Multi fuel car

I have a truck that can burn many different things including used transmission fluid, diesel, engine oil, cooking oil and so on.

What is the best way to filter used cooking oil before pouring it into my fuel tank? This is not really a Hummer but a Deuce and a Half.

The biofuel “greaser” crowd is an entire subculture. Let me suggest that you’ll get more and better information from a greaser website.
