Late summer or in fall....because weather is nice and warm...and engine gets "fresher" oil for a winter...
Does It Matter What Time of Year You Do an OCI?

Very cool.
You should only change it when the planets are in perfect alignment with your Zodiac sign on the penultimate Tuesday of the winter equinox.
Went to Walmart today and looked at their oil but couldn't bring myself to buy a bottle of PZ at this time and drain out my 3 month old ST FS 0w20. I found info on youtube last night by Project Farm or something like that, that says ST is basically in the same category as as Amazon Basic, Castrol, QS, etc. So if I drained my ST it would be like draining away QS oil that had only been used for 3 months.
I will wait and run some PZ later on. I think it would be good to clean the engine with once in a while, and when I do, I may run it for a full year.
I may also run this ST for a full year. In the Spring I'm going to send in a sample of it for a UOA.

I change my oil whenever I get bored. It is a fun activity.
I seriously wish there was a local Oil Change Club. We could all get together, and change our oil all at once.
This site is the closest thing I have to that club.. or friends.
I am not making this up.

Yes. I might even do the unthinkable and run nothing but ST.
Poor car!!
No, it doesn't matter, why would it?
As soon as I realized that ST and Amazon Basic are both rated slightly higher than M1 and QS, that was the last time I'd ever underestimate ST oil again. It took a while to find and then absorb the info. I heard it from many people but Project Farm youtube videos are quite convincing.
All my warranties are up, so when my vehicles hit the mileage of my OCI I change the oil. There's a little wiggle room built in so if it happens in the dead of the winter I can pick my day, or run my oil filled electric radiators I have in the garage and do the oil change there.
I think if one were on the once a year OCI I would choose Spring because it’s nice weather. Probably doesn’t matter much in the grand scheme of things.
oilBabe’s RAV4 is on a 10k mile OCI and that usually works out to Spring and Fall give or take.
My Mazda3 is on a 7500 mile OCI and I’m probably due this or next week based on call volume.
We both drive about 20k miles per year.

0w30 for the winter and 5w40 for the summer for my Burb, so yes, spring and fall.

Yep. When it's -20F or +115F ambient, I do not want to be changing oil.
Choose wisely.

Please don’t take the nonsense on Project Farm seriously.
Exactly. The very definition of a worthless choice criteria.
