This sort of practice is why nobody will EVER fill my crankcase from a bulk oil tank. As appalling as it sounds, the whole industry can't be trusted. Sorry if that sounds harsh, but you just set it out in detail yourself.
Hate to say, Many dealers do this. And most all of those owners manuals (very few exceptions) Allow '30wt' type oils to be used. My Vehicles' oil cap shows "use 5w-20". however, the "recommended" oils (in the owners manual) include 5w-20, 5w-30, 10w-30, Etc.
