Check your sump sound dampener shroud
If you are draining the sump the traditional way via the sump plug, be aware that oil migration inside the plastic sound-dampening shroud below the pan is significant and gets absorbed by the foam inside the shroud. If left that way, the absorbed oil will begin to degrade the foam and eventually affect its sound-damping ability. Not the end of the world, but unacceptable for us anal types
When changing the oil for the first time @ 10K on my new stop-sale GSW, with a previous oil change by the dealer @ 300 miles (for stop-sale prep), I removed the shroud to find about a 1/3 of the molded foam had absorbed quite a bit of oil and it took a lot of wicking/sponging with a ton of shop towels to remove the vast majority of it.
Removing the shroud is a snap; pry the 4 plastic round-head pins down slightly from the 4 T-head shroud retainer rivets, then pull the pins the rest of the way out with pliers. Now pry the T-head rivets down until they drop down freely. Carefully pull the shroud down (w/ retainer rivets still attached or removed), finessing the molded foam underneath the shroud so that it doesn't stay attached to the pan and tear.
This takes so little extra time to do when changing the oil, I recommend doing it at least once just to see how much oil has been absorbed from previous oil changes. But once you go through the wicking/sponging procedure with the foam, you'll want to remove the shroud before draining in the future.
