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. enter image description here

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?

I run into this a lot its a combination of the o-ring and the filter cap bing plastic/rounding off. If you have someone lightly pry against the cap and tap it with a hammer and chisel it usually breaks free.

You should always replace the o ring and apply some clean oil to it when changing the filter
