I'm doing short interval OCIs on many vehicles, all based on time (6-12 months) with low miles (500-1000 or so miles each). Filters replaced about every 12-18 months or about every 2-3 oil changes. Here's my oil inventory to pick from and I'm curious what the crowd says may be the ranking based on your experience/information. I'm not opposed to using synthetic blends given the low miles I put on these vehicles.

Vehicles are all 10+ years old and high miles qualifying.

Any opinions on anything you personally really like and had great results with or do not care for or had bad results with, for CURRENT or recent API SN or NS+ categories?

5w20/0w20. It does get sub zero here but may not ever get low enough for 0w20 to be needed, but I can use it and am leaning toward putting a 0w20 before winter and then returning to 5w20 in spring.
* Quaker State FS High Mile 0w20
* Carquest FS 0w20
* Castrol Edge FS black bottle with titanium 0w20
* Castrol Edge FS extended protection 5w20
* Pennzoil FS high mile 5w20
* Pennzoil synthetic blend 5w20
* Carquest (now Fram) FS 5w20
* Valvoline FS Maxlife 5w20
* Costco FS 5w20
* Mobil1 FS High Miles 5w20

* Mobil1 Advanced FS 5w30

Blends for the dailys, full synthetic for the less driven, EP for the garage queens.

You could probably bump the OCI up to 5,000mi /1 year for all of those but maybe not the blends.

Dexos1 Gen2 approved for the GM's and other cars with direct injection, otherwise there shouldn't be an issue.

Unpopular and boring, but correct answer:

Use whatever you grab first. As long as your cars have no specific requirements beyond weight, it doesn't matter. They will not care and won't notice any difference between any of them.

I don't see the point of 6-12 month OCIs on cars driven 500-1000 miles. Maybe if the oil looks dark, but I can't imagine that with those circumstances. I mean, I last changed the oil on an old Corvette in 2016 and have driven it maybe 200 miles since. No hurry to change it still.

Why have you only driven a Corvette 200mi in 5 years?

Just been busy. And not like it's the most valuable or particularly exciting year to drive.
