An old Porsche 911 typically requires a high-quality, synthetic oil with a viscosity rating of 10W-40 or 20W-50, depending on the climate and driving conditions. It's essential to use oil that meets or exceeds the specifications outlined in the owner's manual, often specified as API SG or higher. Regular oil changes and using the correct oil can help maintain engine performance and longevity. Always consult the specific model's manual for the best recommendations.
