Splashing out, Amber got aromatic oil (8)
I believe the answer is:
bergamot
'aromatic oil' is the definition.
(as in bergamot oil)
'splashing out amber got' is the wordplay.
'splashing out' is an anagram indicator (I've seen this in other clues).
'amber'+'got'='ambergot'
'ambergot' with letters rearranged gives 'BERGAMOT'.
(Other definitions for bergamot that I've seen before include "Kind of orange - great mob (anag)" , "perfume" , "essential oil" , "Oil from a citrus fruit used to flavour Earl Grey tea -- to grab me (anag)" , "Variety of pear" .)
