Fuel efficiency has become a major concern for Indian cars. With the rising inflation and increasing pollution, Indian car manufacturers are experimenting with various technologies to design beneficial and fuel efficient engines for their respective car models.

Researches and studies have come out with various techniques and measures to stretch a liter of fuel and increase car mileage. Every liter of stretched fuel adds to the overall fuel economy of both the old and new cars.

Indian roads are congested with a number of fuel efficient cars but still there are certain measures that further helps to improve gas mileage and improve fuel efficiency.

• Acceleration: This plays a vital role in reducing or increasing fuel efficiency. Slow acceleration uses more fuel. It is advisable to drive the car at a desired speed and then considerably change the gear.

• Car Weight: Weight of the car also affects the mileage. Extra weight loaded in the car trunk puts extra pressure on the car engine. This eventually results in higher fuel consumption.

• Cruising: Engine speed also impacts the fuel economy of Indian cars. Use top gear from around 60kph, maintaining the car speed between 2000 rpm to 3000 rpm.

• Driving Route: Continuously stop and start motoring results in more fuel consumption.
• It is good to choose a traffic free route for driving to the desired destination. If in case driving in traffic, maintain a slow and steady speed.

• Hill Driving: Don't try to raise the car speed while driving on a hill. On a hill car engine works harder putting in extra pressure to overcome gravity and increasing the speed can increase pressure and worsen fuel economy.

• Tyre Pressure: Car tyres with high pressure help in increasing efficiency by reducing the pressure on the engine. High pressure tyres have lower rolling resistance which helps them to run smoothly on road with less friction.

• Wheel Alignment: This activity greatly helps to reduce the rolling resistance of the tyre which eventually helps to increase mileage.

• Accessories: Accessories like stereo, rear demisters, air conditioners and DVD players add to the fuel bills. When these are working, car engine requires more pressure to keep the car running. So, use these accessories when required. Don't just switch on the stereo and stand outside the car waiting for someone. Remove roof rack if not required as this lowers the aerodynamics of the vehicle.

• Engine Tuning: Incorrect fuel ratio and ineffective spark plugs also affects the mileage. It is good to tune the engine and fix any major issues like faulty oxygen sensor and ineffective ignition system.

• Air Filters: Clogged air filters also reduce mileage. Replace such filters and prevent impurities from damaging the car engine. This eventually helps to increase fuel economy.

• Engine: Change the engine oil at regular intervals of time. Also ensure that the oil used is recommended by the manufacturers because an incorrect grade of motor oil can hamper the fuel economy of the car.
