In my own case, the Pure One seems to keep my oil cleaner for a much longer time. This has been true in Both my 88 S/4 NA's and my Crown Victoria. I'm sure some will say, Nah, no way. I documented these results myself.

 

On my 10th AE i have an Atkins Rotary filter, and on the Vert im running a napa 1356

 

I use the Honda S2000 filter on my 7. I just switched from the smaller Honda filter to the bigger one.....We shall see how this one does....
