12 Tips to Save Petrol

1) Pump up your tires.
Keeping your tires inflated is one of the easiest and most important things
Saving petrol means saving money one can do to improve fuel economy. If a
range is recommended by the manufacturer, the higher pressure should be
used to maximize fuel efficiency. Deflated tires run hot and jeopardize
safety. It will also cause the tires to wear out prematurely, affect the
vehicles adversely, and hurt the fuel economy by increasing the rolling
resistance. Tires lose about 1 psi pressure per month due to air loss
caused by the tire hitting holes, bumps and curbs. Therefore, the tires
should be checked at least once a month. Just 1 tire 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.

3) Clean the air-filter regularly
Clogged air filters increase fuel consumption by restricting airflow to the
engine, and thus should be cleaned/replaced when necessary. Clogged air
filters can increase fuel consumption by up to 10%.

4) Use thinner tires
Tires with thick width will improve the handling of your car. However, it
will also increase your car’s fuel consumption. Thicker tires mean more
rolling resistance! , and thus will consume more fuel.

5) Start up the car properly
With today’s cars, it is not necessary to prime the engine first by pumping
the accelerator pedal repeatedly. Do not crank the engine excessively This
only wastes fuel. When starting the engine, idle it no more than 30 seconds
to warm it up. An engine will warm up faster on the road. However, avoid
sudden acceleration before the engine has warmed up sufficiently.

6) Drive in high gear (overdrive)
The engine runs most efficiently between around 1,500 and 2,500 rpm. To
maintain these low revs you should change up through the gears as soon as
practical and before the revs reach 2500 rpm. For automatic transmission
cars, you should always switch on your overdrive to help save fuel.
Overdrive will allow your engine to change gears at lower revs. It also
puts your transmission into an “economy” mode and lets it engage the final
“overdrive” gear when cruising to ! keep the rpms extra low, thereby
increasing fuel economy.
