My engine will go thru a series of Revs, On a cold start it'll be about 1700-1800 for about 8-10 seconds, then it'll drop lower to about 1500, and doesn't go down till you tap it. Letting the car idle for any extended time (15 min + ) isn't good for the motor. Going to 5w-30 for 45f temps? Isn't it supposed to be colder then that in CT?
Some logic behind this is
a) Get oil pressure up
b) Keep from stalling due to sludgy oil
c) Get into operating temperature range quicker
I had 10w-30 in till monday, when i did my oil change, the 10w-30 was getting pretty black recently (good, that means it'* cleaning) I don't know if it was from our long time below 0 or what though. It does start much better on 5w-30 Synthetic then 10w-30 syn, or 5w-30 Dino.
Lifter clatter might mean you don't get oil to the top quick, when i switched to Mobil1, mine basically went away. I do get it still since the oil drains down more when shut off, but it also gets up top better too.
