<DIV>Someone was wondering when detergent oils were initiated. I grew up
right down the street from the Kendall Refinery, and the addition of detergents
was a big deal. The detergents addition to old curded engines was a
problem as the curd could-would break loose and plug up the oil pump
screen. Any way, as I remember the switch over was 1951/1952 period.
It is hard to find non-detergent these days in the better grades of oil.
