Yeah - I learned the hard way about checking for having (on hand) both the oil and filter beforehand for any car I do a change on.
LONG time ago I learned that the hard way (well - not THAT hard as I had a car to use to get what I needed - but, the lesson stuck).
Regardless of being able to go down to get what you need - still a PITA compared to just being able to finish out the job in the first place.
