Drive between 45 and 55 kmph.
It has been established by trials that you can get up to 40% extra mileage at 40
kmph as compared to 80 kmph.
Avoid accelerating or decelerating unnecessarily.
Incorrect gearshifts can lead to as much as 20% increase in fuel consumption. It
does not matter whether it is a petrol or diesel car.
For city driving, change to a higher gear when you are sure that the engine will

can lead to a 2% saving in fuel, when driving in the city. Lighten your load even
if your car is claimed to be the most fuel efficient petrol car in India.

faster wears of tyres at the sides, whether it is a petrol or diesel car.
