The previous owner used it.
I was changing valve seals on the engine and noticed after 75000 miles how clean it was in the valve cover area.
Never used the oil before but I will keep using it in my 560sl
It worked and kept engine very clean
Oil pressure also on engine is super
I do like syn better but for these old cars which got them this far
I am not messing with something that works
