It depends on the state of your engine, and how you drive it, etc.

The _only_ reliable way to do it is to take a sample of the oil and get
it analysed.  It's cheaper to do a change regardless.  The only economical
way is to look at the oil on the dipstick and smell the contents of the
cam cover.  Takes practice, but it's fairly reliable.  Fundamental -
if it smells like sh*t, it _is_ sh*t.

Intervals are for leasing companies and lawyers.  If the engine is
_your_ property and _you_ stand on the line for any $$$$ - it's up to
you.  No one can assume that responsibility.
