Got a question for our Porsche technician? Email us editorial@total911.com Dear Sir, I’ve owned my 2014 911 991 Carrera S for coming up to four years now. However, I’ve covered very little mileage – only approximately 2,500 miles in that time. Its next big service is due soon, but I’m wondering whether it really needs this major maintenance session and additional schedule items, because of the low mileage and it being garaged? What are your thoughts? Neil Gillingham
Hi Neil, it’s a great question and one that’s frequently mentioned by enthusiasts at point of service. The service intervals advised by Porsche are fairly clear and are dictated on either a time limit or mileage limit, whichever comes sooner. On the 991 generation, these are two years or 20,000 miles. Therefore even if that mileage limit isn’t hit, then the service items are still advised regardless of how far you’ve travelled.
I’m an advocate for the annual oil and filter servicing as an additional measure regardless of mileage, too. The reason is that moisture or condensation can enter the engine if it’s not used for extended periods of time during the colder weather, and this can reduce the oil’s protective qualities. A quick oil change can eliminate that, ensuring your 911 is in top condition whenever it is called upon.
It’s worth pointing out the majority of Porsche 911s rarely hit the mileage limit at point of service, but my best advice is to follow the schedules outlined by Porsche in any regard. It ensures that everything is as it should be, with all components checked and replaced as required.
Take the drive belt for example. This may have seen little mileage; however, over time the rubber can deteriorate, harden and in some cases perish. This can lead to squeaks, noises or, in the worst case, complete belt failure. It’s better to stay on top of that scenario rather than have it let you down and leave you stranded at the side of the road. Additionally, you’ll be surprised how dirty pollen filters can become even from little mileage.
Aside from the mechanical points of view, a full history at the correct schedules adds to the vehicle’s value and saleability if you decided to ever part with your car, so there are multiple benefits to following those service schedules. I hope this helps.
