I think theres no doubt that temperature will affect longetivity. The JD 3055 down here in Louisiana has 13,000 hours on the original engine and has been abused (oil chnages every 500 hrs or so, with no air filters changes/maintenance) and still doing well. Up in Maine/Vermont, you see alot of JDs the same size with the same use with only 4000-7000 hours. We alwasy have to change oil in our 2550 and 6410 from 15w-40 to 5-30 in the winter if we wanted to have reliable starting and then the issue of fuel gelling clogging the filters...... If I had a car I cared about, like if it was my Dads or grandads original 340, 440, hemi etc car, I would not start that below 40 or so. With the carbs and vaporization and oil viscosity, unless its my daily driver I would just hold off. 20w-50 is thick stuff, would not even consider trying to start our diesels with that in it without changing it out. We havn't used it since the late 80s. My

Yep. My '72 318 has lived its whole life in Calif and Western Washington. A few nights in the twenties is all the cold we get. 230,000 miles and it doesn't smoke at all. My '65 327 was in Anchorage, Alaska for only four winters. Lots of short trips. 125,000 miles and its a smoker...

well you know, just because you can start it up and drive it, doesnt mean that its a good thing. I think youd get a lot more wear and tear on a motor started at really cold temps.
You'd rather walk? 
no, i have other cars i start anytime any temp. im just talking about a fresh build (less than or around 1000 miles on) 416. I wanted to go for a cruise but I pulled the dipstick when it was about 38 degrees outside and the oil seemed think. so I didnt go for the cruise (I had the same urge and temp and result today). its not like i had to walk. if i did, i would most probably been driving.... transportation is important

I lived in Anchorage for several years. It doesn't really get very cold there very often.
You say it doesn't get cold in Alaska?
Alaska's a big place. Juneau ain't Anchorage ain't Fairbanks climate-wise. Anchorage is (relatively) mild. Seen days in the winter there when it was colder down in Texas. I used to wash my car during the winter there when we'd have a warm day in the 30s.

Some of us don't have any choice.

i just saw some places in alaska are hitting -20 degrees this week.
Been there and colder for the last 3+ weeks. Today it is up to 14 above and it feels like we are in the banana belt.  Supposed to be sub zero again for most of the next week.  Blizzard watch out for tonight and tomorrow with up to 6" more snow ontop of the 30 or so already on the ground and 35 mph winds will make it right interesting.

I had 20w50 in my D150 when i was up camping in VT a few weeks ago. There was a cold snap and it was 5 or 10 below over the night and the high was 12 that day. I had to move the truck in the morning so i had no choice but to start it.
It started right up but oil light took along time to shut off and the lifers sang for a wile. I just let it idle until it warmed up and the lifters shut up.
I wouldnt try and start a new motor like that unless i really had to.
I was asked to contribute money to help solve the civil unrest in Egypt, but I suspect it's some sort of pyramid scheme.

wind chill only affects warm blooded people/animals. It can drop the temp of an object faster than it would drop if there was no wind but it doesn't drop it below the ambient temp.
Right on RR 
Also guys keep in mind the clearances between things
are a lot different at cold temps vs hot temps. I'd freak out more trying to run a hot engine with no oil pressure at start up vs a cold one.
