During 20+ years of automobile ownership, I've never bothered to learn to change the engine oil on my own car. Thanks to the egregious pricing of routine maintenance by the Porsche dealerships, I decided to collect the necessary tools and the knowledge on the web. Youtube videos by myturbodiesel.com was one of the most informative.

Here is a comprehensive list of tools and parts necessary to execute the job:

1. Porsche C30 compliant synthetic oil (2 cases, or 7 quarts)
2. Oil Filter
3. Oil Extractor
4. 32mm Socket
5. 3/8 inch drive ratchet
6. Funnel
7. Rubber gloves
8. Hose remover or Screw driver (to release the filter canister O-ring)
9. Two empty gallon milk jugs
10. VW Dip stick (optional)
11. Durametic (optional)
12. Ad Blue (optional)

One observation worth mentioning is that the oil extractor tube goes down rather too easily. Be sure not to push too much it down. The VW dipstick (which is too long by several inches to provide an accurate reading) is a good guide for how far one should go.

I was able to extract and refill ~7 quarts. Cayenne's electronic oil level meter doesn't provide an immediate read of the oil level upon post-refill engine start. A VW dipstick comes in handy to keep the electronics honest.

Finally, we have curb-side recycling of used motor oil and filter in our area. This is a no-brainer DIY job given the the effort and pain involved in booking an service appointment and loaner from the local stealership. Total start-up cost is reasonable and the recurring cost is a fraction of what they would charge. And most importantly, you have the confidence of knowing that the job was done right.

Which extractor did you buy? I thought I'd save the extra work of hand pumping for vacuum, plus I had a brand new 170 psi compressor in the shop. But the one I bought starts sucking air before I even get 6 quarts out. I got the impression that the tubes were hitting some sort of baffle. Hadda go up on ramps to get the last 2 quarts out from beneath the car.

And given that the engine oil capacity is spec'd at 7.7 quarts (7.3 liters), it would seem you either your oil level was low to start - or you left some in the pan like me. Last oil change I put in a full 8 quarts, so I decided to see how much was was still in the "empty" containers. When allowed to drain completely, the stuff left inside 8 bottles totaled 0.3 quarts - pretty much confirming the 7.7 quart capacity.

I used the Mityvac 7201 Fluid Evacuator Plus (http://www.amazon.com/dp/B0002SR7TC/?tag=jisge-20). Its capacity is large enough to perform a Cayenne Diesel oil change in a single shot and has a cool reversible switch to dispense the dirty oil into an external empty container while the engine is being refilled with clean oil.

I don't worry about the residual dirty oil left behind in the engine. Post-refill, the electronic oil level indicator reports one incremental level of oil level higher than where it started which was at dead middle of the four increments. From what I gather, the art of oil refilling is like the game of Price Is Right, get close as you can, but never over. :)

I do. The contaminates left in the pan are in your fresh oil within seconds of starting the engine. But it's your car. The other advantage to making sure it ALL comes out, it to avoid the electronic dipstick issue. Once you are positive that all the old oil is out, you can safely pour 8 new quarts of fresh oil back in. Subtracting the 0.3 quarts of oil that clings to the inside of 8 otherwise empty quart bottles, the actual amount you put in is the 7.7 quarts needed to get the oil level correct from the git-go.

A quick update on this thread after performing a second oil change on the Cayenne Diesel at 10,000 miles. Remember to use the thicker of the two flexible hoses of the extractor.

Do any of you open up your hood, then close it, then start the motor, then shut it off for 2 minutes, then read what your oil level is at, immediately before doing an oil change? That might have an effect as to how much oil you should expect to remove.

2013 Touareg TDI's in the 1st 10 k miles can be a bit of an oil burner... I do not know if this applies also to the Cayenne Diesel, but it is the same Gen II motor family.

A bit of the run down on the motor history...

Checking in again at 24k miles on a 2014 Porsche Diesel Cayenne. Two more DIY maintenance items to report - cabin filter change and replenishment of DEF

Ad Blue Diesel Emissions Fluid
Cabin Filter

Relatively trouble-free ownership experience so far during the past ~2 years of ownership. One visit to the stealership at ~21k miles due to engine-check light.

I followed all of the prescribed procedures for the oil change in my '13 Cayenne Diesel.
The oil level on the VW dipstick shows full, or a little over filled but the service reminder on the dash says "minimal oil level has been reached"
Any advice?
Thanks,
Pete

Pete, I've gone thru similar situation where the VW dipstick and the electronic oil level sensor disagrees. I usually end up supplementing 1/4 to 1/2 quart of oil to make the dash warning go away. I hope that helps.

Completed oil change in 2013 Cayenne Diesel.
Filled with 8 qts. Reading on the VW dipstick (as recommended above) shows over filled.
Dashboard Oil level indicator suggests "Minimum Oil Level Has been Reached"
I don't want to add any more and cause a bigger "overfilled" problem.
Thoughts?
Thanks, Pete

My VW dipstick measures 24.75" inches overall.
22 inches from the bottom of the stick to the flange that will be inserted. (not including the handle)
Is it too long? Showing overfilled.

Are u guys changing your oil every 5k miles or 10k miles? Curious as all of the VW TDI's I've owned all day to change oil at 10k mile intervals. And I believe the Audi Q5-7 3.0 diesels are at 10k miles. Curious why the same motor in the Porsche has to be changed at 5k miles? Thanks

What does your manual say?

I'm pretty confident that the manual says oil service at 5k miles. Just seems strange as the same motor in the Q5 and 7 gets serviced at 10k miles.

Hmmmm....not sure how the exact same motor and drivetrain would be any harder in one vehicle to the other. Only difference I could see if the tune in the Porsche is significantly higher output than the same motor and drivetrain in the Audi Q5-7.
