i also have a toyota passo hana 2012 it is giving me about 270-280 km in full tank i dont know what to do i have done almost everything to improve its mileage and could you also please tell me how much does it gives in full tank. even though driving in eco mode dosent help on meter it gives me around 12.5-14.5 km/l but in reality it gives me 9.5 to 8.5 km/l i have cleaned the throttle body changed air filter, oil filter and ac filter but still no change at all my tyre size is 195/65 i have got them recently changed and still no affect
i change the fuel after every 5,000 km and i use zic A+ oil according to my tuning oil change and throttle body cleaner guy it is the best oil for cars like passo.
in 33 L fuel it gives me 270 which is quite less.
