what oil is used in convertible hood reservoir
I have used Fuchs Titan CHF 11S which used to be called Pentosin CHF 11S. It is green. If what is left in your reservoir is yellow, drain it all out and replace it because the yellow stuff becomes gelatinous and is PITA to get rid of once this has happened.
Univis was the original yellow fluid.
As Eric stated, Jaguar switched to Pentosin CHF 11S.

P.S. I still have a half tin of UNIVIS on my shelf from 25 years ago.
