Good point Meir, while I was overhauling my suspension for 3 weeks I had the oil drainplug out. After the 1st day of draining oil I removed the drain pan. Overnight about 1/4 of a quart drained out on the floor, after cleaning up the oil I placed a cardboard box under the oil drain. Oil continued to drip for 2 weeks & I am sure I drained close to a quart after the first day. When you have the sump plate off it's obvious Porsche designed the drain bung for ground clearance (996) not oil drainage.
When I reassemble a M96 engine I use about 1.5 qt. of new oil in addition to assembly lube but almost half the oil drips out of the engine.
