991 Carrera maintenance intervalsWhat’s Included at the 991 Service Interval

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

maintenance service questions on Porsche 911 991 CarreraLifetime Maintenance Items

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.

Original 991 Factory Maintenance Schedule

Maintenance for HPDE or track day driving

Maintenance for HPDE and Track Driving

If you plan to take your Porsche 911 Carrera 991 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.

When to Service Your Porsche 911 for the Track

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.

Maintenance Upgrade Recommendations for Race Track Driving

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 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.
