Any experience with vegetable oil burning engines?

Rylee05 asked:


I have been researching vegetable oil burning vehicles
and am considering buying or converting one. Before I make a big
investment I would really like to talk to someone who has a vegetable
oil car in the Twin Cities area. I would like to ask them about how
well they run here in MN and about their set up. And do they really
smell like French fries? Any websites, recommended books, personal
experience, any information will be greatly appreciated.
