    Default Toyota vitz 2011 giving very poor mileage.

    Salam brothers,
    My vitz 2011 new shape has been giving me very poor mileage since I bought it a few weeks ago. It is giving maybe 7-9 km/l in city! Even prado gives better mileage than this! I have changed oil filter, oil etc. but still is sub-standard. I mean it is very frustrating to fill gas tank full for 4k rs and then have it finished in a blink of an eye. How to improve mileage? I thought vitz was supposed to be small economy car it turn out to be bull$%^@!

    Let us start with the basics: How are you measuring the fuel consumption? What is the history and mileage of the car? Is the CEL on?

    from the meter/gauge that tells avg. fuel consumption. when i fill up the car it tells range 350km/45liter. Don't know about history and mileage is "14,000" obviously tampered. CEL light is not on.

    The proper way is to fill up the car and note the odometer reading. Then drive for more than half a tank at least, then fill up and note the mileage. Distance traveled divided by liters consumed is your actual consumption. Also, are the tires stock sizes?

    - don't rely on ECU readings
    - get it checked with toyota 3s or any authentic pit shop with good computing gadgets... [2-3k exp]
    - check the tire pressure, brakes, gear oil etc
    - r u changing gears or trying hypermiling, if yes, then stop that
    - r u a heavy foot driver?. . .where exactly r u driving [your daily route]
    people who use Highbeams.. once day would suffer too bigtime. People who drive slow on fast lanes, remember one day a vehicle carryin ur son, dad might get late to hospital coz people like u. underaged driving will land u in bigtime trouble one day or the other.. And the Blue indication light on ur speedometer denotes "High Beams"

    Ok I am thinking about taking it to toyota indus to get sorted out. Oil was recently changed, so I need to change CVT oil?
    Also there is a green light that says ECO, when driving conservatively it switches on so I try to drive within ECO light. I have since tried hypermiling after the bad mileage. I mostly drive within the city.

    Bigger tires will require fewer revolutions to cover the same distance, so your odometer will read less than true distance. You will need to correct for the error induced by the non-stock tires before your calculate the consumption.

    A different size can easily change the rolling diameter by 5% or more. Please see this:

    Salam.

    Is that average achieved with the AC on or off?
    Turbo lag is like foreplay. You know it's coming. And it's gonna be good.

    i believe your car need an alignment, misalignment increase car consumption, other then that engine settings matters,. get your car tune up from a good japanese mechanics.

    Check for Catalytic Converter if it is choked or okay ....

    Toyota can check it for you and be able to tell about the health of Catalytic converter. It plays an important role in fuel efficiency

    I will second Umair2203 suggestion to check the Catalytic Convertor as it play's a vital role.
    Symptoms can be poor engine performance , car achieving very low mileage.
    You can try the product STP Fuel system cleaner or if you can source CATACLEAN
    If you are going to Toyota garage the only glitch is they dont have a solution to clean out the Catalytic covertor other then breaking it a new Catalytic convertor is very hard to find plus quite hard to install. So the above 2 cleaners will really help you in fixing this low mileage issue.

    Also just get the Throttle body serviced out & keep 30 psi in all 4 tyres.

    All the best
