Idling the engine for 3-5 minutes to warm up is more harm than good; the engine warms up the fastest when loaded, i.e. the car is driven. up to 45 sec of idling is fine, the oil circulates and lubricates the bearings.I do think regardless milage or how new, waiting 3-5 mins after starting in sub-zero ambient will do more good then touching key, dumping drive, and flooring it....
Cold oil is evil oil.
Besides, in some places idling the cars is illegal.
