Oil catch tank question

[window_lee]

for those of you who have a oil catch tank, do you need to put something into the tank in order to filter the oil out???

I have a cheap oil catch tank from ebay and there is nothing in the tank

in the site, people actually put some steel wool in the tank. is it a good idea???

Put stainless steel scrubber pad in the bottom, it will not deteriorate and get sucked into your system. I found them at a dollar store here in Michigan.
