev limit of around 3500rpm until 500
    miles, increasing this 500rpm every 200miles, making sure you accelorate
    hard to this rpm regularly. Acouple of runs upto the impossed rev limit at
    full throttle in a lower gear will also help.

    Your mpg may possibly get worse before it gets better, but breaking in too
    gently will never see optimal mpg or engine life, you may end up with a
    motor which burns oil due to bore glazing.

    My 2.4 170bhp V70 gives me 28-31 mpg. It does short town journeys and
    high-speed (70-100mph) motorway driving. I'm fairly heavy footed.
    The air-con is working reasonably hard recently too.

    For peace of mind, check the tyre pressures and also that the car will
    roll if in neutral on a modest slope. If it won't then you have a
    transmission problem or a binding brake.

    What figures does the computer show on 'Instantaneous'? When
    accelerating you will often see single figures, but is should go to
    40mpg+ when easy cruising on the level.

  8. That equates to 25-29 US mpg.

    My drives have been mostly of the short shot variety. Picking my kids
    up at school, trip to the supermarket, etc.

    That sounds about right. Speaking of the computer, how can I get the
    display to change between "Average" and "Instantaneous"? It changed
    once all by itself, and I can't figure out how to change it back. The
    "Text Display" page in the owner's manual said nothing about this.

    On mine the left stalk has a twist-dial on it. As you rotate it the
    display changes through about a half-dozen options.

    Heh, not only is it in the driver's manual (are you illiterate?), but it's
    also intuitive.

    Also, for the record, my 2002 XC gets at about 38 MPG freeway (70 MPH cruise
    control), and averages about 18 in the city (lots of hills and stoplights).

    My 2.5 140bhp S70 will average 32-34mpg in mixed use driven reasonably
    gently, but some fast cruising on dual carriageways / motorway with lots of
    round-abouts at 80-100mph saw it plummet to 29-30mpg this weekend.

    I dont consider this bad at all for what is a heavy car when my Focus is
    doing only 2-3mpg better.
