Bio Diesel conversion primer

I have been running Bio Diesel in my truck for over a year now. Bio Diesel is basically slightly refined vegetable oil that can run in ANY diesel vehicle with little to no modifications. The vegetable oil used can be virgin, but it is generally recycled from fryers at restaurants. Yes, the exhaust smells like whatever was fried in it. The best part of running Bio Diesel is that no wars need to be fought over it: it's entirely domestic, supports US farming, it's totally renewable, and it cuts almost all aspects of a diesel vehicle's emissions by more than 50-75%. (The exception is NOx which is about the same). You get slightly less mileage and power (5% decrease) from petro-diesel, but your exhaust smells a lot better and its actually easier on your engine.
