Ok, so I have seen a wide range of different oil viscosity rating choices by the many members here who are doing their best to avoid any cam/lifter future failures on the 5.7L.
From what I have seen it appears that most of us (to include myself) uses 5W-30 when using Redline oil. Now, I would like to know who is using 5W-40 or even 0W-30 or 0W-40. For 0W-40, is the flow going to be good enough at normal op temp? I personally feel 0W-30 would seem to be the best choice however I want to know why some use 0W-40 and if there is proof its really effective in the 5.7L. Why is 5W-30 the better choice over 0W-30?
