Looks like one of those oils specially designed to meet certain OEM specs, mostly VW 506.01. So don't use it unless you need that spec. I think it's not ideal in engines that do best on 40 weight oils. For instance, my VW 1.8T would burn that stuff up during sustained high speed driving. It even burned GC at 12cst viscosity in such conditions but never noticably burned any 14 cst or higher viscosity oils. But if you have such an engine and do little more than drive around town for 5 minutes each trip, something thinner like this oil would be fine and probably even ideal.
