Fact: For the average vehicle with a 3-litre engine, every 10 minutes of idling costs 300 millilitres ( over 1 cup ) in wasted fuel - and one half of a litre ( over 2 cups ) if your vehicle has a 5-litre engine. Unnecessary idling wastes fuel - and wasted fuel is wasted money. Gasoline is costly, its use has significant environment impacts, and there's not an endless supply - three good reasons not to waste fuel through unnecessary vehicle idling. For those who idle their vehicle for up to one hour at this location, just to get their vehicle washed, it's a good thing they are close to the Canadian Tire gas station !
