991 annual oil change ?
Discussion
Just wondering what the view was on changing the oil annually on a 991 C4S regardless of millage, I won't be covering 20k per year in mine, but do not think waiting for two years or 20k miles is necessary good for the engine, so I am considering having the oil changed after 12 months.
Am I wasting my money?
What should I be paying for just an oil change and should I go to a independant rather than my OPC who just quoted me £480!! for an oil change......

Do you really think a global manufacturer of cars will advise you to change the oil every 20,000 miles or 2 years if it felt the oil really needed changing at 1 year when it has absolutely no cost to them whatsoever.
To be fair, I think Porsche would tell you to service the car in such a way that they get more money overall. If:
1) a 2 year / 20K mile service interval attracts a few percent more punters to buy a new car than would have on a 1 year / 10 k mile interval
and
2) this makes more money than they would have on the extra servicing (note that a 991 minor service is almost double the cost of a 996 minor service that happens twice as frequently )
and
3) only minimal added risk of engine problems outside of their warranty period
....it'll likely make them more money than a 1 year / 12k mile service interval
Personally, when my BGTS arrives, it'll be getting an oil change after the running in period and at least once a year whether a service is due or not until someone can show me some evidence that changing the oil will cause problems

The service interval is tested and approved by Porsche engineers.
Oil technology has come a long way since we were kids and we serviced cars every 6,000 or 10,000 miles.
It seems some myths live on.
Changing the oil after run in makes sense for those planning to keep their cars for a long period.The service interval is tested and approved by Porsche engineers.

Reminds me of the time I was a BL mechanic many many moons ago , the Mini needed servicing every 6000 miles , the Metro came out and needed servicing every 12000 miles.The service interval is tested and approved by Porsche engineers.

Both cars where the same engine , same amount of oil and same oil filter.
You should have seen some of the metal attached to the magnetic sump plug every time you drained the oil .
My understanding is the 2 year / 20k service interval was more about Porsche being able to tick the 'environmental' box, so to speak.
There is also scientific evidence to prove that oil quality breaks down over time with pollutants & hence doesn't offer the same protection.
An annual oil change in my experience is a complete no brainer regardless of how many miles the car has / hasn't done. For the sake of £80 of oil & an hours labour, it's an irrelevant cost in comparison to the car.
Also, I'm pretty sure that it would help upon resale by proving your a diligent owner.
My 987 Boxster S has had an annual oil change or service since new, it was one of the things that attracted me to buying this particular car against other Boxsters which had only seen the inside of a garage every 2 years.

Likewise, show me some evidence that after 1 year and 10,000 miles the oil is less likely to protect the engine than new oil.Most 991/981 owners from new probably don't have the faintest or inkling just how hard these cars can go and don't use a fraction of the performance. Most of the cars won't ever see a track or ever be driven hard in any meaningful way. In that context, a 2 year service interval is probably not the end the world. But you'd struggle to persuade me that after collecting my BGTS next month, if I ran it in, then drove the tits off it round Europe (as I plan to do) for a week or so, then completed a further 17k or so miles in the next 24 months including potentially up to 10 track days, that doing all that on one lot of oil is not going to impact the long term reliability of the engine.
I'm not saying I definitely will do that and clearly I don't think the engine would blow up if I did, but as someone else has said, for the sake of £200 or so (and the opportunity to have a nice courtesy car while they're at it), it does seem like a no brainer.

I think it depends on how one uses a car.
An example, not a 991, would be my old E36 M3. I changed the oil every 3,000 miles in my ownership as the car had heavy heat cycles and quite hard use when warm (I lived in Jersey and it spent much of its time commuting; the oil also got much hotter than it would on a good run as the il cooler never had enough air flow).
This was at half the adaptive service indicator's indicated change interval and I was using decent oil; it probably contained myrrh, etc. Seeing the oil that came out when I changed it, I never doubted the change intervals that I ran the car to.
If one is planning on keeping a car, a bit of oil is hardly the most expensive thing in the world and I believe newer is better and the peace of mind it gives (and a chance to look over the car) is worth it.
