Driving my T 10K/yr so far. Do filters and an intermediate 5K oil/filter change myself in addition to yearly dealer visit. Dealer has been good to me in discretionary situations.

You can also just do it from the carfax website on a PC or MAC. You will need to create a login and add your vehicle

CSK 911 C4S

I perform maintenance by miles only.

And there's a bunch of them.

YOLO

wait you mean you don't leave your car in your garage and never drive it?! blasphemy!

I don't follow their schedule explicitly. Various reasons. But at the end of the day I will always do right by the car and apply years of experience in the restoration and service trades in addition to considering the service manual.

Certain things go bad with age. Others frankly don't and taking the car apart for service needlessly and throwing away good parts and fluids is not fun when you have a few toys that see low mileage use.

Porsche's service model still relies on mileage and/or time based service for everything. This is flawed when applied across the board.

For those lucky enough to drive >10K a year then obviously I would get the oil done. My 911 will get less than 4k in this the first year I have it. I will do the oil annually as its the least I can do.

I perform the services per the mileage/time intervals in the manual. When you compare the cost of the services to the purchase price of the car its not significant. Also, if you plan to sell the car privately having the service records will be a selling point.

If you follow the sched and keep records that you did, it removes an excuse that Porsche can try to use against you to weasel out of warranty work.

Conductivity meters make assumptions about the boiling temp of the fluid. The problem is brake fluid conductivity varies widely based on brand, DOT, et al. The only accurate tester is one that actually heats the fluid to boiling point and measures that temp. They exist but they are ten times the price of your typical tester from your local auto store.

But do your entries in myCARFAX show up when someone else runs an actual CARFAX report? Has anyone confirmed this, and if not, is there someone on the forum with access to CARFAX reports that can test this with LexVan's VIN?

It's a mixed bag when recommendation is for 10k miles before the first oil change. And when the manufacturer and dealerships use Mobil 0-40. That said, I would do most of the manufacturer schedules despite mileage. Ideally performed by a dedicated and experienced Porsche tuner over the dealership. There is no harm in skipping dealer services if performed and documented by a competent independent mechanic.

I have a 2017 911 Cabriolet. Got the oil changed last year at 18,000 and did the 20,000 mile service while I was at it. A year later I have just under 22,000 miles (not much driving during Covid!) and was surprised to see the "Oil Change" warning come on. Spoke to my dealer who informed me that time plays as much of a part as mileage. He also suggested I get the three year service, which includes the spark plug changing, for a total of $1,600! So my questions for you much more educated Porsche owners are the following: 1) Is any of this necessary when I just got the 20,000 mile service less than 4,000 miles ago? 2) What happens if I don't do it? Do I void my warranty? 3) Can I get some or all of this done at a reputable Porsche mechanic rather than a dealer or might that also put the warranty in jeopardy? Thanks in advance for your sage advice!

Same car with 8k miles and have had the ADD oil light come on once but never "Oil Change" warning.

Spark plugs at 22k?

How old is your car? Perhaps the dealer is recommending the 4-year service based on time. Given your situation, I would do a 3-year oil change at the dealer and do the 4-yer maintenance next year. Should not affect the warranty. I have seen folks with CPO deferring 4-year service by a year due to low mileage. In my case, I go by time since I drive around 5-6K miles per year.

The plugs on a 991.2 are far from easy and the recommended interval is 3 years. I was able to do the plugs on my 997.2 without too much difficulty, however I am still staring at the ones on my 991.2 and wondering if and how I am going to get the Turbos off. I do plan on doing it myself at some point. Maybe the heat cycles of a turbocharge car accelerate the galvanic action of the plugs and the heads. My instinct tells me this recommended interval is too conservative. I am sure it is a very expensive trip to the dealer to have it done.

you guys know the plug threads are coated right
