what sort of filter do i need to run my waste motor oil through before it will be clean enough to run a %5 mix?

Most everyone seems to agree at a minimum you shoudl run it through a paint strainer type filter to get the clumps and crud out it.
there was a thread in here titled "black diesel" that discussed it in detail.

Both those threads have a lot of discussion on filtering WMO before running it.
