Very nice write up, very tidy job!
I'm much more messy and always manage to spill old oil all over the place
I dont know if this is a useful thing to do, I always wet the filter with new oil before installing it, I read somewhere that you can get a low oil pressure light if the filter isnt wetted properly when re-starting after fill up with new oil. Could be wrong. Anyway, I always do this and never had a oil warning light on start up after oil change.
I also usually overfill a little bit, but the confusing thing is when re-measuring oil when its warm, the level seems to be lower than when cold?
