Porsche 911 Turbo Maintenance Schedule – 991

Porsche 911 Turbo 991 maintenance or service schedule intervals with details of the time and mileage intervals or maintenance items to replace. We include the original Porsche maintenance schedule documents and some additional recommended maintenance intervals for your Porsche 911 Turbo 991.

Recommended Time and Mileage Based Maintenance Service Intervals for Porsche 911 Turbo – 991

Porsche 911 Turbo | 2012 – 2019 | 991

Standard maintenance on the Porsche 911 Turbo 991 models is very straightforward and well laid out. There are additional items recommended at certain intervals on the 911 Turbo 991 and variations for the 4wd system. For example, the dual fluid replacement for the front differential is split across two different service intervals on the 991 cars. Also, Porsche recommends the replacement of the PDCC reservoir, which contains a filter, every six years. We recommend the services of an expert Porsche shop for maintenance of your Porsche 911 Turbo.

Porsche 911 Turbo Recommended Maintenance Intervals – 991

To keep your Porsche 911 Turbo 991 healthy, we recommend you inspect the car and change the engine oil and filter annually or every 10K miles. The original Porsche 911 Turbo maintenance schedule for the 991 cars called for a minor service at 20K or two years and a spark plug change at 30K or at the 4 year interval. Additional maintenance items are also required at the six year and 12 year interval, as shown below. In addition, we recommend a PDK clutch fluid replacement at 40K miles.

Many people become confused by Porsche maintenance schedules. The intervals and maintenance items are cumulative –  so for clarity, a 4 year service includes all the maintenance items recommended at the 4 year interval, plus all maintenance items from the 2 year and annual maintenance interval as well.

Safety and Maintenance Inspection

Every annual service of your 911 Turbo should include a rigorous safety and maintenance inspection. It’s essential this is carried out by a skilled Porsche technician who knows the likely wear characteristics of your Porsche and can identify issues of concern at an early stage. A thorough inspection should reveal maintenance items that have been influenced by local environmental conditions.

Some maintenance items are described as “lifetime,” such as coolant, for example. It’s important during the inspection to discover the health of these “lifetime” items. If you need cold weather protection from your coolant, you’ll find the “lifetime” is considerably shorter than you might expect! Identifying mechanical problems at an early stage allows planning and budgeting for the necessary work.

Maintenance for HPDE and Track Driving

If you plan to take your Porsche 911 Turbo to the track for some fun, there are different maintenance considerations to make. In general, track driving will speed up the requirements for maintenance and the replacement of service items. Most track day companies, groups and the PCA HPDE, will require a safety inspection be completed by a Porsche repair shop. However,  you should view the safety inspection as the minimum requirement for having a safe day out at the track with your Porsche.

If you’re pottering around in the novice group at a track day, most of the standard maintenance service items on your Porsche are up to the job. Once you progress to more spirited driving in the advanced run groups, it’s quite easy to quickly exceed the performance of those standard service items, especially if you are running multiple track days in a season.

At this stage, it’s extremely important not only to complete a safety inspection, but also to radically speed up maintenance. For example, a brake fluid flush and oil change before each event is a sensible approach. Likewise, a spark plug change after two events will keep your engine running healthy under track conditions.

There are upgrades to standard maintenance items for the 991 Turbo cars that can help prevent over-driving. For example, Castrol SRF brake fluid will be far more durable than the standard brake fluid. There are better engine oil recommendations for the track versus the standard Mobil 1 factory refill. As your driving progresses, it’s also worth considering different brakes and tires. A specialist Porsche shop with track experience, can better help you understand the increased maintenance requirements for your car.

  • If you're preparing your Porsche for a track day or HPDE event here are some handy maintenance or service recomendations.
