Not a guru by any means, but at that age, I'd be surprised if it won't run on bio.
Also, at that age, you are liable to get a few problems with the bio shifting muck out the tank, pipes disintegrating, and the fuel filter housing having a fetch.
All might sound a bit terrifying, but don't worry about it, it's all pretty simple.
I would be worth investigating if it will run on WVO. It will need to be a indirect injection, unless it's a DI which is similar to the Transit, which is fine on WVO.
