Fill out your location....that might give some of us a little better understanding of the temperatures in your region. 40*F is pretty cold to my grandfather down in Miami while it's just "cool weather" to my other grandfather in upstate NY.
the main thing is to allow 1-3 minutes for the oil in the pan to get pumped to the top and begine lubricating. This takes about 20 seconds in warm temps and longer when its 10* out. Let idle a min. of 1 minute and then put it in gear and go but drive it like granny does that first mile. It will build heat in the engine much faster going down the road.

I usually just go by the sound of the motor. I drive like a granny until it sounds normal again. I try to let it warm up but ever since my remote start stopped working I've been too lazy to go outside and start it before I'm ready to leave.
