Does everyone do the full annual service (1x/year or 10k mile service)? I typically put about 10k miles on my 991/year and replace the oil every 5k miles. Is the full annual service necessary or should I only replace the oil, filters, etc. (and brake fluid every 2 years)? A large portion of the service seems to be checking the lights, road testing, etc.

Also, the brake fluid should be replace at the 2yr mark (from the date of production), correct?

Thanks,
DJ

Yes, the brake fluid is based on time. Two year cycles is what's needed for that.

I wonder if the 2 year cycle for brake fluid replacement is really necessary. Does anyone think it can be extended to 3 or even 4 years if you drive less than 8K miles a year and don't drive the car really really crazy? I can't remember the last time I replaced brake fluid in my other car.

Depends on factors, but if you track or drive aggressively, then it's a good idea, though you can honestly get away with a longer interval--hell, on my other cars and motorcycles, I've gotten away with not changing brake fluid for >3 yrs; first thing you'd notice would be degradation of brake performance, with softer brake pedal and possibly more force required to activate your ABS.

If you don't plan on selling your car I'd say do as you please. If you do plan on selling, I'd stick with the factory intervals. I wouldn't consider buying a used 991 if the person hasn't kept up on factory maintenance. In fact, I'm not buying if they stretch their oil changes out to 10k.

On my 2013 C4 CPO I do the 5000 mile/6 month oil change and have the dealer do the 10000 mile/one year change/service.

The 'full' annual service is just an oil change, and only if 10,000 miles isn't reached sooner.

Since todays' cars require minimal service, some dealers try to convince owners that there are other "services" that should be performed every year. The Porsche Owners Manual clearly specify what services must be performed on yearly / mileage intervals . The only service which must be performed annually is an oil change, and if you shop around you should find a dealer who is willing to do an oil change for well under $300. On the other hand I've heard of some dealers who charge $500 for an "annual service". The other services are "minor service" performed in year two and the "major service" in year four.

Brake fluid loses it potency over time as it attracts moisture. This is expressed as a function of temperature performance. As an example, lets say a particular brake fluid is rated to 500 degrees use when fresh out of the can. In two years, that brake fluid may not only tolerate 400 degrees due to the moisture. What does that mean to you as a driver? If you are at a track day, or very aggressive canyon racing and your brake temps exceed the temperature the fluid can work at, the fluid boils and your brakes go out...done...toast....no pedal. Its a bad place to be. So track rats change frequently. Have an old pickup truck that only makes runs to Home Depot then you probably are not going to put a lot of heat in the brakes, see how it works?

Sorry my friend, that's not how it works. Brake fluid either works - or it doesn't. Now if you leave it in there FOREVER it will eventually collect so much moisture that your internal brake parts will rust, primarily the caliper pucks. So, change it on a schedule or you can even use these this little device which is quite handy. And its only $ 20.

I'm not willing to find out. I have it flushed every two years. It's only about $250 at the dealership. I'm willing to spend that. Just had mine done last month, a little early in the schedule, because I'd rather not deal with this in the Spring of 2016 after winter hibernation, I'd rather be driving the car when the weather breaks.

I flush brake fluid every 2 years. It costs $15 and takes 30 minutes.

I was told my two year service was $875 and I could wait on the $250 break fluid replacement. I will be going Indy at this point. The said $350 with the brake fluid change.

I normally do the dealer but - - - really.

LexVan

What's included in the $875 price?

Oil change about $300
Brakes about $250
Both cabin filters about $150

That's only about $700.

What's the other $175 for????

LexVan

Makes no sense.

You can remove & replace 4 wheels, flush the brakes, clean-up and put away in 30 minutes??

OE fluid is $28

Motul RBF660 is $30

Motul 600 is $20
