Change from 0w20 to 5w30

Engine probably needs a tear down, piston rings are fried from running that swill 0w20.
I definitely wouldn't go to a 40 Weight but, will and do use 5w30 in my CX5 NA.
Are you guys using 5W30 synthetic or conventional?
This is probably the biggest reason for me to do so. There were times in the past I'd have three different oil weight for three different cars. Going to one weight is not only good for changes but for the occasional top up as well. It sounds like I'm not at risk of blowing it up
so I'm going ahead with the change.

yeah, you'll be fine. I thought of doing this when I use up my stash of 0W20.. my 16' Rogue is 0W20/5W30 wife's 20' Sentra states 0W20 but just a few years back Nissan was spec'd mostly at 5W30.This is probably the biggest reason for me to do so.

My next oil change will be Mobil 1 0w20 EP
But how's it do in the PF "cold flow races"?

I was going to make a comment on my thread about going from 0w20 to 5w30 but it's been locked:
I have a 2022 wrx that i like to drive spirited pretty frequently. On 0w20 I did notice minimal, but noticeable, oil consumption. The manual states 1L is normal every 3k miles. I noticed half of that.
I'm at about 1k miles with 5w30 and it started at exactly the full marker and still sits exactly at the full marker. I check on the same spot on my drive way every time.

It is very likely your manual states you can use 5w-30. It depends on the year, but Mazda has stated the Skyactiv 2.5 is good with 5w-30.
I have a 22 wrx with 25k miles and notice exactly the same consumption. About half qt every 3k. I might switch to 5w-30 now that summer is here. I noticed using subaru oil the consumption was worse than when I used castrol edge 0w-20. Only needed to add maybe 1/4 qt every 3k.
On our bought new by us Honda Element I ran either 0W-20 or occasionally 5W-20 from new to 70K or 80K miles. Been on 5W-30 ever since. Vehicle has 252K miles on it now. Still runs perfectly and "uses" just 1/8th quart per 5K OCI. No regrets on the 5W-30 switch, but I bet the motor would be just as happy and healthy had it lived on 0W-20 only.
