Yes, dear ol' Duckhams is still going. Alongside Castrol Classic
20/50, it's
the other Number 1 choice for the 'ancients.' Still retains the
original
properties plus a few other modern ingredients to make it better than
ever :)

Straight 50 weight is too thick when it's cold, IMO, particularly with a

20 weight when it is cold) might be OK.
