To add some detail Mal..............
Ford Super Plus Premium Antifreeze. This is what my Roadster came with, and is a translucent blue/violet colour.
Contains Ethanediol
ethanediol (ˈiːθeɪnˌdaɪɒl; ˈɛθ-)
n
(Elements & Compounds) a clear colourless syrupy soluble liquid substance, used as an antifreeze and solvent. Formula: CH2OHCH2OH. Also called: glycol or ethylene glycol
I wrote a guide to antifreeze a while ago in Miscellany, it might even be on TM. I'll see if I can find it. Basically colour means nothing, there are versions of traditional and OAT coolants in most colours, so always read the spec sheet.
