I am a little confused about the oil capacity for my newly acquired 67 911S. I read in some of the technical manuals that the tank and engine hold 9 Litres. Yet in an upfixing article on oil levels, it says no more than 7 quarts. I just changed my oil, and put in 9 litres. Did I over do it, and could this cause damage? My dip stick shows the level just below the high mark.
