Work out vehicle idling cost instantly with clear inputs, formula shown and shareable results.
Idling burns 2-4 litres an hour in a truck and produces no useful work at all. Ninety minutes a day across twelve vehicles is 10,800 litres a year — enough to fund telematics and driver coaching many times over.
Idling cost
litres = idle hours x idle rate x working days x vehicles; cost = litres x fuel price
Not on a modern engine. Driving gently warms it faster, and prolonged idling causes bore glazing and diesel particulate filter problems.
That is a genuine need, but auxiliary heaters and battery-powered systems do the job for a fraction of the fuel an idling main engine uses.
