I am currently working on a 2016 Chevy LV3 4.3L, the manual and the oil cap says 5W-30, however, the 2014 version of this same engine(First year made) says 0w-20, then I come to find out, there problems with this engine oil pump and timing chain tensioner breaking, Manual even states when extremely cold use 0w-30 for better starting. No mention of 0W-20.
Point being is 0w-20 did not provide "acceptable" wear levels, so it was changed to 5w-30 for later models.
No question here merely another data point why higher HTHS is better.
