I'm thinking about starting to make some bio-diesel. A couple questions for the pro's:

Power - I'd like to run it in some of our ag equipment - should I expect any loss of power over "conventional" diesel?

Home heating oil - right now my pickup is still a gas job, so one application I'd want to use the fuel for near-term is to heat my home. I'm assuming that I can use bio-diesel (made from WVO) in my oil furnace? Any changes required to the furnace (nozzle size, air mix, filters, etc.)

Taxes - If this works out, my next truck may very well be a diesel - do folks typically pay up for the road taxes for home-brew bio-diesel?

TIA for the help...
