My 2009 Toyota Corolla Altis 1.8J (Petrol) is delivering low fuel efficiency even on 100 octane fuel.
I have bought this car from a friend. It is in really good condition but the car delivers just 16.47 mpg in city and 30.25 mpg on highway (I have calculated using tank full to tank full method) also I have been using 100 octane fuel in the car and was expecting more fuel efficiency.
