So I usually do oil changes on multiple cars for friends etc, it's quicker to bang them out all at once.
We grabbed all the tools and oil etc, and drove to a neighbour's level driveway to work on. Then we jacked up my flatmates car, and drained the oil into the oil pan. Now we need to remove the filter with a specific tool. You can see it just below the blue funnel, with the red and black handle.
My flatmate is telling me he is sure he saw it and brought it with us. I wasn't entirely trusting him because I know he is likely to make the same mistakes as me. Surely we just misplaced it.
Searched everywhere, can't find it. Went home, it's not there either. What the fuck?
Turns out... it was at the bottom of the full oil pan.
Now was is it in the pan before you put the oil or did you drop it in the pan full of oil?
Nope, it was just sitting in the pan and neither of us noticed.
