If you're doing an oil change you can jack up the rear suspension mounting point shown in his diagram 2 and place jacks on the rear. You don't need to have the vehicle jack up in all four points for this. A briefing on how to safely jack up your vehicle isn't enough. Make sure you practice safety precautions and have several supports while underneath the car. Don't rely on just jack stands or a jack to support your vehicle.

I’ve had some minor disagreements with recommendations made in the 101 Projects book (based, necessarily, on research I’ve done on the matter in question—I’ve not been wrenching on cars since I was a kid like some of the folks on this board), but I’m not sure I agree with your assessment regarding the front jacking point Wayne uses. The one with the yellow arrow.

This guy seems to like it, and it’s pretty clear he’s done lots of work on his Boxster (up to and including IMS bearing replacement), much of it requiring jacking:

I would definitely go along with his suggestion that a hockey puck (or similar) be utilized if that spot is used for jacking. Aside from that, it seems he’s used that location repeatedly without problems.
