Intervals are whichever comes first, miles or years. "Porsche factory (converted from km)" means Porsche's own figure for another market, turned into miles with the same km-to-mile pairing Porsche uses in the US. Your car's own maintenance booklet is the final word. HBi Auto's recommendations for cars that are tracked, driven hard or stored are being added by our service team.
