It used to take me an hour now about 45 minutes enjoying the process.

It is very easy, removing the ABS slid plate and side pieces, drain the sump (there is a second drain plug up 4 or so inches higher) this is a design feature to prevent oil starvation when the Cayenne is being driven at extreme angles off road. Changing you Cayenne oil is like anything, it becomes easier and easier the more time done. And definitely change it at about 5500 miles or sooner due to ethanal in fuels as i have advised.
This advise came to me from the lead Tech at my local Porsche dealer who is a Cayenne expert. Great, great motor so change the oil frequently. Healthy Porsche motors still allow some fuel past the valves and into the oil supply. Ethanol can build up in the oil and "wash out the cylinder of its oil".
This is seen in Cayenne which have missed oil services and gone 15k miles or so without a change. You can smell fuel in your old oil when changing it.
