That’s like asking what is the best religion, or sports team, or…
The manufacturer’s Oil Life Monitor will give adequate protection, for the majority of owners, throughout the “design service life” of the vehicle. (This last is proprietary to the manufacturer, but around 150,000 is a good guess.)
I, however, choose to drive my vehicles much further–double the design life, 300,000, is a good round number. Accordingly, I change my oil about every 5,000 miles. I bought my car (2008 Cobalt) from PENNDoT, and they had stickered it for 5K oil changes, and it was running good at 207k mi…so I went with that–figured their needs and mine closely match, and they MIGHT have more experience with their motor pool than I have with one car.
Also remember that the OLM assumes you’re using whatever house brand oil (or equivalent) recommended…in my case, DEXOS I. If I use “whichever’s cheapest API S[whatever],” I’m not guaranteed to get good service out of my oil for as long as the OLM says I will!
If I were using JL’s bulk oil and “brand X” filters…I probably wouldn’t go much more than 4,000 miles…after which, I would never darken their doors! (Way too many horror stories about undertained, underpaid lube techs trying to “hard sell” added services for me, TYVM.)
