Considering the following facts:
- Synthetic oils are better in every way than dino oils
- The Boxster uses synthetic
- The Boxster uses 9.25 quarts, nearly twice as much as the average engine, with the obvious advantage volume brings
- Porsche reccomends 15k mile change intervals on the 986
- The 3000 mile change is a farce continuing to be perpetrated on us by the industries profiting from it, but still coloring our views
- It has been shown that *fresh* oil is actually more damaging than reasonably dirty oil
- We've seen independant oil test that show the oil to still be fine at extended intervals
Unless you're tracking your car a lot, I don't understand what the nervousness is all about. 10k mile intervals are *very* conservative. Relax.
