What Oil And Filter Are You Using And Why?

[john]

What oil and filter are you using and why?

I was told to only use a mitsu filter by several people. Why is this??? The napa filter I have on my car is larger than the stocker. Why would we want a smaller filter? How is a mitsu oil filter better on lifter tick? I dont see how this works as it only filters the oil. Does it let more through?

Thanks in advance, John.
