A question on this: pic 6 shows the small trap door in the under tray that needs to be removed to access the drain plug. I read another fellow's comments here and he said that the oil did not actually drain straight out, but at an angle which caused it to soak the top of the undertray causing a terrible mess. Yet another fellow said he used the removed trapdoor to divert the flow into the drainpain.
I was thinking about this when I saw pic 6, but your comment is also rather confusing on the subject:

Oil comes out straight down in the N52 which I gather is not the case in the N54

What exactly do you mean by that? Does it flow straight down or not? If not, which way does it flow? Is there any merit to the fellow's suggestion to use the trapdoor to divert the oil?
Also, I seem to recollect seeing stickers under the hood saying BMW recommends Castrol, but not which specific oil. Which oil did you use?
Thanks for any info,
