Thanks for your responses.
I've considered the topsider, but I suppose I'm a bit old school and I like getting the dregs off the bottom of the pan by pulling th plug. I've not yet removed the plastic cover, but is it painfully obvious once this is off, where the drain plug is? Anyone know what size head on the plug?
Regarding using ramps, does the attendant angle of the vehicle on the incline help or hinder a thorough draining of the oil? Is a better drain achieved when the car is on a level surface?
