I been doing some oil filter investigations and I finally got around to hacking some filters used in my car for the Fram/ST 7317, Purolator PL14610, Wix 51356 size.
The first is a Supertech 7317. I bought it when I first came to this forum based on the hype it was getting and that it was a bargain at $1.77. Too bad it's not a bargain at all with it's filter area of 62 sq in. That's just pathetic. I also was able to use a can opener to split the can open. Everything else about it was fine.
Next is an OEM Nissan 15208 65F01 that may have been dealer installed in my car. It was tiny, but it contained enough filter area at 102 sq in. Twice the ST! To my suprize, it looked like it was made by Fram. It has cardboard end caps and a leaf spring for the bypass value. This became my basis for the minimum quality that Infiniti/Nissan would require for the recommended oil change interval of 3750-7500 miles. Interestingly enough, this filter was replaced with a different model number.
Finally is the Purolator Premium Plus. I was impressed. The bypass value actually had an expensive and robust looking spring setup and the filter area was 115 sq in. Contrary to previous reports, mine came with no string around the filter element. It's quite a bargain when it goes on sale and can be had for a little over $2.
From other reports around the web, the Proline (a budget Purolator equivalent) should have slightly less filter area and a Purolator PUREOne should have more. I think I know what filter to try next after I change my oil in a week or two. By then I'll have a Fram Tough Guard 7317 opened up along with another 4 filters in the Fram/ST 3593a size. More to come. . .
P.S.

I have added my results preceded by an asterisk to that table for the same size oil filter for comparison.
