How to improve the fuel efficiency of Toyota Vitz 1999?
I own a toyota vitz 1999 & I am worried a lot about the fuel economy. It gives me only 10KM/Ltr without AC.
I did everything to make the fuel efficiency better (get the spark plugs cleaned, throttle body serviced, ATF changed, tires changed, air filter changed etc. ) but still I am getting very low mileage.
Can you guys please suggest me any treatment/remedy for this problem? CNG kit is installed also which gives about 150KM/cylinder(55) without AC.
