Service Intervals for the 718 GTS 4.0
Porsche recommends a regular service schedule for the 718 GTS 4.0, with intervals based on either time or mileage, whichever comes first. Here’s a breakdown of the main service intervals:
Annual Maintenance or Every 10,000 Miles / 16,000 Kilometres
- Oil and Filter Change: One of the most important regular maintenance tasks for your GTS 4.0 is changing the engine oil and filter. This ensures the engine runs smoothly and reduces wear. While the car’s oil system is of high quality, regular changes help maintain its performance and longevity.
- Check Fluids: At each annual service, your Porsche technician will check key fluids, including brake fluid, coolant, and transmission fluid. These will be topped up or replaced if necessary to maintain optimal performance.
- Brake System Inspection: Brakes are critical on a performance car like the GTS 4.0. The brake pads, discs, and fluid will be inspected, and any signs of wear will be addressed.
- Tyre Check: Tyres are checked for wear and pressure. The GTS 4.0’s high-performance tyres need to be in good condition to ensure safe handling and optimum performance.
Every 2 Years or 20,000 Miles / 32,000 Kilometres
- Brake Fluid Replacement: Porsche recommends replacing the brake fluid every two years. This is an important task, as brake fluid absorbs moisture over time, which can affect braking performance.
- Air Filter Replacement: The air filter keeps dirt and debris from entering the engine. Over time, it can become clogged, reducing engine efficiency. Replacing the air filter ensures the engine gets the clean air it needs for optimal combustion. Consider swapping to the K&N Performance Replacement Air Filters here
- Pollen Filter: The cabin air filter (pollen filter) should also be changed every two years to maintain air quality inside the vehicle.
Every 4 Years or 40,000 Miles / 64,000 Kilometres
- Spark Plug Replacement: Spark plugs play a vital role in the engine’s ignition process. Over time, they can degrade, affecting fuel efficiency and engine performance. Replacing spark plugs every four years helps to maintain smooth engine operation.
- Drive Belt Inspection: The drive belt is essential for powering accessories like the alternator and air conditioning. It should be checked for signs of wear and replaced if necessary to avoid failures.
Every 6 Years or 60,000 Miles / 96,000 Kilometres
- Coolant Change: The coolant system is vital for maintaining the engine’s operating temperature. Over time, the coolant can lose its effectiveness. Changing the coolant at regular intervals ensures the engine stays within its ideal temperature range, even under heavy use.
- Brake Pad and Disc Inspection: Depending on driving habits and road conditions, brake pads and discs may need to be replaced. While Porsche’s high-performance braking systems are durable, they still need to be checked and replaced at intervals.
Special Considerations for the GTS 4.0
The GTS 4.0 is powered by a naturally aspirated 4.0-litre flat-six engine, which demands specific care and attention. Here are some considerations for maintaining your GTS 4.0:
- Engine Oil: The flat-six engine requires high-quality, synthetic oil. Always ensure that the oil used meets Porsche’s specifications. It’s also recommended to use Porsche-approved oils to maintain the engine’s performance.
- Exhaust System: The sports exhaust system on the GTS 4.0 is designed to give you that signature Porsche sound, but it can accumulate carbon deposits over time, especially if the car is used mainly for short trips or in city driving. A longer, more spirited drive can help burn off these deposits.
- Suspension: The GTS 4.0 comes with Porsche’s active suspension management (PASM), which allows you to adjust the car’s suspension for different driving conditions. Regular suspension checks ensure the system operates as designed, maintaining the car’s dynamic handling capabilities.
Other Maintenance Tips
- Battery Care: Regular checks of the battery are important, especially if you don’t drive the car frequently. Porsche recommends a battery inspection every 12 months. A well-maintained battery will prevent issues with starting the engine and ensure that all electrical systems function as intended.
- Transmission Fluid: While Porsche’s dual-clutch PDK transmission is low-maintenance, it’s still important to check the transmission fluid at the recommended intervals, particularly if the car is driven hard or used on the track.
Porsche Approved Service Centres
To ensure that your Porsche 718 GTS 4.0 is properly maintained, it’s advisable to have it serviced at a Porsche-approved service centre. These specialists are trained to work specifically on Porsche models and have access to the latest tools, technology, and genuine Porsche parts. Using a non-approved service centre could lead to issues with the car’s performance, warranty, and resale value.
Conclusion
Maintaining your Porsche 718 GTS 4.0 is crucial for ensuring it stays in peak condition, performs as expected, and holds its value. Regular servicing according to Porsche’s recommended intervals—every 10,000 miles or annually, every 20,000 miles or every two years, and further checks at longer intervals—will help keep the car running smoothly. By following these service schedules and addressing any issues promptly, you can enjoy the thrill of owning a Porsche 718 GTS 4.0 for years to come.
