^ doesn't the mileage have a large role in the peformance of the oil?
What I mean is if you change the oil frequently, well before it breaks down,
is there really little difference between a $5 and a $10 synthetic?

I tend to think it better to change your oil frequently with a respectable Porsche approved oil than to leave a more expensive oil in there for a longer period, long enough for it to matter.
