I've done it, both as brewed biodiesel (BD) and as filtered waste vegetable oil (WVO).

Lots of work. Sure, you can save as much as ~$1.50 per gallon (more for WVO) but it's messy, smelly, and uses some nasty caustic chemicals (BD). You could never make enough for a 44-gallon tow beast - hell, you'd spend most of your time just gathering the WVO - but it would be "OK" to run in a Jetta that goes for two weeks between fills.

Best solution would be to form a co-op and actually run it as a club for paying members. Design the structure such that you've got someone brewing full-time and club members both supply the WVO and pay a nominal fee for usage.

Try it sometime, you might like it. But, trust me, you'll get tired of it once the novelty wears off... - GA
