I just found UOAs of one of the viscosity grades (0W-30) reformulated to meet GM Dexos1-Gen2. I don’t like that they greatly decreased calcium detergents and somewhat compensated by an increase in magnesium. If you have a GDI engine, that’s good for decreasing LSPI, but I don’t have a GDI engine. Since 10W-30 does not say it is for d1g2 applications, I’m hoping it still has the high calcium and low magnesium formulation.
