The following sections provide scheduled maintenance details for Porsche 911 models. Each section shows the recommended service interval, replacement maintenance items and includes the factory maintenance document. The service schedules and recommendations follow the factory specifications, however, we’ve added a few additional suggestions based on our experience with these cars.
No harm is done by more maintenance, other than the pain your wallet! However, a lack of maintenance can be significantly more expensive and have catastrophic results. A new set of spark plugs or a new air filter will always make your engine run better, regardless of what the recommended duration between those service items is.
Local Maintenance Requirements
It’s also worth considering that environmental and road conditions effect maintenance requirements. Negative wind chill in the northern states means you need healthy cold weather protection from your “lifetime” coolant. On the other hand, the problems of a sand filled air filter in Arizona, are unlikely to show up in New York! Seek the advice of an independent Porsche repair shop for local maintenance recommendations.
