I bit the bullet and bought a Portaquick 12V oil change pump from West Marine. I put the back of the car up onto small ramps, ran the engine for about 5mins, let the car sit for 10-15mins, then I let the Portaquick suck away. It does a nice quick job and this time I believe I got most, if not all, of the old oil outta the pan. I took the car off the ramps and onto level ground. I put 7.6 liters (two of the gallon Delo 400 bottles) into the car and checked the stick. I was surprised to see it registered maximum. The owner's manual calls for 8 liters with oil filter change, which was done. Comments or suggestions?
