Where did I say that there was no spillage. I said "I never end up with oil everywhere" as there are ways to minimise spillage.
I don't want oil on my head, face, hair etc. I don't want it running up my arm and soaking my clothes and I don't want it lying on the exhaust or subframe of someone's car or, on the floor where I am working. Therefore, before undoing anything that is likely to make a mess, I do what whatever I can to prevent it.
It's not rocket science, one look at the filter will tell you what is going to happen when you loosen it so be prepared.
I'm not here to justify my existence by replying to have you ever done this that and the other? So, I'm not going to go down that road.
