ford super plus did used to look pinkish when in the header tank but in a cup neat its more orange and has a strange effect when looking at the water surface, we quaratined about 2000 litres of the stuff when a technician noticed the change as he claimed it was "more brown" boring story but something i remember checking as for 3 days we had no antifreeze and the next batch that came in was the same

ps: what about "purple" antifreeze or we not going to start that conversation lol
