Currently it takes a gallon and a half of real deisel fuel to make a gallon of bio deisel fuel. Yea, that makes sense... not!.

Soren, where did you get that number? From what I have read, you have to heat the vegetable oil to 130dF before you add the catalyst. Other than that you need some electicity for mixing and washing. FYI, it takes a lot higher temps than that to crack all the components out of crude oil. This site claims you can make a gallon of bio-diesel for about $0.50 a gallon. With regular diesel costing $2.75 in my area, I'd say that is quite a savings. Hey, we make our own beer (with no political implications), so why not diesel? I've been interested in this topic for a while. I'd like to discuss it more, but this thread has been hijacked enough already.
Back on topic, I always burn premium in my Speedy. I'm afraid that regular isn't good enough, and I've gotten burned a few times on watery mid-grade (probably from one particular gas station near my house). It made my bike run like kraap on several occasions. To keep things simple and avoid problems, I just grab the premium nozzle. It costs me and extra buck or two on fillup. No big deal. That's the cost of peace-of-mind.
