-35c Would be rare but winter months average -10 easilyHow often does it get down to -35 in Toronto?

Sure it does, for cold starts. As one who has experienced the real struggles of bitter cold operations in Alaskan winters, cold startup can be a real problem. Especially with the wrong oil adding to the issues.
Agreed, but a 0W is good for the cold starts in the winter temperatures we experience here.If it’s -30 outside but the engine is at operating temperature, the ambient temp has no real effect on the performance of the oil. The oil temperature is what matters.
Oil temperature is not well regulated like coolant temperature is. Ambient temperature makes a big difference to oil temperature. Even on a car like mine with an oil-to-coolant heat exchanger, steady state oil temperatures will be 80 C at -35 C ambient, and 100 C at 35 C ambient. The difference in viscosity at these two temperatures is about the same as the difference between a 0W20 and a 5W40. In vehicles without an oil cooler, the difference in oil temperature would be even larger.If it’s -30 outside but the engine is at operating temperature, the ambient temp has no real effect on the performance of the oil.

This where I always get confused. If both perform the same at this cold of a temp, why does 0W-20 even exist? I believe it is only for the fuel mileage benefit but since they are both a 20 grade at operating temp, the fuel mileage benefit must be realized at the time of a cold start and the initial warm-up period. If that benefit is in fact realized, wouldn't that mean that the 0W-20 is less vicious and is allowing the engine to operate easier and therefore use less fuel and isn't that a good thing? When manufacturers are making their miles per gallon claim, how and at what temperature do they measure it?At -10C either a 0W or a 5W winter rated oil will perform the same. There's no guarantee that at that temperature either one would have superior cranking performance and pumpability.
Well any oil that gains a 0W performance rating will perform the same as another oil with the same rating, within the tolerances of the requirement. Above the temperature of the test there is no guarantee that any oil with a 0W rating will be thinner or thicker than one with a 5W rating.This where I always get confused.

Google this: HTHS wear graph.Hi folks. The owners manual on my my 23 Elantra 1.6hybrid says the oil should be 0w20 BUT it also says consider using 5w30 with warmer temps (the image looks to like they identify anything above 5c as ‘warmer’. it says 0w20 is better for fuel economy. The oil fill cap says use 0w20.
I live in Toronto … should I just stick to 0w20 all year or fill with 5w30 for the summer months? Or is it wash either way and I’m just overthinking this?
evidently you can't use **** on this site and is against the rules.0w20 is ****, go with 0w30
It's a shame you have an inability to express yourself without using asterisk-producing language. Your sentence structure needs improvement as well.evidently you can't use **** on this site and is against the rules.
Oh thanks. Hows the bay area smelling these days, still like cat pee? I dont know how to type all that good, but I know not to live in a place that smells like cat pee and burning sugar. And of course, void of most liberal snowflakesIt's a shame you have an inability to express yourself without using asterisk-producing language. Your sentence structure needs improvement as well.
