    O2 is oxygen MAF is mass air flow, both are at the intake. visit some diagnostic shop before anyone fiddle

    Also try different fuel station. Find the one which is less cheater. Most would be giving just 700-750 mls for 1 liter
    Be polite on the road. Always give way to others, particularly ambulances and pedestrians.

    i dont see people happy with the JDM cars
    (specifically on fuel consumption)
    i wonder why?

    a family sedan, a manual honda city would easily do 14km per ltr
    on the other hand people with JDM dinky's 660cc ones specially dont achieve that
    Life is short and very unpredictable just like a Quarter mile .....

    JDM's seldome run good on our crappy fuels. Even the HOBC is 97 rons, while imports require minimum 100 rons unleaded

    Yea buying JDM cars is a bit poker
    Let me share my personal experience
    Bought 04 vitz in 2008 now 1lac kms driven gives 11-13kms n engine suspension wise its 85%
    Bought 06 Axio in 2010 85k driven now it gives 14kms excelent response engine suspension etc 101% MashaAllah
    Bought 08 vitz recently n 9-10kms avg sound like a 2.OD maybe 1.3l wouldhave been better or to me Swift or city better option then this anytime

    @ keep your overdrive option ON always for better economy and drive with light foot on pedal.
    get your tank filled with the petrol pump which gives best economy. you have to test them and observe which petrol pump is giving you the best fuel

    why you guys always try to compare things at top level only. For comparing mileage all of following points should be considered:

    1) Car engine type and power cc. Like in vitz we have 3 generations 1999-2004, 2005-2010, 2011+. Now if anyone in general says my vitz do this much then how would you compare it with yours. Also 3 cylinder engine would give better mileage than 4 cylinder.

    2) Which mobil oil car uses. When I use 5W30 then I get around 30km's more as compare to when I use 20W50 which is not recommended for 1000 cc cars. Even Synthetic oil in same category as that normal oil also give 4-5% fuel efficiency.

    3) Tyre size of car also have impact on fuel economy. I am using 185/65/13 i.e. wider tyre.

    4) Which petrol do you use. I normally get 15-20 kms extra per tank when I use Total instead of PSO. However it doesn't mean that every PSO would be bad.

    5) The daily traveling route also counts alot. As I normally get 9-10.5 km/litre with AC. But my route is 5.5km 4 times from home to office and back to home (22 km daily). This 5.5 km includes 3 signals and 6 speed breakers :-). On long route I get 520-550 from 40 litres tank.

    6) Bad Wheel balancing and alignment can also cause you 5-10 % economy loss.

    7) Manual Car would always give you better economy than automatic.

    8) Bad fuel injectors can also effect fuel economy but in very very rare cases.

    9) Driving style can also save around 5% fuel per tank.

    10) Plugs can also cause bad mileage. They must be changed after 20-30 kms. If they have iridium tips then obviously they can last longer i.e. 70-80kms.

    11) Most important of all MAF and O2 sensors. You can check them through OBD device.

    12) Catalytic converter can also be cause for bad economy but in rare cases.

    13) Bad fuel filter can cause you some problems as well but it normally starts with other indications like car loosing pick, start problem etc and people normally get to it early and change it. But according to my personal view it should be changed after every 3 years atleast.

    14) Bad suspension can also cause fuel efficiency issues but in rare cases.

    15) Low quality transmission/gear oil can also cause efficiency issues. transmission oil must be changed after 40k in automatic cars and whenever you do it the jali within gear box should also be cleaned.

    16) Try to get your cars throttle body cleaned twice a year.

    17) Many people calculate mileage in very wrong way. The right way is to get your cars tank to full level and wait for it to be empty and then calculate km/litre.

    18) Loose or dead Timing/generator belt can also cause economy issues but to less extent only.

    I hope these points would definitely help you.
