> 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 25,000mi it's probably still OK at 26,000mi.
You missed the bypass filter. If you add that to your engine you can replace the yearly / 25000 oil change with oil analysis, if that comes out okay just change the filters (replacing only the oil in the filter), thus not doing a full oil change. . If you only use their oil then 25000 miles is 1000 miles short.
For most people oil analysis and their filters is more expensive than just changing the oil.
No OEM car manual says this is recommended.
