The sibs and I are cleaning up the family homestead to get it ready for sale Mum and Dad had the place for over 60 yrs. Anyway , my sister found Dad's oil stash. 3 cans of Amalie 50 w and some bottles of 10W40. The 10w40 is destined for my wife's car. I took the Amalie just for curiosity. I'm just curious , when did SB oil appear? When was it superseded by SC? TIA
