mespe,

You should filter your WVO thru filter bags avaialble from Greasel.com.

I have been doing that and haven't plugged an in-car filter yet.

I put a spigot in a 5 gallon bucket about 2 inches from the bottom. I pour the WVO into this bucket and let it sit a few days so the crap settles to the bottom. Then I open the spigot and let the clean WVO run into and thru the filter bag. This settling makes the filter bags last much longer. You should see the crap that settles out. I then burn off the settled crap in a wood stove to heat my garage.
