No, because every oil analysis I've done (not many) has been reasonably
good.
It takes destructive testing to really analyze. I just think my frequency
of oil changes are cheap insurance and has worked for many cars for many
years.
And how (environmental, too) the engine is used makes a big difference.
Better to be conservative, in my opinion.
