Grade of fuel for 2.0 cab 1997?

[cheersm8]

Hello, just bought myself a nice old 1997 2 litre cabriolet for the summer, no handbooks or info. I've worked all the controls etc out myself, but can't find any fuel info. need to know if it needs unleaded or super unleaded. Someone tell me please? I've tried "googling" for the answer. I'm in the UK. Also, I'm ebaying for an owners handbook, I can find one there but not for cabriolet. Will the control instructions for the 2 litre coupes be the same as for my cab?
Thanks
