if you nail it from cold naturally metal expands minutley when hot so it will always be under a certain amount of strain when cold, also most engine oils are now designed to work as efficiently from cold as when warm, but you got to take the first sentence into thought, imo it is always worth waiting at least 30 seconds to let it warm through first. then you got the rest of the car to think of ie tyres as mentioned and drive shafts gearbox and the like. it is recognised that it takes at least 25 miles of normal driving for the car to be at working temperature that is the whole of the drive train. so in a nut shell your oil will work from cold as it should unless you use asda shit, and the car will always not like a good thrashing cold, as earlier comment of cold brittle metal
