12 Tips to save car Petrol

Petrol is costly these days, try these tips:

1) Pump up your tyre

Keeping your tyre inflated is one of the easiest and most important things one can do to improve fuel economy. Saving petrol means saving money.

If a range is recommended by the manufacturer, the higher pressure should be used to maximize fuel efficiency. Deflated tyres run hot and jeopardize safety. It will also cause the tyres to wear out prematurely, affect the vehicles adversely, and hurt the fuel economy by increasing the rolling resistance.

Tyres lose about 1 psi pressure per month due to air loss caused by the tyre hitting holes, bumps and kerbs. Therefore, the tyres should be checked at least once a month. Just 1 tyre deflated by 2 psi will result in a 1% increase in fuel consumption.

2) Drive at moderate speed

Avoiding high speeds on open roads results in safer driving and better fuel economy. In highway driving, over 50% of the power produced by the engine is used to overcome aerodynamic drag. Drag and thus fuel consumption increases rapidly at speeds above 90km/h. On the average, a car uses about 15% more fuel at 100km/h, and 25% more fuel at 110km/h compared to when it is doing only 90km/h.

However, this should not lead one to conclude that the lower the speed, the better the fuel economy – because it is not. The fuel consumption of an average car increases sharply at speeds below 50km/h.
