Threw this together for my 1200-mile break-in oil change performed last night. I recommend wearing rawhide gloves, as the oil is uncomfortably hot at operating temperature! Also, the oil drain plug is pretty tight coming from Leipzig--we can thank the robots for that. The whole process took about half an hour.
