Here are some basic statistics on Engine Idling:

• Average passenger cars burn about 2 litres of gas per hour when idling.

• Every litre of fuel produces 2.4kg of CO², the main greenhouse gas.

• Each hour of idling is equivalent 50km of engine wear.

• Idling engines are inefficient due to low combustion temperatures.

• Extended idling causes fouled spark plugs and other ignition problems.

• It is less expensive to shut down and restart than to idle for 10 seconds... even when taking the "starter wear" into account !!!
