How to make every drop of fuel count

Plan your route. Know your short cuts and avoid rush hours where there will be traffic congestion.

Inflate your tyres regularly. Under-inflated tyres use more petrol.

Travel at a constant speed as this keeps fuel consumption constant too.

Do not speed. Fuel consumption increases rapidly at speeds over 90kmh.

Wind up all windows to make your car more aero-dynamic.

Switch off your engine if you are stationary or when waiting for someone.

Clear your car of junk. Extra weight on the car increases petrol consumption. Alternatively, decline taking on passengers.

Use your air- conditioning and other on-board electrical devices such as mobile phone chargers sparingly.

Make sure your petrol cap fits tightly. Petrol can easily evaporate if the cap is not airtight.
