Oil analysis is about the cost of an oil change for most people and sometimes says change the oil so most people just change the oil. For some it makes sense to do oil analysis.
Otherwise you're talking about extremely rare one-off cases where someone's car happened to be in just the right environment and built just perfectly the whole time. I'm not talking about "that one time one guy in a forum five years ago said his car lasted 120,000mi without an oil change", I'm talking about normal advice for normal car drivers.
No OEM car manual says this is recommended.
> Normal Service – Up to 25,000 miles (40,200 km), 700 hours of operation or one year, whichever comes first, in personal vehicles not operating under severe service.
That said, this still goes against the person who I was originally commenting about. They suggested going 2+ years between oil changes, and while the mileage does fit here for the average car the timeframe doesn't.
You're also technically 1,000mi short from my ask but I'll grant if it actually is OK at 20,000mi it's probably still OK at 26,000mi.
For most people oil analysis and their filters is more expensive than just changing the oil.
My modern car recommends synthetic changes at 7,500 miles by the book. Sending off samples to the labs, it looked good at that point but started to get some bad degradation at about 11,000mi. It would be sludge a little after 15,000mi and would have probably destroyed the engine before 25,000mi
