I did a fill with that stuff in my new 1976 Plymouth Volare with the straight 6 225, I had about a years driving back and forth from going to school in Harrisburg (a three hour drive) before I tried that oil.
I also remember using on that same vehicle a special oil filter that was advertised as having a special wax plug on the bottom of the filter that was shown in the commercial as a yellow disk about 3/4 of an inch thick taking up the entire bottom of the oil filter. The commercial said that the wax disc melts during the life of the oil change, and keeps the quality of the oil better during the life of the oil use.
