Well some claim the oil is too "thin" and only used to meet EPA regs. The cite the rest of the world being recommended to use 5w30 or higher. It really is more keyboard conjecture than real science.

You also live in an area also known as Canada. Or close to it. To far north to need a thicker oil cause of higher ambient temperatures.

I have run 20w50 in my NA's for years change every 3kish and never had any issues. Even when I used to do 50K plus a year delivering pizza.
