My thought is that there were very few choices for synthetic oil at that time. Now there are many choices.
Here'* a thought. Doing a oil change with filter is 4.5 quarts. The jugs are 5 quarts. You do a oil change and have half a quart left over. While the car is up and the pan is draining you can remove the SC plug, suck out the oil, then add 8 oz and put the plug back. About 5 mins. Now your oil has finished draining from the oil pan and you can finish the oil change. Changing your snout oil with each oil change is totally easy.
