I watched my oil get changed at the dealership since I know all the mechanics.
There is a small plastic spout that he inserted after unscrewing the small cap off the end of the filter. He then inserted this spout and it drained the oil from the filter before he unscrewed it to remove the element.
A hell of a lot cleaner than the old Chevy's. I also like the fact that I can pull the pleats apart and see the flakes of metal from oil change to oil change.
The first change looked a bit scary but the other two changes looked real good.
Just my 2 cents
