991 gts in RPM showroom

The Porsche 991 model series was launched at the end of 2011 and ran through until 2019. Services on your Porsche 991 are due every 2 years or 20,000 miles. These alternate between a ‘Minor’ and  ‘Major’ service. The most notable difference between the two being the spark plug change on a major. The Porsche 991 was face-lifted in 2016 where one of the biggest changes was the engine being changed from 3.8 naturally aspirated to a 3.0 twin turbo.

Whilst Porsche 991 servicing is recommended every 2 years or 20,000 miles, as the vehicle’s age it is worth being pragmatic that this is quite a long time and mileage interval for oil to be in your engine. We would recommend an annual oil change in order to ensure your Porsche 991 is kept in the best possible health. Annual Porsche 991 services also benefit from a safety assessment, as a professional technician can inspect the car to ensure that it is in the best condition. Porsche 991 servicing is carried out at RPM Technik using Mobil1 oils and genuine Porsche parts.
