Oil Filter Tests by river_rat on BITOG Forums

Now that things have settled several days, here are some new pics of the very last runs:
Left to right in both these is PureONE, Bosch, Purolator Classic, and Toyota OEM Denso.
Top picture is the first run with clean but oiled elements.

Bottom picture is the second run with the
elements becoming pretty dirty with the dirty talc + flour and oil mixture. Looks like the Denso hit its
limit where dirt may be starting pushing through past its peak in-use efficiency.

The third run looked about like the second run pictured here.

1st run: P1, Bosch, Puro classic, Denso

2nd run: P1, Bosch, Puro classic, Denso...almost nothing for "dirt" in the first two
