Bought the suction device from Griot's garage, warmed up the 360CH, put the plastic tube down the dipstick tube, gave it a couple of pumps and voila- 1 quart of oil came out. Apparently the dipstick has no straight shot to the sump, so that's all I can get out. Called my mechanic, and conventional oil change requires removal of entire underbody tray just to get at the drain plugs. The tray has about a million fasteners, any of which can come loose if not reinstalled properly by an amateur like me (which would totally disrupt ground effects at 140 mph and create a very interesting time for me). There is NOTHING that can be done to a 360 by a DIYer. It's getting very frustrating not being able to do anything but write checks. I need a simpler car.
