As many others have said they do, I'm chasing price. These days I'm using Kirkland exclusively, because it's the best deal.
I run a relatively short 3000 mile OCI, so I don't really have to worry about long-life additive packages. With a short interval, any oil that meets the certifications is fine. I'm also okay with using jobber filters for those short intervals, because that's the kind of interval they're designed for.
