How often do you change your oil?
#46
I agree with this. In general cars rarely fail due to not changing the oil more frequently than the manufacturer recommends. Lots of other things deserve greater emphasis from the standpoint of overall car maintenance. To drive a Generation 1 Cayenne to 250K+ miles, I'd first replace the plastic coolant pipes, make sure the brake fluid is replaced every 2 years, keep replacing the tires and brakes per schedule, check the coils, check the hoses, etc. In other words, I'd do the comprehensive car maintenance when the time/mileage comes. I would not lose sleep over the oil or engine failure.

Follow the schedule in the owner's manual, or change more often if that is what you like to do. Do whatever helps you sleep at night, but don't go beyond the factory specified interval...
We change far more frequently in our own cars as we subscribe to the the theory that oil is cheap and engines are expensive.... Cayenne TT we change every 5-6K miles, Cayman S the same, or after every DE (which ever comes first!), and the 996 race car gets changed after every second event.
YMMV

Actually Jake Raby of Aircooled Technology has a device that monitors the oil for indication of impending bearing failure (don't need to hope for a well timed oil change). This is one of his sites but not sure it's the one with the 996 parts. I'll search for more detail.

Ah, found it, it's called the IMS Guardian, see:

I guess the next step would be to build a micro-GCMS into the PCM.. with perhaps a viscosity flowmeter someplace in the oil path.. (If anyone wants to know what a GCMS is - Google is your friend..)

Drifting
I'm on a harsh environment regime here in the Middle East, 20,000 km (12,500 mi) on the CTT and 15,000 km (9,3750 mi) on the GTS.
Doesn't seem to have any ill effects, oil still looks pretty clean before changing.

Very cool technology.. it collects metal particles (I assume just ferris/magnetic ones) and measures the amount of them.
As for seeing the oil in our 2011 and beyonds, unless we see it when they take out the drain plug, we won't see our oil - no dipsticks!

OK Say my oil IS good for 10K and the engine doesnt mind it like the manual says. What about the filter? You have to admit, the filters on these things are ****ty little paper elements. I replace my filter every oil change anyway, but 10K seems like quite a bit for those crappy little things. No?
FWIW, I installed LN Engineering's 996 Spin-on Filter adapter on my Cayenne (the part numbers matched up, so I went for it).
I DO NOT recommend that anyone else does this as I have NO actual data to support this decision (it will also likely VOID any warranty). To my knowledge, I am the only one to try this.
I can tell you that I have put about 10k miles and a couple of oil changes on it without losing a drop, and now I can use high-flow metal filters like Mobil-1 and K&N.
Just thought you might find it interesting...

I like the paper filters. Aside from being better environmentally they're much easier to cut apart for inspection when you remove them. Each to their own though.

Holy thread revival.
Here's one for you. My good friend who is a collector of twin rotor helicopters decided to see how long a car would run if you never changed the oil. He bought a new ford escort wagon in 1993. He drove it for 130,000+ miles and never, changed the oil. He never changed the filter. He would add oil if and when the oil light came on. The car ran perfectly. Didn't burn oil, no strange noises, nothing.
I ran my Merkur XR4Ti for over 100,000 miles on top of the 50,000 that were on it when I bought it by doing oil changes at 25,000. Never had engine problems even at 150,000.
I currently do the same thing for my work trucks and equipment Fords,Chevys, Sterling, Freightliner, Caterpillar, Deere. We just do an oil analysis and change the filter once per year on them.

I'd like to share with you guys what i saw underneath the car (Cayenne 2008 v6 3.6) before doing the oil change job, will try to drain some oil out first. Do you guys think we can first unscrew the middle round screw on the filter to drain some oil before taking out the cap? Anyone know the OEM part for the filter? Thanks!

I have a 235,000 mile '06 CTTS. I've changed the oil every 10,000 miles. It has always consumed a LOT of oil, so it gets lots of quarts in between.
Until it consumes a quart every fillup, I'll just continue on, as is. The car is worth nada at the moment, so, what the heck.
