Yeah, I'm not buying the notion that manufacturers have specified oil change intervals that are detrimental to longevity.
I used to get oil analysis done every year (I'd change the oil once a year) on both the Acura and TSX.
Every time the report would say viscosity is good, wear inhibitor content was good, particulates were within spec, etc. They'd always encourage me to go a few thousand miles more on the oil, and I was already going like 14k between changes.
Manufacturers these days have intervals around 7,500 miles (I think). That seems very conservative to me.
This was running 87 octane when the manufacturer specifies 91
