I see Duckhams is back!

Green oil, my eldest brother used to swear by it.

I believe Duckhams was taken over by Castrol. A few years ago some of us were horrified to find that although the tin was Duckhams the oil was golden, not green. A couple of years after that the Duckhams brand was dropped.
I suppose it’s been resurected to try to cash in on the classic oils bandwagon.
