"Gas-powered cars need oil to keep their engines lubricated. When you start a car, an oil pump circulates the oil in less than a minute. But if you let your car idle to warm up the cabin, the oil will start to slowly drain away from the engine's key components since the engine isn’t moving the car."
IMO...It was way worse for an engine to be put under normal load while everything is cold. Oil is not flowing at the right viscosity and pressures and can cause lack of proper lubrication amongst other things??
I always thought extended idling of a cold engine and hard use of a cold engine both have potential problems... .
