While watching an episode of street outlaws last night I noticed they were dumping O'Reilly full synthetic into one of their engines. I found it interesting with all the money they put in to their cars, that they chose to use a house brand oil. I understand they use very short drain intervals, but it was still surprising. Do we maybe overthink this oil thing a little bit? It seems any oil will do the job if it meets the spec. Also what does the additive package for the O'Reilly full synthetic look like? Is it similar to Napa or Carquest, lacking moly, containing sodium
