I'm getting ready for my first oil change on my 958 TT. I recently ordered the Durametric (enthusiast version) so i can do it all, start to finish, and not rely on my dealer.

Thanks again for the informative/detailed post!

Removing the Filter:

By now the sump has probably drained sufficiently so you can button it up with a new washer on the drain plug. Recommended torque is 50nm or 37ftlbs. Sump and plug are both aluminum: DON'T OVERTIGHTEN. Move your drain pan under the filter housing. The filter cap (and filter) are the exact same ones used on the 997.2 Carrera. A 36mm 6 or 12 point socket is required to remove it. FWIW, this is a change from the earlier V8 which required a 76mm 14 sided cap wrench. Remove the cap (Picture 9), allow the oil to drain and remove the filter element (Picture 10). Picture 11 shows how to remove the old filter ring gasket from the cap. Note the groove in the cap where the ring gasket resides. Wipe down the filter cap, lightly oil the new gasket with fresh oil, and slip it over the cap into place.



Add Oil:

You'll want to do this before reinstalling the engine trays, so you can start the car and check for leaks. The stated capacity of the engine and filter is 9.5 quarts, however it is critical that you don't overfill as damage to the engine or catalytic converters can result. Depending on how long and thoroughly you let the engine drain and whether the car is level, a full 9.5 quarts may not have come out. For that reason, I always fill initially to something less than capacity, but enough so that at worst I will be above the minimum level when I start the car. In this case I added about 8.75 quarts. After starting the car and checking for leaks I brought the engine up to temperature to get a reading on the oil level gauge. It read "Oil Level OK" but it was 1 bar low. Each segment of the gauge is supposedly equal to .26 of a quart, but since the point at which the next bar is illuminated is unknown (to me at least) it's best to proceed slowly. Rechecking after each add, I added a couple of tenths of a quart, then 2 more tenths and the guage was at full (Picture 13). Total oil added was about 9.25 quarts. The thing to remember is, don't just dump in 9.5 quarts; sneak up on it and you won't overfill.

Finishing Up:

Time to reinstall the engine trays in the reverse order you took them off. I didn't torque the screws, I just made sure they were snug without tightening them too much. The clips and screws on engine trays often don't fit well on some cars but these all lined up perfectly. The car comes down off the jack stands or whatever and it's ready to go. BTW, if your "service due" indicator has come on, you will need to have your Porsche dealer reset it. Mine does it as a courtesy.

For me, the savings of a few hundred dollars isn't the biggest attraction of doing this job myself. There's not much shade tree maintenance that can be done on cars any more without specialized equipment or expertise, but an oil change can still be one of them. Spending quality time under the hood may not be everyone's cup of tea, but for some reason, it's especially rewarding when that hood is on a Porsche, and this service on the 958 Cayenne V8 is pretty easy. The money savings is icing on the cake.
