Ever since 0w came out, i don't see a reason why NOT to run it in the winter. If it flows better even a little better then a 5w synthetic, i would switch.

You get THAT much better engine protection during start up. It might not be much in your everyday beaters but with a more expensive car/engine, i'd recommend it just to squeeze out those few extra miles of durability outta the block.

I don't know why, but this struck me as hilarious...the word "gullet". I'm really sitting here laughing hard enough it's hard to type.

I don't know where you are in MN but I live just across the border from International Falls and I was outside bout 10 minutes a go to let the dog out and had a look at the thermometer and it is -40 outside my house right now. I'd go for a full synthetic. In these temperatures your motor needs all the help it can get. The oil in my diesel will probably still be sludge when I go to start it in the morning and its 0W40 and its plugged in right now. I doubt it will run cause the fuel will be gel. Your motor will thank you as the oil will actually flow when you go to start it up. If you really wanna see go buy a L of dino and a L of synthetic and leave them outside on a night like tonight and try and pour them in the morning. The dino wont flow out very fast.

Use a full synthetic. Motor will turn over more easily.

I can't imagine how cold those temps would be to live in year after year. People in NYC complain when the temps get down to 20 degrees. I usually get a wicked wind chill being close to the ocean, but I can't imagine -40 F.

Got to -46 last night here. -30 right now in the morning. Gotta have synthetic around here if you want your motor to have oil pressure when it starts.

A block heater will do more good for your engine than any sythetic oil!!!! I lived in Winnipeg where the typical winter morning is -20c to -45c and have never run synthetic in any of my cars. Waste of money for most drivers IMO.
Use a good quality dino based on manufacturers specifications and a good block heater and your vehicle will have zero starting or oil pressure worries.

To be fair, it is different. The dry cold actually means you can tolerate a lower absolute temperature than a damp cold. But then once you start dropping below a certain point (say -20C to -25C), then dry or damp, it's [censored] cold no matter what. You just spend more time indoors on those days. Can't speak for other parts, but those excessively cold days are usually only a couple or three weeks total out of the entire winter here. But I do ensure I am winterized to at least -40 or lower (oil, coolant, washer fluid).

"full synthetic is a meaningless appellation these days - could be less than 20% "real" synthetic". The word means NOTHING. Go by specs. Many syn are not rated for exceptional cold flow. MRV under 15KcP at -40 would be a good start. PetroCanada makes some good looking extreme winter oils (spec wise), IN wally world: M1 AFE of course and EDGE, most likely some QS stuff too.

If the video can be believed, this shows M1 5-30 at -40F pouring vs a standard Synthetic blend. The full synthetic performs much better at -40. Here's the link under Cld weather.

Until they come up with some way to send electricity wirelessly to my block heater plug (for those times I'm not at home), I'll stick to synthetic AND the block heater.

Nice and toasty -40f below this morning here in northern Minnesota.
Glad I did not have to go anywhere and could leave the minivan with the blockheater and 0W20 Mobil 1 undisturbed in the garage.

Good Day,
Steven

I did that yesterday. I couldn't believe how thick the oil got @ 0*F

How bout 50,000 cP at -25F vs 50 at 100deg F. Definitely Honey like and getting near Grease consistency. 0F is a cakewalk. Some Arctic "real" synthetic 95% PAO oil is good to flow at -65, but --40C/F should work for most of us not seeing temps regularly below -20F.
