Just bought an '82 SC Targa. First Porsche, happy man.
Handbook quotes 98 Ron for the car, but the garage the car came from (911 specialist) advised that ordinary 95 Ron unleaded is fine. Is this the case? Are there any issues re. timing, and, if either will do, is there any discernable performance advantage in using 98?
