Also, both the first oil change and this one, I ended up with an extra new o-ring. The oil filter kit comes with: 1-small, 2-medium, 1-large, and 1-extra large. However, when I removed the old o-rings from the oil filter shaft, there were only: 1-small, 1-medium, 1-large, and 1-extra large. Has anyone else had this problem? Thanks again for your help in advance.
