Best question so far. What does the owners manual say?
If it was mine I’d say 5w30 QSUD and forget about over analyzing things.
5W20 Under 45 Degrees F. ?

Franklly I live in the PNW and I'd run 10w-30 without any worry.
A heck at my work we have saw -16F few times. No issues using a rerefined 5w30 in lots of stuff. Must be doing something wrong eh
Some of those aren’t actual SAE grade designations, and an appropriate winter rating is determined solely by the starting temperature, not operating temperature.
Just for fun! I always read the owners manual then for winter summer recommendations,I’m retired
That's all true. However, if I lived in the PNW, I'd make winter trips to remote destinations where temperatures could easily get quite low.
5W30 is allowed for both my Kia / Hyundai vehicles in my sig (although the oil caps of both are stamped “5W20”). Interesting to note that unless you drive I-5 or I-405 it’s just one connected neighborhood after another driving at 35 MPH the whole time . I see my share of vehicles that once they accelerate will burp up a noticeable cloud of brown smoke which I attribute to a lot of slow suburban driving with shorter distances . Severe Service OCI at its best !
Even
There's practically nowhere in Washington where it gets below 0f including Mount Baker or in the eastern side of the state up by the Canadian border.
Nice chart. Thanks!

Pick a good 0w20 for year round use. Mobil 1, Pennzoil platinum or castrol edge
Why would that be considered "newsworthy"? The vast majority of H/K engines have not been replaced and will continue to give good service until they're scrapped for other reasons. Pick any vehicle brand that's mass-produced and I'll show you statistically significant engine failures in their history.
I e learned to not believe or listen to what tripleseven posts. It’s all opinions, no facts
As I said previously in this thread...I'd stick with 5w30 in the OPs situation.
Since there is a lot of discussion about 0w20 vs. 5w20 going on here I'd like opinions on using 5w20 synthetic
in my daughters Mazda which specs 0w20. Reason being I have some 5w20 Pennzoil Ultra that I'd like to use.
In my neck of the woods single degree Fahrenheit would be the absolute coldest encountered and that would only be a few times a winter. In the teens and low 20s are the morning norm. Would 0w vs. 5w make any difference at those temps?
For what it's worth my daughter rarely does any short trip driving....she usually drives a minimum of 20 to 40 miles each time she starts the car.

That's what I was hoping to hear. I also remember the PQIA test of 5w20 PU showed it having very good cold weather properties.
