To maintain your vehicle's health, it is important to change your engine oil and filter regularly. Porsche recommends changing the engine oil and filter every 1 year or 10,000 miles. However, we recommend a replacing your engine oil every 5,000 miles if you want to keep your engine healthy for years to come.
