So...
No 502 requirement for your engine? I'm not a VW expert but how is it that you knew O'Reilly oil was being used and you knew it wasn't right, but it stayed in the engine?
Had similar problem when dealer "used Dino oil w/o checking proper spec"? It happened again with this oil? You seem to have a lot of oil related problems that you are aware of, yet continue to work around. Did the engine shut down the second time or just an "alarm"?
And it wasn't a similar problem with the dealer if that issue was oil foaming. If the dealer used the wrong oil that's a huge problem.
And you think that we should use caution when using that oil why?

Oil level good, no foaming. Kept rpm below 3k, okay. 100 miles later, outside temp now 83 degrees, alarms again, can not travel freeway speeds. Limped in to oil change center. New change later no problems. Valvoline 5w-40, Mighty filter. Did oil viscosity drop or filter relief problem? Hard to say. Had similar problem when dealer used Dino oil w/o checking proper spec. Caused oil foaming and low oil pressure.
