Here are some basic tips to improve the fuel economy of your car. Maintain right tyre pressure This is one of the most ignored aspects, say experts. If the tyre is low on pressure, the engine has to work harder to maintain the speed and the balance, which burns more fuel. "A car owner can save 5-10% on his fuel expenses if the tyre pressure is maintained at the required levels," says Banwari Lal Sharma, AVP - marketing, CarWale Automotive Exchange. Most technicians keep the air pressure at 30 PSI, but refer to the car manual to see the recommended pressure for you car tyre. Ideally, an individual should check the tyre pressure once a week. Driving technique and Speed Many car drivers have a tendency to ride the clutch. Sometimes it is a technical glitch especially if one upgrades from a bike to a car. But some drivers tend to change gears too frequently, which also put constant pressure on the clutch. Ideally you should press the clutch only to change gears, or to bring the car to a complete halt. Clutch riding and frequent shifting of gears eat into your car's fuel consumption. "Aggressive driving, speeding, rapid acceleration and braking can lower your mileage by 30% on highways and around 20% on city roads," says Rupesh Rele, an auto expert. The exact speed limit to maintain a good fuel economy may vary from model to model. Drive in a gear that corresponds to the speed you're at. This means you shouldn't be revving the bolts off the engine, or crawling along in top gear. For a petrol car, you should follow the gear pattern of 10-15 kms for first gear, 15-25 for second, 25-35 for third, 35-45 for fourth and 50 plus for the 5th gear. As you speed up, you should reach the highest gear to optimise the fuel consumption. Engine Check Don't let the engine tachometer run beyond 2,500 RPM, especially in case of petrol cars. That is the maximum load an engine should take while driving on the road. "Often, drivers monitor the speed of the car but don't observe the tachometer of the engine. Letting it go beyond 3,000 RPM is a big no-no for any car," adds Rupesh Rele . A car owner should also undertake regular engine check-ups. A poorly maintained engine can consume up to 50% more fuel than an engine in good condition. Also, check the engine oil at regular intervals as prescribed in the car manual. The viscosity of the engine oil reduces because of non-servicing of the car. This will cause friction, damage the engine and lead to a bad fuel economy as well. Keep the car light Ditch the extra scrap in the boot, keep out the baby seat if you don't require, clean the car once a while to shed off any extra scrap, this way you can save up to 2% on your fuel average. "Often, when we change cars, certain spare parts or accessories are put by the service men in the boot of the car. The car driver, being unaware, just lets the extra weight hang in the car boot, which increases the weight of the car," adds Banwari Lal.
