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.
