It increases the friction between the tyre and the road. Similarly, over-inflation in tyres reduces the grip. Therefore, keeping proper tyre pressure as recommended by the manufacturer is inevitable. Improper tyre pressure can reduce almost 10-15% fuel efficiency. Drive with the correct air pressure to increase car mileage a car’s fuel efficiency and, thus, greater mileage.

7.  A half-full tank may increase mileage

Fill up your car’s fuel tank halfway. It is good to keep a car’s tank above one-quarter full. A half-full tank may increase its mileage. A half-full tank reduces the weight on the engine and increases mileage.

8.  Roll up Car’s Windows

The wind blow coming into the car from open windows can hamper a car’s aerodynamics and cause more stress on the engine, especially at high speed. A speed over 50 kmph and fully open windows can cause low fuel efficiency. You can use the car’s air blower at the ‘fresh air setting’. 

9. Keep your Vehicle Light

Avoid putting extra items in your car; it can improve your car’s fuel efficiency. Leave excess weight at home. You will notice top mileage cars with improved efficiency which are ideal for daily commutes.
