Check the bottom sills beneath your doors, common place for it to pool also, pop the bung, drain and replace.
From a dirty old port car washer, vents are your enemy, they gather and hold leaves seeds and mud, perfect for rust and plant growth. Then chassis rail ,and anywhere that has wheel arch covers, plastic surrounds any where that creates a pocket , for crap to settle.

The last time I did an oil change on my van I was very glad the mechanic had written on top of the air filter " 8.3L with filter". Firstly I wouldn't have had enough oil to do the change, and secondly I would have used a 4L container to try and catch just over 8L
Seems like a shitload of oil but it is a 3L engine I guess
