Saving Petrol – An Overview

Ensure that your engine is in proper working condition. This would reduce the fuel required to work the engine. Regular servicing would obtain maximum efficiency for the vehicle. A dirty engine could increase fuel consumption by 10 to 20% while a clogged air filter increases 10% of fuel consumption. The air filter and the fuel filter should be kept clean. Use new filters if required. Installing an oxygen sensor could improve mileage by almost 15%.

Feed multi-grade oil to your engine because it reduces drag. Change the oil regularly. Certain engines work optimally with different kinds or grades of fuel so do refer to the vehicle manual.

Avoid running engine idle for a long time. The engine warms up faster while driving so there is no need to wait for it to warm up before moving off. If your engine uses petrol as fuel than it’s more efficient to turn off the engine than to run it idle for more than 30 sec.

Go for the four-cylinder engine rather than going for V6 or V8. Light cars consume less fuel than large vehicles. Before buying a new vehicle look at its rated efficiency.

Close Windows
Open windows increases resistance to wind flow that increases fuel consumption by as much as 20%.

Grade of Fuel
Fuel tank caps that are either loose, damaged or are not there at all, cause petrol to vaporize. Close the cap properly every time you open it.

Air pressure in tyres

Poorly inflated tyres cause wastage of fuel as well as wear and tear of the tyres. Check your vehicle’s tyre pressures at least once in a month. You can refer to the specified tyre pressure label around the driver seat. Use radial ply tyres instead of cross ply ones because they offer comparatively less rolling resistance and longer life. Ensuring wheel alignments are proper gives 10 percent saving of fuel.

Plan your trip
Try to plan your trips during less-congested times of the day whenever possible. With less traffic, you can maintain a smooth engine running without having to apply harsh brakes. You can use the internet to check out the shortest route to your destination. Never put extra luggage on car’s roof rack as it increases weight. Road and weather conditions also play a major role in the fuel economy of your vehicle. Driving on a plain road can reduce fuel economy by as much as 6 percent. On the contrary on a road with upward slope causes 7 percent loss of fuel. Examine suspension and chassis parts for misalignment such as axles, bad shocks, bent wheels, or broken springs.

Air Conditioning

As vehicle speed increases, air resistance increases in an exponential fashion. While going on long tour try to maintain constant speed it improves fuel efficiency. Use the A/C it when required. With A/C on, an extra load is placed on the engine forcing more fuel to be used by about 20%. Furthermore, the engine runs inefficiently when it’s cold.
