ok,,u can type the oils u want to research in the search section at the top of this site. U will find a million opinions on oils of all flavors,lol. I have use Napa synthetic oil in my quest to settle on my current oil. Napa synthetic oil did well in my van, by well I mean, the engine did not blow up or use oil, so that's my experience. I have used many brands of oil on that van years ago, mostly dino and what can I say,,,the van is still running. Napa synthetic will do well.
