base your oil choices on wear numbers by having UOA's done and not on oil pressure, color, and/or how pretty the bottle is or isn't...lol Every car will be different and what oil works great for one car may not be the best choice for another. I will say that, based on UOA's, the LS1's seem to like the European spec stuff.....GC 0w30, Mobil 1 0w40, etc.

What do you guys think about a grade like 5W-50? I know my last oil change was done with that grade in the Mobile 1 Synthetic. Will it damage any parts? Frankly I don't think so but I want advice or people who know soemthing about that oil in LS1.

run it for 3-4,000 miles and get a UOA done, that's the ONLY way you will know how -your- engine likes it.
