Engine oil is vital to your car’s engine. It’s primary function is to protect internal moving parts by providing lubrication to reduce friction and metal on metal contact. Over time the oil loses its critical properties, so regular replacement of the oil and filter are essential to maintaining your vehicle’s engine.
Porsche recommends changing the engine oil and filter every 1 year or 10,000 miles. However, we recommend replacing your engine oil every 5,000 miles if you want to keep your engine healthy for years to come. While it may be intimidating to work on your Porsche, changing the oil and filter isn’t much different than on other vehicles. This is a great entry-level maintenance procedure that you can perform yourself and save yourself money on year after year.

Step 1: Prepare your vehicle and work area.
- Drive the car for 5 minutes to warm up the engine. This will help the engine oil drain more easily.
- Position vehicle on a flat surface.
- Gather required tools and parts
- Put on gloves and eye protection.
- Open the hood and remove the oil fill cap, which will help the engine oil flow more easily.
Step 2: Raise the front of your vehicle to give yourself extra clearance.
- If you have air suspension, simply raise your car to the highest ride height.
- If not, raise the front of vehicle via vehicle ramps or jack stands.
- Be sure to use wheel chocks and the parking brake to prevent your car from rolling.
- To get jack stands on the front jack points, jack the vehicle by the center cross member as shown in the photos.
- To get jack stands on the rear jack points, jack the vehicle up be the rear cross member which is just ahead of the rear differential and in between the exhaust pipes.
- NEVER rely on a jack to support your vehicle.
- Note: If you have air suspension and decided to jack up the car, you will need to lock the air suspension by starting the car and holding the air suspension button up for 10 seconds. You will see an indicator pop up on your gauge cluster.
Step 3: Remove the underbody trays.
- Remove front underbody trays, which are held on by several T25 Torx screws and 10mm bolts.
- Also remove the panel covering the mid section of the vehicle, which is held on by 10mm bolts.
Step 4: Remove the oil drain plugs and drain the engine oil.
- This Cayenne model has two engine oil drain plugs.
- Remove the main oil drain plug using an 8mm hex bit socket and place a drain pan underneath.
- Next, remove the second oil drain plug using an 8mm hex bit socket and place a drain pan underneath.
- Be sure not to let the oil drain plugs fall into the drain pan.
- Allow the engine oil to drain for 15 minutes.
Step 5: Remove the engine oil filter cap.
- While the oil is draining, use a 74mm / 14 flute oil filter socket to remove the oil filter cap, which is located underneath the engine and forward of the oil drain pan.
- Be sure to place a small oil drain pan underneath to catch any dripping oil.
Step 6: Replace the engine oil filter.
- Remove the old engine oil filter.
- Replace the oil filter cap o-ring seal with a brand new one, which should have been included with the new engine oil filter.
- Insert the new oil filter into the oil filter housing cap.
- Lightly coat the o-ring seal on the oil filter housing cap with fresh oil.
- Re-install the new oil filter and cap and torque it to 19 ft-lbs.
Step 7: Re-install the oil drain plugs.
- After allowing the oil to drain for 15 minutes, screw in the oil drain plugs along with brand new crush washers by hand initially.
- Torque it the drain plugs to 37 ft-lbs.
- Note: Be sure to use brand new crush washers or you engine oil may leak. If the current oil drain plugs are in good condition, you can re-use them. If not, replace them.
Step 8: Add new engine oil.
- Now it’s time to add engine oil.
- The engine oil capacity is ~9 quarts, but start by adding 8 quarts to prevent from overfilling.
- Ensure there are no leaks from underneath the vehicle.
Step 9: Re-install the underbody panels and lower the car back down.
Step 10: Top off the engine oil as needed.
- Take the car for a short drive and get the engine oil up to operating temperature.
- Park your car, turn off the engine, and allow the car to sit for 5 minutes.
- Open the hood and check the engine oil level using the dipstick.
- To do this, pull the dipstick out and wipe the tip dry with a clean paper towel.
- Reinsert the dipstick all the way, remove it, and check the oil level.
- The difference between the “min” and “max” levels is ~1.5 quarts.
- If necessary, add oil in 0.25 quart increments and recheck the oil level until the engine oil level is between the minimum and maximum levels.
Step 11: Reset the service indicator.
- To resent your service indicator, you will need a tool like the following: ↗️iCarSoft POR II Tool.
- Check out the video from the following YouTube channel for instructions.
Step 12: Clean up your work area.
- Put your used engine oil in a container and take to your nearest auto parts store to recycle during your next trip.
- Clean up your work area and put up your tools. You’re all done!

Where is the second drin plug fir 2006 Cayenne S?
J says:
Just a little bit further towards the back. Sits a little bit higher up. Drain the 2nd plug after the first one is completely done. This way there will be significantly less oil coming out.
