Toyota Matrix 2012 Oil Filter Cap becomes extremely tight and hard to open I was working on my Friend’s Toyota Matrix 2012 Oil Change and I encountered a situation with its Special Oil Filter Cap. The cap was excessively tight and it was so difficult to open it. I manage to open the cap, but my finger got injured.
I used a wrench and the tool shown in below pictures. It is quite efficent.

I do member I did not over tightened the cap during the last oil change per instruction on the oil filter. Is there any special technique that I was missing? Why the cap became so tight?
