Yeah, I love/hate the all aluminum motor... warms up into the "normal" range in 5 minutes... but also cools off just as quick!
Sure sucks when it's -10�° or less and your car sits for 15 minutes and it's pegged on the cold side again.
I usually wait about 5 minutes or so... start the car, brush/scrape snow/ice off. If I just go right away, I can barely shift it.
