I am new here but will this be any good for me

Hi I am new here and have just taken delivery of my 2000 TD5 today and I am thrilled to bits except the £106 fill up anyway I normally hang around on the volkswagen forum as this is me hobby messing about with old dubs. oh I will cut to the chase a guy on there is selling these things (check the link) now being new to this landrover thing I am curious as to whether me disco will run on this stuff and is it worth getting one, I do have access to used oil from the local kebab shop.
what I really ant to know is will the disco run on this stuff without harming it.

Lots of fuel filters..... and i'd personally wanna see some decent results before parting with that much money.
